Grounding sheet loaded into a washer

How to Wash Grounding Sheets Without Losing Conductivity

Yes, you can wash a grounding sheet (also called an earthing sheet) in a washing machine, but gently. Use a cool wash, a plain liquid detergent, no fabric softener and no bleach. Then dry it away from high heat. The conductive threads woven into the cotton are what make the sheet work, so the aim of every wash is the same: clean the fabric and leave the threads undamaged.

This guide covers the full routine, from the first wash to the weekly one. It also covers the mistakes that cause most conductivity problems, and how to check that a sheet still works afterwards.

TL;DR

  • Grounding sheets are washable. Use the machine on a gentle cycle at a low temperature, around 30 to 40°C (86 to 104°F), and read your product’s care label first.
  • Use a plain liquid detergent without bleach or built-in softener. Leave out fabric softener, dryer sheets and anything else that leaves a coating.
  • Avoid hot washes and the dryer. Research on silver-coated fabrics links 60°C (140°F) washes and machine drying to more damage. Line dry or dry flat instead.
  • Wash regularly, because sweat, body oils and lotions build up on the threads. Every one to two weeks is a sensible range for most people, adjusted to how much you sweat.
  • After washing, test the sheet and your wall socket (outlet). A grounded sheet should still give a low-resistance reading with a multimeter.

Why washing a grounding sheet is different from washing normal bedding

A grounding sheet looks like ordinary cotton bedding. The difference is a network of conductive threads, commonly silver-based, running through the weave. These carry the earth potential from your wall socket’s earth pin (the ground pin, in North America), through the cable, to your skin. If that network is damaged or coated, the sheet still feels like a sheet but no longer does its job.

That is why laundry habits matter more here than with standard bedding. Research on washing silver-coated conductive fabrics shows that temperature, detergent chemistry, mechanical friction and machine drying all affect the conductive layer. In that 2024 peer-reviewed study, washing at 60°C (140°F) and machine drying caused more degradation, while temperatures below 40°C (104°F) caused relatively less damage. A wider review of e-textile washability makes the same point from another angle: the effect of a wash depends on time, temperature, mechanical action and chemistry, and the right conditions vary from one textile to another.

Two practical conclusions follow:

  1. Treat the wash as something you control. Temperature, product choice and drying are all in your hands.
  2. Your product’s own care label wins. Different grounding sheets use different yarns and constructions. If the instructions that came with yours differ from anything below, follow them.

Can you put a grounding sheet in the washing machine?

Generally yes. Most grounding bed sheets are made for regular machine washing, which is why they are practical for daily use. Hand washing is not required, and dry cleaning is not a good idea, because solvents and heat can affect the threads.

The exceptions are different products. A grounding mat made from vegan leather or similar material is a wipe-clean surface, not a laundry item. If you sleep on one, you clean it with a damp cloth. Our grounding sleep mat is in that category, so treat it very differently from a cotton sheet. Never put a mat in the washing machine.

The cable and plug are never washed either. Unplug the sheet and detach the cable before every wash, then keep the cable aside.

Before you wash: a short checklist

A minute of preparation prevents most laundry problems.

  1. Unplug and disconnect. Remove the cable from the sheet’s connector and from the wall socket. Keep the cable dry.
  2. Read the care label. Note the maximum temperature and any restrictions.
  3. Check the drum. Make sure no zippers, hooks or Velcro from other items can snag the sheet.
  4. Wash it with similar items or on its own. A grounding sheet is happiest washed alone or with soft cotton bedding. Avoid washing it with heavy items such as towels, jeans or anything with zippers. Friction is one of the factors that wears down conductive coatings.
  5. Do not overload the drum. Sheets need room to move and rinse properly, so fill the drum no more than about three-quarters.

How to wash a grounding sheet in a washing machine: step by step

1. Choose a low temperature

A wash at 30°C or 40°C (86°F or 104°F) is a sensible default for cotton bedding with conductive threads, unless your label says otherwise. It removes sweat and skin oils well enough in a modern machine, and it avoids the heat that the 2024 study associated with greater degradation. Avoid 60°C (140°F) and above, even though many people use hot washes on bed linen for hygiene reasons. If you want a sanitising wash for illness, check your product’s instructions first and do not make hot washes a habit.

If your machine has Cold, Warm and Hot settings instead of numbers, as most US machines do, choose Cold or Warm. If your machine only washes in cold water, that is fine. A cooler wash is gentler on the threads.

