Mattress protectors are crucial to safeguarding your bed against spills, stains, dust mites and more, and naturally collect bacteria, sweat and other undesirable elements over time. Make sure you’re sleeping in a safe and hygienic environment by finding out how often to wash your mattress protector below.

General use

Seeing as your protector goes underneath your fitted sheet, you don’t need to wash it as often – assuming there are no stains or other accidents which may have leaked through your sheet. While all standards are different, your mattress protector can probably go as long as 4 weeks and still remain safe and clean.

Guest bedrooms

Naturally, you’ll want to wash your protector before and after someone stays in your guest room. However, if you don’t have guests for a while, you should still clean it to get rid of any dust that may have built up. To freshen up your sleeping space and to ensure a dust mite-free environment for your guests, make sure you wash your protector every 4 weeks.


If you suffer from allergies, your mattress might be part of the problem. This warm environment is the perfect breeding ground for dust mites, the most common cause of allergic reactions. A Protect-A-Bed mattress protector will stop them from breeding in your bed, and should be washed every 4 weeks to prevent any build-up of allergens. With dust mites, the cause of allergic reactions comes from their waste products. The dust mite life cycle is around 1 month, so washing every 4 weeks will effectively create a non-allergenic environment and ensure a safe sleeping space.
After you’re sick

When you have a cold or flu, your mattress protector will inevitably soak up some of the bacteria that caused your illness. As soon as you’re feeling better, wash your protector along with all your bed linen to ensure that you don’t spread your illness to anyone else in the house.

After a spill

Accidents happen, and you may inadvertently spill food or liquids onto your bed. A good protector, such as Protect-A-Bed’s range, will be 100% waterproof, so there is no chance of staining your bed. However, to keep your sleeping environment nice and clean, wash your protector and bed linen as soon as anything is spilled on your bed.
