The Importance of Washing a Heated Mattress Pad

Washing a heated mattress pad is an important part of maintaining its performance and extending its life. A clean, well-maintained heated mattress pad will last longer and keep you warmer at night. Here are some reasons why washing your heated mattress pad is essential:

Health –

A dirty or unhygienic mattress pad can be a breeding ground for bacteria, dust mites, and allergens. These contaminants can increase your risk of developing respiratory problems such as asthma or allergic reactions. Regularly washing your mattress pad decreases the presence of these allergens and prevents them from coming into contact with your skin while you sleep.

Comfort –

A dirty or stained mattress pad can be uncomfortable to sleep on. Washing your heated mattress pad eliminates dirt buildup, oil residues, and any other unwanted material that could make your bedding unpleasant to use. This ensures that you stay comfortable during the night and wake up feeling refreshed in the morning.

Performance –

Dirt build-up can impede the performance of your heated mattress pad by reducing its heat retention and making it less effective. Washing your mattress pad regularly can help to reduce this build-up of dirt, restore its performance, and make sure that you stay warm while you sleep.

Keeping your heated mattress pad clean is an important part of maintaining its performance and extending its life. By washing your mattress pad regularly, you can ensure a healthier sleeping environment, greater comfort, and improved performance for years to come.

10 Methods How to Wash a Heated Mattress Pad

Method 1: Check the Manufacturer’s Instructions

Before starting the cleaning process, it’s essential to read the manufacturer’s instructions provided with your heated mattress pad. These instructions will provide specific guidance on how to clean and care for your particular model.

Though some heated mattress pads are machine washable, others must be spot-cleaned with a damp cloth or require professional cleaning. Make sure to read the directions carefully in order to avoid damaging or voiding the warranty of your heated mattress pad.

Method 2: Unplug the Mattress Pad

Ensure that the heated mattress pad is unplugged from the electrical outlet before attempting to wash it. This will prevent any accidents or damage to the pad and ensure your safety during the cleaning process.

Ensure That the Heated Mattress Pad is Unplugged

Once the mattress pad is unplugged, you can remove it from the bed. If the pad is too big or bulky to handle, you may need help from another person. While handling the mattress pad, take care not to snag or tear it.

Method 3: Spot Clean Small Stains

If you notice any small stains or spills on the mattress pad, you can spot-clean them before washing the entire pad. Use a mild detergent mixed with water and a clean cloth or sponge to gently blot the stain.

Avoid using excessive water, as it may damage the electrical components. Rinse out the detergent with a damp cloth. Allow the area to air dry thoroughly before using the mattress pad again. If the stain persists, you can try using a specialized stain-removal product designed for use on heated mattress pads.

Be sure to test any products in an inconspicuous area before using them on the pad itself. If the stain remains after spot cleaning, you may need to wash the entire mattress pad. With proper care and maintenance, your heated mattress pad should last for many years.

Method 4: Remove the Controls and Wires

Most heated mattress pads come with detachable controls and wires. Disconnect these components from the mattress pad by following the instructions provided by the manufacturer. Separate them carefully to avoid damaging the wires or connectors.

When they are detached, set the control and wires aside so that they can be safely washed later. Once you have removed them, you can proceed with washing the mattress pad. Be sure to reattach the controls and wires after the heated mattress pad is dry. This will ensure that your mattress pad continues to work properly.

Method 5: Hand Wash or Machine Wash, if Applicable

Depending on the manufacturer’s instructions, you may be able to either hand wash or machine wash the heated mattress pad. If hand washing is recommended, fill a basin or bathtub with lukewarm water and a mild detergent.

Lukewarm Water and a Mild Detergent

Submerge the pad and gently agitate it to ensure the detergent reaches all areas. Allow it to soak for about 15 minutes. Drain the basin and rinse the pad thoroughly. Squeeze out excess water, then roll it in a towel to absorb moisture. Follow all instructions regarding drying.

Method 6: Rinse Thoroughly

After soaking, rinse the heated mattress pad thoroughly to remove any detergent residue. Empty the basin or bathtub and refill it with clean water. Submerge the pad and swish it around to rinse off the soap. Repeat this step until the water runs clear, indicating that all detergent has been removed.

When finished, squeeze out the excess water and hang the pad on a clothesline or drying rack to dry. While it is drying, gently stretch the pad back into its original shape. Once completely dry, the heated mattress pad will be clean and ready to use.

Method 7: Machine Washing Steps

If the manufacturer allows machine washing, follow these steps instead of hand washing. Place the heated mattress pad in a front-loading washing machine and select a delicate or gentle cycle. Use a mild detergent and avoid adding any fabric softeners or bleach. Set the water temperature to cold or lukewarm to prevent damage.

After the cycle is complete, hang dry or tumble dry on low heat. Remember to check the manufacturer’s instructions for specific recommendations before washing. Try to be mindful of the washing instructions to ensure proper care and longevity of the heated mattress pad.

Method 8: Drying the Mattress Pad

After washing, gently squeeze out excess water from the heated mattress pad. Avoid wringing or twisting it, as this can damage the internal heating elements. Lay the pad flat on a clean and dry towel and roll it up, pressing gently to remove any remaining water. Hang the pad up on a clothesline or lay it flat on a dry and clean towel.

Allow it to air dry, away from direct sunlight, and check it every now and then to make sure it is drying properly. Once the heated mattress pad is completely dry, fold or roll it up carefully and store it in a cool, dry place ready for use.

Method 9: Air Drying

Once you’ve rolled the pad in the towel, unroll it and transfer it to a well-ventilated area for air drying. Avoid exposing it to direct sunlight or using a dryer, as the heat can damage the electrical components. Allow the mattress pad to dry completely before reconnecting the controls and using it again.

Always make sure to thoroughly inspect the pad for any tears or frayed edges before plugging it in and using it. If any wear is noticeable, contact the manufacturer for necessary repairs or replacements. For added safety, never leave a heated mattress pad unattended while it is plugged in and operating.

Method 10: Reassemble and Test

After the heated mattress pad has dried thoroughly, reassemble the controls and wires according to the manufacturer’s instructions. Ensure that all connections are secure and the wires are properly attached. Plug the pad back into the electrical outlet and test it to ensure that it’s functioning correctly before using it again.

If it doesn’t seem to be heating properly, check the connections and contact a professional for assistance. With proper care and cleaning, your heated mattress pad should last a long time. Enjoy the comfort and relaxation that comes with sleeping on your warm, clean mattress pad.


In conclusion, knowing how to wash a heated mattress pad for optimal care will make sure you get long wear out of this calming bedding item. It is important to read the instructions on the label to determine any additional precautions and warranty information from the manufacturer as it may differ depending on the model of heated mattress pad.

Using the right steps, you can come away with a clean and fresh mattress pad that will last through regular use.  Additionally, be mindful of what kind of detergent and cycle you use when laundering your heated mattress pad.
