How to Wash a Waterproof Blanket

A waterproof blanket is a lifesaver. Spills, sweat, pet mess, all handled. But cleaning it? That's where most people slip up.

Here's the thing. These blankets aren't like your regular throw. Treat them the same way, and you risk damaging the inner layer that actually keeps moisture out.

And once that layer is compromised, it's done. No fixing it.

So if you want your blanket to last, you need to wash it the right way from the start.

 

Why Waterproof Blankets Need Different Care

Most waterproof blankets have multiple layers. There's the soft outer fabric you feel, and then a hidden waterproof barrier underneath.

That barrier is delicate. Heat, harsh detergents, and rough washing can weaken it over time.

Honestly, that's where most damage happens.

And once it starts peeling or cracking, leaks follow. Every single time.

 

Check the Care Label First

Before anything else, look at the tag.

It sounds basic. But it matters.

Different brands use slightly different materials, and the care instructions can vary more than you'd expect (even between two blankets that look identical).

So don't guess. Follow what's written. The same rule applies when washing a cooling blanket - the care label is always the first step before anything else.

 

How to Wash a Waterproof Blanket Properly

 

1. Use Cold or Warm Water

Hot water is a problem here.

It can break down the waterproof layer faster than you think. Stick with cold or warm settings to stay safe.

 

2. Choose a Mild Detergent

Skip the heavy-duty stuff.

Go for a gentle detergent without bleach or fabric softeners. Those additives can mess with the waterproof coating and reduce effectiveness over time.

Less is more.

 

3. Select a Gentle Cycle

Rough cycles are too aggressive.

Use a delicate or gentle setting so the blanket doesn't get twisted or stretched unnecessarily.

Your machine matters here.

 

4. Avoid Fabric Softeners

They might make regular blankets feel softer, but here, they do the opposite of what you want.

They leave a residue that interferes with water resistance. Not worth it.

 

5. Rinse Thoroughly

Any leftover detergent can affect performance.

Run an extra rinse cycle if needed. It helps remove buildup and keeps the blanket working like it should.

 

Drying a Waterproof Blanket Safely

Drying is where people mess up most.

 

Air Dry When Possible

The safest option is air drying.

Hang it up or lay it flat. It takes longer, sure, but it protects the waterproof layer from heat damage.

 

Use Low Heat If Tumble Drying

If you're using a dryer, keep it on low heat.

High temperatures can warp or weaken the inner lining. And once that happens, you'll notice.

Quick.

 

Mistakes to Avoid

Some habits will shorten your blanket's life fast.

• Using hot water
• Adding bleach or harsh chemicals
• Drying on high heat
• Skipping the rinse cycle
• Washing too frequently

Look, you don't need to wash it after every use. Only when it actually needs it.

 

How Often Should You Wash It?

That depends on how you use it.

For everyday use, once every couple of weeks is enough. If it's dealing with pets, spills, or sweat, you might need to clean it more often.

Trust your judgment.

If it smells or looks dirty, wash it. The same washing frequency applies to cooling blankets - every two to three weeks keeps both types performing at their best.

 

Keep It Working Longer

Taking care of your waterproof blanket isn't complicated.

But it does require a bit of attention.

Small habits make a difference. Using the right settings. Avoiding heat. Choosing gentle products.

Do that, and your blanket will last much longer.

And still do its job. Browse our full range of waterproof blankets built to last with easy-care materials that stand up to regular washing.

 

Final Thoughts

A waterproof blanket is built to handle mess. But it still needs proper care.

Wash it wrong, and you'll lose what makes it useful. Wash it right, and it'll keep protecting your bed, couch, or wherever you use it for a long time.

So don't rush it.

Do it properly. It's worth it.

 

FAQs 

 

Q1: Can you put waterproof blankets in the dryer?

 

 Yes - but only on a low heat setting. High heat is the biggest threat to a waterproof blanket because it warps and weakens the inner waterproof lining that keeps moisture from passing through. Once that lining is damaged by heat it cannot be repaired. If your dryer does not have a low heat or delicate setting, air drying is the safer option. Hang it up or lay it flat and let it dry naturally. It takes longer but it protects the blanket completely. Always check the care label on your specific blanket before putting it in the dryer as some materials require air drying only.

 

Q2: Is it okay to wash a 15 lb blanket in a washer?

 

It depends on your washing machine's capacity. A standard home washing machine typically handles blankets up to 12 to 15 pounds but only if the drum is large enough for the blanket to move freely during the cycle. If the blanket is packed too tightly it will not rinse properly and the spin cycle puts uneven stress on the fabric and waterproof barrier. If you are unsure whether your machine can handle the weight comfortably a laundromat with a large-capacity front-loading machine is a safer option. Always use a gentle cycle and cold or warm water regardless of machine size.

 

Q3: Can you machine wash waterproof fabric?

 

 Yes - waterproof fabric is machine washable in most cases. The key is using the right settings. Always select a gentle or delicate cycle with cold or warm water. Avoid hot water as it breaks down the waterproof coating over time. Use a mild detergent without bleach or fabric softeners - both leave residue that interferes with water resistance. Run an extra rinse cycle to make sure no detergent remains in the fabric. Check the care label before washing as some waterproof fabrics have specific instructions depending on the coating or material used.

 

Q4: Can I put a sopping wet blanket in the dryer?

 

 Yes - but wring out or spin out as much excess water as possible first. Putting a heavily saturated blanket straight into the dryer adds significant weight and strain on the drum, and the drying time becomes much longer. If your washing machine has a spin cycle use it to remove most of the water before transferring to the dryer. Once in the dryer use a low heat setting only. For waterproof blankets specifically a sopping wet blanket on high heat is a fast way to damage the inner lining - low heat and patience is always the right call.