2. Pick a gentle cycle

Use a delicate or gentle cycle, or a cotton or normal cycle with reduced spin if that is what your machine offers. Less mechanical action means less abrasion on the threads. A high spin speed is not necessary for a sheet. If your machine shows spin speeds, 800 to 1,000 rpm is plenty. If it shows Low, Medium and High, choose Low or Medium.

3. Use a plain detergent without bleach or softener

A liquid detergent is usually easier to rinse out than powder, which can leave residue if it does not fully dissolve in a cool wash. Brands and labels differ from country to country, so check the ingredients rather than the brand name. Look for:

  • No bleach or optical brighteners. That includes “oxi”, “whitening” and “colour-brightening” formulas. In the 2024 study, the detergent that contained bleach and brighteners changed the fabric’s colour the most.
  • No built-in softener, so skip “2-in-1” and “with softener” products.
  • A fragrance-free formula without essential oils or dyes, because perfumes and oils can leave a film.

Your everyday detergent is usually fine if it passes those checks. You do not need a wool or delicates wash. In the same study, a pH-neutral wool detergent did more damage to the silver layer than a standard powder did.

Use the amount recommended for a lightly soiled load. Extra detergent does not mean a cleaner sheet. It means more residue on the fabric.

4. Leave out fabric softener

This is the most common mistake. Fabric softeners (also called fabric conditioners) work by depositing a thin layer of softening agents on fibres. On a grounding sheet, that layer can sit on the conductive threads and interfere with contact. Leave the softener compartment empty. If the sheet feels stiff, a second rinse is a safer fix than softener. Dryer sheets coat fabric the same way, so leave those out too.

5. Skip bleach, whiteners and stain boosters

Chlorine bleach, oxygen bleach and many “laundry booster” products are chemically aggressive. In the 2024 study, the detergent that contained bleach caused the most colour change in the silver fabric. For a stain, dab with a little of your detergent diluted in water before the wash, rather than reaching for a stain remover with bleaching agents. Check the label of anything you use.

6. Add an extra rinse if needed

If you live in a hard-water area, or if you notice detergent residue on dark sheets, add a rinse. Residue is exactly the kind of film you want to avoid on the threads.

How to dry a grounding sheet

The 2024 study that tested silver-coated fabrics found that machine drying, like hot washing, produced more degradation of the conductive layer. So the safest default is simple:

  • Line dry or use a drying rack. Outdoors, a dry, breezy day works well. Indoors, spread the sheet over a rack in a ventilated room. In humid weather, a fan or dehumidifier speeds things up.
  • Keep it out of strong direct heat. Do not drape it over a heater or radiator.
  • If you must use a dryer, choose the lowest heat or an air-only setting, keep it short, and finish drying on a line or rack. Check your care label before doing this. On a washer-dryer, choose a wash-only cycle so the sheet does not go straight into heat drying.
  • Make sure it is fully dry before it goes back on the bed. A damp sheet is not a good idea for grounding, as moisture can affect readings and is a poor start to a night’s sleep.
  • Do not iron on a high setting. If you press it at all, use a low heat, and ideally skip it.

Air drying takes longer in winter and in wet or humid seasons, so it helps to own a spare set. Alternating two sheets means you can wash one while the other is in use, and neither gets rushed into a dryer.

Hot water or cold water for sheets?

For ordinary bedding, many households wash at 40 to 60°C (104 to 140°F). For a grounding sheet, the sensible choice is cooler. Cold to warm water (30 to 40°C, or 86 to 104°F) gives you a clean sheet and less thermal stress on the conductive yarns. The research points the same way: lower temperatures caused relatively less damage than 60°C (140°F) in the silver-coated fabrics tested.

That study tested fabrics in a laboratory, not every grounding sheet on the market, so it shows a direction rather than a guaranteed limit for your product. Your care label is the final word on the maximum temperature.

What to avoid: quick reference

Do Don’t
Wash at 30 to 40°C (86 to 104°F) on a gentle cycle Wash at 60°C (140°F) or above
Use liquid detergent without bleach or softener Use bleach, whiteners or stain boosters
Run an extra rinse if needed Add fabric softener, dryer sheets or scent beads
Line dry or dry flat Machine dry on a hot cycle
Unplug the cable before washing Wash the cable or plug
Wash with soft cotton items Wash with zippers, towels or abrasive items
Wipe leather or vegan leather mats with a damp cloth Put a grounding mat in the machine

How often should you wash a grounding sheet?

