How to Wash a Waterproof Sex Blanket: The Complete Care Guide

how to wash waterproof sex blanket care guide

A waterproof blanket is an investment worth protecting. With proper care most quality blankets like the Pound Pad last for years with no degradation in waterproofing or softness. With improper care, the waterproof barrier can delaminate and the top surface can pill or roughen. Here is exactly how to care for yours.

Machine Washing: The Right Settings

Always wash on a cold or cool gentle cycle. Hot water weakens the adhesive bond between the fabric and the waterproof layer over time. Use a mild detergent without bleach or fabric softener. Bleach degrades the TPU or polyurethane barrier faster than almost anything else. Fabric softener coats the fibers of the top surface and can reduce the softness paradoxically by leaving a waxy residue that mats the fibers down.

Wash the blanket alone or with other soft items of similar weight. Do not wash it with heavy items like jeans or towels which can cause mechanical abrasion to the surface.

The Pound Pad is rated for repeated machine washing without losing waterproofing. See current price on Amazon.

Drying: Do It Right

Tumble dry on low heat or air dry flat. High heat is the single most damaging thing you can do to a waterproof blanket. It can melt or warp the waterproof barrier layer, causing cracking, bubbling, or delamination that is permanent. Low heat is fine for most quality blankets and will dry them completely without damage. Air drying flat is the safest option if you want maximum blanket longevity.

Do not iron. Do not dry clean. Both will damage the waterproof layer.

Spot Cleaning Between Washes

For minor cleanup between full washes, use a damp cloth with mild soap on the top surface. The waterproof layer underneath means spills can be wiped from the top without soaking through. For blood stains specifically, rinse in cold water as soon as possible. Cold water prevents blood proteins from setting. Hot water sets the stain and makes it much harder to remove.

Storage

Store the blanket folded in a cool dry place out of direct sunlight. UV exposure can degrade the waterproof barrier over time. Do not store it compressed under heavy objects for extended periods as this can mat the top surface. A drawer, shelf, or storage bag works well.

Frequently Asked Questions

Can you machine wash a waterproof sex blanket?

Yes. Use a cold or cool gentle cycle with mild detergent, no bleach, and no fabric softener. Wash alone or with similar lightweight items.

What dryer setting should I use for a waterproof sex blanket?

Low heat only, or air dry flat. High heat can warp, crack, or delaminate the waterproof barrier layer permanently.

Can I use fabric softener on a waterproof sex blanket?

No. Fabric softener leaves a waxy residue that mats the fibers and can actually make the surface feel rougher over time. Skip it entirely.

How do I remove blood stains from a sex blanket?

Rinse immediately in cold water, not hot. Cold water prevents blood proteins from setting. Then wash normally on a cold cycle. Act quickly for best results.

How long does a waterproof sex blanket last with proper care?

With proper care (cold wash, low heat dry, no bleach or fabric softener) a quality blanket like the Pound Pad should last 3 to 5 years or more of regular use without loss of waterproofing.
