Can You Machine Wash a Car Cover? Here’s the Safe Way to Do It

ByDaniel Brooks Car Cover

⚡ Quick Answer

Yes, most car covers can be machine washed, but only if the care tag says so, and only in a front-loading machine with no center agitator. Top-loading machines with an agitator can tear the fabric and ruin the water-resistant coating.

Before you wash a car cover:

  • Check the tag: Not all fabrics allow machine washing.
  • Use a front loader: No center agitator, or the fabric can tear.
  • Skip the extras: No fabric softener, bleach, or dryer heat.

A car cover works hard. It takes on rain, dust, tree sap, and bird droppings so your paint doesn’t have to. Daniel Brooks has watched plenty of covers turn into stiff, dirt-caked “old rags” simply because owners never washed them, and it shortens the life of the fabric fast.

The good news: cleaning a cover is easy once you know the rules. Some covers can go straight into the washing machine. Others need a gentle hand wash instead. Here’s how to tell the difference and get it right the first time.

📌 Key Takeaways

  • →Machine washability depends entirely on the cover’s fabric and its care label.
  • →Top-load agitators are the most common cause of torn or shredded covers.
  • →Fabric softener strips away a cover’s water-resistant coating.
  • →Extra-large covers for SUVs and trucks usually need a commercial-size machine.

Is Your Car Cover Actually Machine Washable?

Check the care tag first. It’s usually sewn into a seam near the mirror cutout or the driver’s side hem. This one step saves the most heartbreak.

Most modern woven fabrics, like polyester and Sunbrella-style blends, tolerate machine washing well. Vinyl and some non-woven or specialty materials often can’t. They need a careful hand wash instead, since spinning can crack or warp them.

⚠️ Warning

Never use a top-loading washer with a center agitator. The spinning post catches and tears cover fabric, and several manufacturers explicitly warn against it.

How to Machine Wash a Car Cover, Step by Step

If your tag confirms machine washing is safe, use a front-loading machine, ideally a large commercial one at a laundromat if your cover is oversized. Here’s the process.

🔢 Step-by-Step: Machine Washing a Car Cover

  1. 1

    Shake out loose dirt

    Remove the cover and shake it, or vacuum on low power, to clear dust before washing.

  2. 2

    Pre-treat tough stains

    Rub bird droppings with a vinegar-detergent mix, and tree sap with a little denatured alcohol.

  3. 3

    Load and set the cycle

    Use cold or lukewarm water, mild bleach-free detergent, and the gentle or delicate cycle.

  4. ✓

    Rinse twice and air dry

    Run an extra rinse to clear all detergent, then lay flat or drape it over the car to air dry.

When to Hand Wash Instead

Hand washing is the safer default whenever you’re unsure about the fabric, and you don’t even need to remove the cover from the car.

📋 Hand-Washing Basics

  • Rinse first: Hose down the cover to remove loose grit before scrubbing.
  • Mild soap only: A bucket of water with a mild, bleach-free detergent works well.
  • Flip and repeat: Wash, rinse, then turn the cover inside out and do it again.

What Most People Get Wrong About Washing a Car Cover

Most owners assume any washing machine will do. In reality, a standard top-loader with a center agitator is the top cause of torn or worn-through covers.

Many also reach for fabric softener out of habit. That’s a mistake. Softener coats the fibers and breaks down the water-resistant finish, so rain starts soaking straight through.

Finally, people skip the second rinse. Leftover detergent residue also weakens water resistance over time, so always run that extra rinse cycle.

Conclusion

Most car covers can go in the washing machine, but only in a front loader on a gentle cycle, and only if the tag agrees. Skip the agitator, the softener, and the dryer, and your cover will keep protecting your paint for years.

Do this now: check your cover’s care tag before your next wash day, so you know exactly which method it’s rated for.

Frequently Asked Questions

Can I put a car cover in the dryer?

No, unless the manufacturer specifically says the fabric allows it. Dryer heat can shrink, warp, or damage the coating on most car cover materials, so air drying is the safer default.

How often should I wash my car cover?

Every few months for regular use, or sooner if it collects visible dirt, sap, or bird droppings. A dirty cover holds moisture against the fabric, which weakens water resistance and can transfer grime to your paint.

Can I wash a car cover with the car underneath it?

Yes, for hand washing. Leave the cover on the car, hose it down, scrub with mild soap and a sponge, then rinse thoroughly. This is the easiest method for large or bulky covers.

What removes bird droppings from a car cover?

Soak the spot in warm water with detergent and a splash of vinegar, then rub with a cloth until it lifts. A bird-dropping remover spray also works well before washing.

Does washing ruin a car cover’s water resistance?

Washing itself doesn’t, but fabric softener and leftover detergent do. Use a bleach-free, mild detergent, skip the softener, and rinse twice to protect the coating.

Can I use bleach on a car cover?

No. Bleach breaks down cover fabric and its protective coatings. Stick to a mild, bleach-free detergent for both hand and machine washing.

How do I fold a car cover after washing?

Make sure it’s completely dry, then fold it on top of the car rather than the ground to avoid picking up abrasive dirt. Roll or fold it three to four times and store it in its bag.