There is no single rule that every manufacturer agrees on, and you should follow the guidance for your own sheet. As a practical approach, treat it like any bed linen you sleep on directly, and wash it every one to two weeks. Wash sooner if:

  • You sweat heavily, especially in hot weather or a room without air-conditioning.
  • You have been ill with a fever.
  • You apply body lotion, oils or creams before bed. These can leave a film on the fabric, so it helps either to let them absorb fully first or to wash the sheet more often.
  • You share the bed with a pet.

Be aware that washing more often adds wear. The balance is a clean sheet with the fewest harsh cycles, which is why a gentle wash at a low temperature matters more than a strict calendar.

Your first wash: should you wash a new grounding sheet?

Many people wash new bedding before use, and that is a reasonable habit for a grounding sheet too, provided you use the same gentle method: low temperature, a plain detergent and no softener. Read the instructions that arrive with the product, as manufacturers may give specific guidance for the first wash. Do not use a hot wash or a heavy-duty powder just because the sheet is new.

A first wash is also a good moment to take a baseline reading, which brings us to testing.

How to check your sheet still works after washing

Washing should not change how a grounding sheet performs, but it is worth checking, especially after your first few washes. There are two parts: the socket and the sheet.

Check the socket first

A grounding sheet only works if the earth (ground) connection in your socket is sound. A plug-in socket tester shows whether it is wired correctly, so use one made for your country’s sockets. Our socket tester fits the Type G sockets used in Singapore, Malaysia, Brunei and the UK. In the US, Canada and Australia, hardware stores sell testers for local outlets.

In the US and Canada, a two-prong outlet has no ground connection, so a grounding sheet cannot work from it. Some older homes also have three-prong outlets with no ground wire behind them. A tester will show this. If you are unsure about any result, ask a qualified electrician to look at it. Do not try to fix wiring yourself.

Check the sheet

With a multimeter set to measure resistance, you can check that the conductive threads still carry a connection from the connector point across the sheet. A sheet in good condition shows low resistance across its surface. Because acceptable readings differ by product, use the range given in your product’s guide. If you have a Naturalive sheet, our setup guides explain how to connect and confirm it: the fitted sheet setup guide, the flat sheet setup guide and the general five-minute setup guide.

If the reading is poor

A poor reading after a wash usually comes from one of five causes:

  1. Residue. Detergent, softener or body products on the threads. Run a second wash with no detergent at a gentle temperature, with an extra rinse.
  2. A damp sheet. Dry fully and test again.
  3. A connection issue. Check that the cable and connector are clean, dry and pressed in firmly.
  4. A faulty socket. Try another socket checked with a tester.
  5. An adapter without an earth. If your plug goes through an adapter, check that the adapter connects the earth pin. Many travel adapters do not.

If none of these helps, contact the retailer you bought from, with your order details and the readings you recorded.

Perspective: why we think washing is part of the product

We make grounding sheets, mats and accessories that connect to the earth pin of an ordinary wall socket without using any electricity. Customers who buy them are usually after better sleep, a calmer evening or quicker recovery after training. The research on those outcomes is something we publish openly, with the studies and their funding sources, because we think you should be able to judge it for yourself.

Here is our view on care. A grounding sheet is a piece of equipment that happens to live in your bed. You would not put a cable through a hot wash with bleach and expect it to work, and the threads in a sheet deserve similar respect. The good news is that the care is not demanding. Cool water, a plain detergent, no softener and air drying do nearly everything, and a quick check with a tester pen gives you confidence.

We also think the best protection is routine. People who have a second set, wash on a regular schedule and keep body products off the sheet seldom have problems at all. That is why every order includes safety accessories such as a tester pen: understanding and checking your setup is part of getting reliable results over months and years, not only on day one.

Common myths about washing grounding sheets

“Hot washes are more hygienic, so I should use them.” Hot washing kills more germs, but it is also the condition most associated with degraded conductive coatings in the research above. A regular, gentle wash does the job for normal use.

“Fabric softener makes it softer, which is better for sleep.” It also coats the threads. Choose a second rinse instead.

“More detergent means a cleaner sheet.” Excess detergent stays in the weave. Use the dose for a lightly soiled load.

“If it still feels the same, it still works.” Feel tells you nothing about conductivity. Only a measurement does.

“I can wash my mat too.” No. Mats are wiped clean.

