How Often Should You Wash a Waterproof Mattress Cover?
September 24, 2026
A waterproof mattress cover should generally be washed whenever it becomes soiled and regularly according to the manufacturer's care instructions. For people managing adult incontinence or frequent bedwetting, the cover may need to be washed after each accident. Between accidents, routine laundering helps keep the sleeping surface fresh while maintaining a cleaner environment.
The exact schedule depends on how the mattress cover is used, how frequently accidents occur, and the manufacturer's recommendations.
When Should You Wash a Waterproof Mattress Cover?
A waterproof mattress cover used for occasional protection may not require washing as frequently as one used for daily incontinence care.
Consider washing the cover:
- Immediately after an incontinence accident
- When it becomes visibly soiled
- When odors develop
- After exposure to significant spills
- As part of a regular bedding-cleaning routine
For caregivers managing frequent nighttime incontinence, keeping an extra clean cover available can make changing the bed much easier.
Should You Wash an Incontinence Mattress Cover After Every Accident?
If urine or another bodily fluid soils the cover, it should generally be cleaned before being used again. Allowing moisture to remain in the fabric can contribute to odors and make stains more difficult to address.
A reusable incontinence mattress protector can be especially useful for ongoing care because it can be removed, laundered, and returned to the bed rather than discarded after each use.
Always follow the specific washing and drying instructions provided with the product.
How Do You Wash a Waterproof Mattress Cover?
Waterproof materials require proper care to preserve their protective qualities. Washing methods can vary between products, so the manufacturer's instructions should take priority over general laundry advice.
Before washing:
- Check the care label for recommended water temperature
- Use only approved detergents and cleaning products
- Avoid bleach or fabric softener unless specifically permitted
- Make sure the cover has enough room to move inside the washer
- Follow the recommended drying method and temperature
Excessive heat or harsh cleaning products can damage some waterproof materials, potentially reducing their effectiveness over time.
Why Proper Drying Matters
A waterproof mattress cover should be completely dry before it is placed back on the bed.
Trapped moisture can create an uncomfortable sleeping surface and may contribute to unwanted odors. If machine drying is permitted, use the manufacturer's recommended temperature rather than automatically selecting high heat.
Having a second mattress cover available allows caregivers to remake the bed immediately while the soiled cover is being washed and dried.
How Can You Make a Waterproof Mattress Cover Last Longer?
Regular cleaning is important, but washing a waterproof cover correctly is just as important as washing it frequently.
To help extend its useful life:
- Follow the manufacturer's laundering instructions
- Address accidents promptly
- Avoid unnecessarily harsh chemicals
- Inspect the waterproof barrier for wear
- Check seams and fastening points periodically
- Replace the cover if liquid begins passing through
A damaged waterproof layer can leave the mattress vulnerable even if the top fabric still looks clean.
Create a Practical Mattress Protection Routine
For adults experiencing frequent incontinence, mattress protection works best as part of a consistent nighttime routine.
Keep clean bedding and a spare waterproof cover nearby so accidents can be handled quickly. After removing soiled bedding, check the mattress underneath for moisture before making the bed again.
Regularly washing and inspecting the mattress cover helps protect the mattress while making everyday incontinence care more manageable for both individuals and caregivers.
