Can You Clean a Purple Mattress Cover? What’s Safe and What Ruins It

[Published: August 16, 2026 | Last updated: August 16, 2026]

TL;DR

You can spot clean a Purple mattress cover, but Purple’s own support team says not to remove it or machine wash it (Purple Support, 2026).
Blot spills immediately, then treat the spot with a mild detergent or enzyme cleaner and a damp cloth (Purple Support, 2026).
The cover is heavy in spandex, so machine washing risks shrinking it to the point it won’t zip back on (NapLab, 2026).
If you own a separate Purple Mattress Protector, that piece is fully machine washable in cold water on low tumble dry (Purple Support, 2026).
Skip fabric softener, bleach, and the iron – all three can break down the cover’s stretch fabric.

Can You Wash a Purple Mattress Cover?

No. Purple’s official care instructions say to spot clean the cover and skip the washing machine entirely (Purple Support, 2026). The zippered cover looks removable, and it does unzip, but Purple doesn’t design it for a full wash cycle.

The reason comes down to the fabric. The cover is knit with a high percentage of spandex to stretch over the foam layers underneath. Put that much spandex through a washing machine and dryer, and it can shrink enough that it no longer fits back over the mattress (NapLab, 2026).

If your goal is a cover you can toss in the machine, that’s what the separate Purple Mattress Protector is for – not the cover that ships on the mattress itself.

How to Spot Clean a Purple Mattress Cover

Spot cleaning is the method Purple recommends, and it works well for sweat, small spills, and everyday grime. Here’s the process straight from Purple’s support documentation (Purple Support, 2026).

Step 1: Blot, don’t rub. For fresh liquid spills, press a clean, dry cloth onto the area to absorb as much moisture as possible. Rubbing pushes the liquid deeper into the fabric and spreads the stain.

Step 2: Apply a cleaning solution. Once no more liquid transfers to the cloth, wipe the stained area with a mild detergent or an enzyme cleaner. Enzyme cleaners work best on organic stains like sweat, urine, or food.

Step 3: Rinse with a damp cloth. Dampen a clean cloth with warm water and wipe over the treated spot to remove any leftover detergent residue.

Step 4: Air dry completely. Let the cover air dry before putting bedding back on. Avoid direct sunlight, since UV exposure can damage the material over time (Purple, 2025).

What Not to Do to a Purple Mattress Cover

Getting the fabric wrong once can mean living with a damaged cover for years. These are the mistakes to avoid.

Don’t machine wash or machine dry it. Purple explicitly advises against this – the spandex content makes the cover prone to shrinking (Purple Support, 2026).
Don’t iron it. Heat from an iron can melt or warp the synthetic fibers in the cover.
Don’t use bleach. Bleach breaks down spandex fibers and can discolor the fabric permanently.
Don’t use fabric softener if you’re washing a separate mattress protector alongside it. Softener coats fibers and can reduce a protector’s breathability and any waterproof backing it has.
Don’t scrub stains aggressively. Rubbing spreads the stain and can wear down the fabric weave faster than blotting.

Purple Mattress Cover vs. Purple Mattress Protector: Cleaning Differences

These two pieces get confused often, but they’re cleaned in completely different ways.

Item	What It Is	How to Clean It
Purple Mattress Cover	The zippered fabric layer built into the mattress	Spot clean only – no machine wash (Purple Support, 2026)
Purple Mattress Protector	A separate, optional layer sold to protect the mattress	Machine wash cold, tumble dry low (Purple Support, 2026)
Purple Pillow Cover	Zippered cover on Purple pillows	Machine wash cold, separately, tumble dry low (Purple Support, 2026)

If you own a Purple Mattress Protector, that’s the piece you can strip and throw in the wash on a normal basis. The built-in mattress cover is the one that needs the gentler spot-clean approach.

How Often Should You Clean a Purple Mattress Cover?

Spot clean stains as soon as they happen, and give the whole cover a general refresh every two to three months. Vacuuming the surface with an upholstery attachment removes dust and skin cells that build up between deeper cleanings. Sprinkling baking soda over the cover, letting it sit for 15 to 20 minutes, then vacuuming it off helps neutralize odors without any liquid at all (Purple, 2025).

Frequently Asked Questions About Cleaning a Purple Mattress Cover

Can you clean a Purple mattress cover?

Yes, but only by spot cleaning. Purple’s support team advises against removing the cover for a full wash, since machine washing and drying can shrink the spandex fabric (Purple Support, 2026).

What happens if you wash a Purple mattress cover in a washing machine?

The cover can shrink to the point where it no longer stretches back over the mattress. The high spandex content that gives the cover its stretch is also what makes it vulnerable to machine washing and drying (NapLab, 2026).

What’s the best cleaner for a Purple mattress cover stain?

A mild detergent or an enzyme cleaner works well. Apply it after blotting the spill, then wipe the area with a damp cloth to remove residue (Purple Support, 2026).

Is the Purple Mattress Protector the same as the mattress cover?

No. The cover is the built-in fabric layer on the mattress itself and should only be spot cleaned. The protector is a separate accessory that’s fully machine washable in cold water (Purple Support, 2026).

Can you remove the Purple mattress cover to clean it separately?

The cover unzips, but Purple’s instructions say not to remove it for washing. Removing it doesn’t change the spot-clean-only recommendation, and there’s added risk of struggling to get it back on tightly once it’s off (Amazon Customer Q&A, 2020).

Key Takeaways

Spot clean the Purple mattress cover with a mild detergent or enzyme cleaner – never machine wash it.
Blot spills immediately and let the cover air dry away from direct sunlight.
A separate Purple Mattress Protector, if you own one, is machine washable and handles the heavy-duty cleaning job instead.
Vacuum and deodorize with baking soda every two to three months to keep the cover fresh between spot cleanings.
