How To Clean a Casper Mattress: Simple Steps and FAQs

If you’re searching for “How To Clean a Casper Mattress”, you’re usually dealing with spills, stains, or just everyday buildup. This guide walks through practical, mattress-safe methods to freshen your bed, remove common stains, and understand what to avoid so you don’t damage the foam or cover.

What should I know before cleaning a foam mattress?

Foam mattresses are made of porous materials that can absorb liquids quickly. That means:

  • No soaking or saturating the mattress
  • No harsh chemicals or bleach, which can break down foam
  • No machine washing or drying the mattress itself

Most foam mattress covers are not designed to be heavily scrubbed or machine washed either, as this can cause shrinking, warping, or damage to zippers and seams. Always check any care tag or documentation that came with your mattress before starting.

How To Clean a Casper Mattress: Basic Routine Cleaning

Step 1: Strip and air out the mattress

Remove all bedding, including protectors and toppers. Let the mattress air out for 30–60 minutes if possible. This helps mild odors disperse and makes surface cleaning easier.

Step 2: Vacuum the surface

Use a handheld or upholstery vacuum attachment to remove dust, hair, and crumbs.

  • Work in slow, overlapping passes
  • Pay attention to seams and edges
  • Avoid pressing too hard to keep from damaging the foam beneath

Regular vacuuming every few months can help keep the surface fresher between deeper cleans.

Step 3: Deodorize with baking soda

For general odor and freshness:

  1. Sprinkle a light, even layer of baking soda over the surface.
  2. Let it sit for at least 30–60 minutes; longer (a few hours) helps more noticeable odors.
  3. Vacuum thoroughly to remove all residue.

Baking soda helps absorb smells without soaking the mattress or adding moisture.

How do I clean spills and fresh stains?

When people ask How To Clean a Casper Mattress, they’re often dealing with a fresh spill. Acting quickly makes a big difference.

Step 1: Blot, don’t rub

  • Use a clean, dry cloth or paper towels
  • Gently press to absorb as much liquid as possible
  • Avoid scrubbing, which can push moisture deeper into the foam

Step 2: Spot clean with mild soap solution

Mix a small amount of mild liquid soap with cool water. The solution should be lightly soapy, not foamy or heavy.

  • Dampen (don’t soak) a clean cloth in the solution
  • Blot the stained area gently
  • Follow with another damp cloth with plain water to remove soap residue

The goal is to slightly dampen the surface, not wet the mattress through.

Step 3: Dry thoroughly

  • Press a dry towel onto the area to absorb extra moisture
  • Allow the mattress to air dry completely before putting sheets back on
  • If needed, use a fan to speed up drying (avoid direct high heat)

How do I tackle tougher stains (like drinks or body fluids)?

For more stubborn stains, you can still use gentle, household methods.

Mild cleaning approaches

You can:

  • Start with the same mild soap and water method
  • Repeat the process a few times rather than using stronger chemicals
  • Always work from the outside of the stain inward to avoid spreading

If the mattress has a removable cover, some covers may be designed for spot cleaning only. Use a lightly damp cloth and mild detergent, then blot dry. Avoid soaking the cover, as moisture can reach the foam underneath.

What should I avoid when cleaning a foam mattress?

To protect the comfort and structure of your mattress, avoid:

  • Bleach or strong chemical cleaners
  • Steam cleaning, which can drive moisture deep inside
  • Soaking the mattress or using large amounts of water
  • Harsh scrubbing brushes or abrasive pads
  • Machine washing or drying the mattress

These can cause foam breakdown, lingering odors from trapped moisture, or cover damage.

How often should I clean and maintain it?

For general upkeep:

  • Vacuum every 1–3 months
  • Deodorize with baking soda a few times a year, or as needed
  • Spot clean spills immediately to reduce staining

Using a washable mattress protector can significantly limit how often you need to deal with direct stains on the mattress itself.
