How To Wash Casper Mattress Cover: Simple Care Guide & FAQs

If you’re searching for “How To Wash Casper Mattress Cover,” you’re likely wondering whether you can toss it in the washer, how often to clean it, and how to avoid damaging your mattress. This guide walks through what to do, what to avoid, and how to keep your cover fresh for the long term.

Is the Casper mattress cover machine-washable?

In most cases, the entire mattress cover is not meant to be machine-washed. Many modern foam mattresses use covers that are spot-clean only, especially if they have zippers, textured panels, or special fire-retardant layers attached.

Because designs and materials change over time, the first and most important step in answering “How To Wash Casper Mattress Cover” is to:

  • Check the care tag sewn into the cover
  • Review any care instructions that came with your mattress

Those instructions override any general advice. If the tag says “spot clean only,” do not machine wash or dry the cover.

How do I safely clean a Casper mattress cover?

If your cover is labeled spot clean only, follow this general process:

  1. Remove bedding
    Take off sheets, protectors, and any toppers.

  2. Vacuum the surface
    Use a hand vacuum or upholstery attachment to remove dust, crumbs, and loose debris from the cover.

  3. Mix a mild cleaning solution

    • Cool or lukewarm water
    • A small amount of gentle, liquid detergent (no bleach, no harsh chemicals)

  4. Spot clean stains

    • Lightly dampen a clean white cloth with the solution
    • Blot the stained area—do not scrub aggressively, as this can damage fibers or push moisture into the foam
    • Use a second cloth dampened with plain water to blot away detergent residue

  5. Dry thoroughly

    • Blot with a dry towel to absorb excess moisture
    • Allow the mattress to air-dry completely before putting bedding back on
    • Keep the area well-ventilated and avoid direct heat sources like hairdryers on high heat

For many users asking How To Wash Casper Mattress Cover, this spot-clean + vacuum approach is the safest default when the cover is not machine-washable.

What if my Casper mattress cover has a zipper?

A zipper on the cover can be confusing. It often exists so the manufacturer can assemble or inspect the mattress, not necessarily so you can wash the cover in a machine.

  • Do not assume a zippered cover is removable for washing.
  • If the tag does not clearly allow machine washing, leave the cover on and treat it as spot-clean only.

If the care instructions do say the cover (or a specific part of it) is machine washable, follow them closely regarding water temperature, cycle type, and drying method.

Can I put the Casper mattress cover in the dryer?

When people ask “How To Wash Casper Mattress Cover,” drying is just as important as washing:

  • If your cover is spot clean only, it generally should not go in the dryer at all.
  • For removable, machine-washable covers (when clearly allowed on the care tag):
    • Use low heat or air-dry settings
    • High heat can cause shrinkage, warping, or damage to elastic and fibers
    • Make sure the cover is completely dry before placing it back on the mattress

When in doubt, air drying is usually the gentlest option.

How often should I clean a Casper mattress cover?

Frequency depends on spills, stains, and general use. A practical routine is:

  • Weekly or biweekly: Wash sheets and any mattress protector you use
  • Every few months:
    • Vacuum the mattress cover surface
    • Spot clean any marks or stains
  • Immediately: Address spills or accidents as soon as they happen to reduce staining and odors

Many sleepers find that using a separate, washable mattress protector keeps the original cover cleaner and reduces the need for frequent deep cleaning.

What should I avoid when cleaning a Casper mattress cover?

To help your cover last, avoid these common mistakes:

  • No bleach or harsh chemicals – They can weaken fabric and discolor it.
  • No soaking the mattress – Excess moisture can reach the foam and be slow to dry.
  • No high-heat drying – This may shrink or damage the cover.
  • No rough scrubbing – This can fuzz, pill, or tear the fabric.

Keeping cleaning gentle and minimal is usually best.

Does washing the mattress cover affect the mattress itself?

If water or cleaning solution seeps through the cover into the foam, it can:

  • Take a long time to fully dry
  • Leave the mattress feeling damp or musty
  • Potentially affect comfort if not dried thoroughly

That’s why light spot cleaning, careful blotting, and full air-drying are key parts of any safe approach for How To Wash Casper Mattress Cover.