Looking after the rest of your grounding setup

A few related habits make washing easier and extend the life of everything:

  • Pillowcases. A grounding pillowcase sits against your face and hair, so it collects oils quickly. Wash it with the sheet using the same method.
  • Fitted and flat sheets. Treat both identically. If you use both, wash them together and avoid overfilling the drum.
  • Cables. Wipe with a dry cloth. Replace any cable that is frayed or damaged.
  • Mattress mats. Spot-clean with a damp cloth and let it air dry fully.
  • Skin products. Let creams absorb before you get into bed.

If you want to understand what the sheet is doing once it is clean and connected, our articles on whether grounding sheets work and on grounding sheets and sleep quality go through the studies in plain language.

Choosing sheets that are easy to live with

If you are still deciding, think about care as part of the choice. A fitted sheet stays put and gets washed like your regular bottom sheet. A flat sheet is used over you, so it can be washed on its own. A spare of either makes washing stress-free.

We offer a fitted grounding bed sheet, a grounding flat sheet and a grounding pillowcase, as well as mats and accessories. You can see the full range in our grounding sheets collection. Every order includes safety accessories such as adapters and a tester pen, so you can check your socket and setup from the first night.

Every sheet comes with a cord and a Type G plug, which fits sockets in Singapore, Malaysia, Brunei and the UK. In countries with other sockets, such as the US and Canada, use a plug adapter that connects the earth pin.

The fitted sheet comes in four widths. All are 203 cm (80 in) long, with a pocket for mattresses up to about 30 cm (12 in) deep. Bed names differ between countries, so measure your mattress width before you order.

  • Single: 93 cm (37 in) wide
  • Super Single: 113 cm (44 in) wide
  • Queen: 153 cm (60 in) wide
  • King: 193 cm (76 in) wide

Grounding Flat Sheet

If you would rather not wash a bedding item at all, our grounding mats wipe clean and can be used alongside, or instead of, a sheet.

A simple washing routine to follow

  1. Unplug the cable and remove it from the sheet.
  2. Wash alone or with soft cotton at 30 to 40°C (86 to 104°F) on a gentle cycle.
  3. Use a small dose of liquid detergent without bleach or built-in softener. No fabric softener.
  4. Add an extra rinse if you have hard water or sensitive skin.
  5. Line dry or use a rack, away from heaters and radiators.
  6. Make the bed with the sheet only when it is fully dry.
  7. Reconnect and test with a tester pen or multimeter, especially after the first few washes.
  8. Repeat every one to two weeks, or sooner after sweating, illness or heavy body-product use.

FAQ

Can you wash grounding sheets?

Yes. Most grounding bed sheets are designed to be machine washed, and regular laundering keeps sweat and oils from building up on the conductive threads. Use a gentle cycle and a low temperature, with no bleach or softener, and check your care label first. Mats made from leather or vegan leather are wiped clean instead.

Are grounding sheets and earthing sheets the same thing?

Yes. In the UK, Australia, Singapore and Malaysia, the electrical safety connection is called “earth”, so many people there say earthing sheets. In the US and Canada, it is called “ground”, so grounding sheets is the usual name. The care advice is the same.

Can you use fabric softener on a grounding sheet?

No. Softeners leave a coating on fibres, and on a grounding sheet that coating can sit over the conductive threads. The same goes for fabric conditioner and dryer sheets. If the sheet feels rough, run an extra rinse and shake it out before drying.

How do you dry a grounding sheet?

Line dry it or lay it over a rack, away from direct heat. Research on silver-coated fabrics links machine drying to more damage of the conductive layer, so a hot dryer is best avoided. Make sure the sheet is completely dry before you use it again.

Should grounding sheets be washed in hot or cold water?

Cool to warm water, around 30 to 40°C (86 to 104°F), is the safer choice. On a machine with Cold, Warm and Hot settings, that means Cold or Warm. A 2024 study found that washing at 60°C (140°F) caused more degradation to silver-coated fabric than lower temperatures did. Always follow your product’s own maximum temperature.

How do I know my grounding sheet still works after washing?

Check the earth connection in your socket with a plug-in socket tester, then measure the sheet with a multimeter and compare the result with the range in your product guide. If the reading is poor, dry the sheet fully, check the cable connection and rewash without detergent if you suspect residue.

Can I use a grounding sheet with a two-prong outlet?

No. A two-prong outlet has no ground connection. Use a three-prong outlet and check it with an outlet tester first, because some older homes have three-prong outlets that are not grounded.
