How to Clean a Waterproof Mattress Protector (Without Ruining the Waterproofing)

The most important part of a waterproof mattress protector is the invisible polyurethane membrane on the back. If washed incorrectly, this membrane can blister, melt, or peel, destroying its waterproofing capabilities.

Washing Instructions

• Wash separately or with soft items (like bedsheets). Do not wash with jeans, towels, or items with zippers that could scratch the waterproof backing.
• Use the wash temperature specified on the protector’s care label.
• Use a small amount of mild detergent.

Drying Instructions (CRITICAL)

Never tumble dry on high heat!

Excess heat can damage some waterproof backings. Use only the drying method and temperature permitted on the label. Dry completely before refitting, then inspect for peeling, cracks, or damaged seams.

When to Replace

Check the warranty terms supplied with your product. Assess replacement if the barrier fails, the backing peels, or the fit no longer works. A fixed age alone does not establish that a protector needs replacing.
