FAQ
What washer setting should I use for a mattress protector?
Use a normal or gentle cycle with warm or cold water and mild detergent. Skip bleach and fabric softener; both can degrade the waterproof membrane.

Tumble dry a waterproof mattress protector on low heat or air dry it. High heat can melt or crack the waterproof backing, so remove it promptly and never use a hot cycle.
