A mattress protector accumulates a lot of bacteria and sweat over time, so you must clean it to work effectively and be hygienic. Because a fitted sheet is placed over a mattress protector, the protector should only be washed every one to two months (as opposed to every two weeks in the case of an adjustable fitted sheet). First and foremost, let's resolve the question of how often a mattress protector should be washed. A good rule of thumb for optimal mattress protection is to wash the mattress cover once a month.
Mattress protectors help extend the life of the mattress, so they should also be looked after. It is recommended to wash a mattress protector every two months. However, you may need to wash it more often if spills occur or if you allow pets to sleep in bed. How often you wash the mattress cover will vary depending on how often you change the sheets and if they have spilled.
Cleaning a cotton mattress protector is usually quite simple. Always check the care instructions label before washing it. In general, cotton mattress protectors can be washed in the washing machine and dried in the dryer. They should be cleaned approximately every 2-3 months depending on several factors, for example, whether or not pets are allowed to sleep in bed.
Wash the cotton mattress protector in the washing machine with a mild detergent in warm or cold water. Run a gentle cycle without too much detergent to prevent any soap residue from damaging the fibers. Dry it in the dryer at the lowest possible temperature and setting, and add a couple of dryer balls or even clean tennis balls to keep the mattress protector fluffy. Make sure the mattress is completely dry before making the bed to prevent mold or mildew from forming.
In general, you should wash removable mattress covers at least once every two months. However, you should also consider how often you use the mattress and its waterproof protector. Use a reusable shower head to rinse the mattress protector or lightly fill the tub with clean water, squeezing out the foam to remove the cleaning solution.
