First of all, let's solve the question of how often a mattress protector is washed. A good rule of thumb for maximum mattress protection is to wash the mattress cover once a month. Mattress protectors help to extend the life of the mattress and should therefore also be cared for. 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 be in bed. You should clean your mattress at least twice a year. Despite layers of sheets and mattress protectors, dust, dirt, oils, skin cells, and other debris can reach the mattress itself. Using some baking soda and a vacuum is usually all it takes to clean a mattress.
You can wash the mattress protector every two months by following the rule of thumb. However, it's not a hard and fast rule. The frequency of washing depends on several factors and situations. Below, we share a brief description of it.
