A Casper mattress should usually be cleaned with a vacuum and gentle spot cleaning. Do not soak the mattress, put it in a washing machine, or remove its zippered cover unless the care instructions for your exact model clearly say the cover is removable and washable.
Casper’s current guidance for many mattresses is to leave the cover in place, clean affected areas with water and mild detergent, and let the mattress air-dry fully before replacing the bedding. Some models sold in certain regions may have a washable top cover, so check the mattress label and current product guidance before starting.
Brand-specific care differs, so use the Purple mattress cleaning steps rather than applying Casper instructions to a different cover and material system.
What You Will Need
Gather a few simple supplies:
- A vacuum with an upholstery attachment
- Two or three clean white cloths
- Cold or lukewarm water
- A small amount of mild detergent
- A bowl
- Dry towels
- A fan, if available
- Baking soda for light odors, if allowed by your model’s care guidance
Use white cloths when possible. A brightly colored cloth may transfer dye to the mattress cover.
Check Your Casper Mattress Model First
Before cleaning, find the mattress label or look up the current care instructions for your exact Casper model.
This matters because cover designs can differ. Many Casper mattresses have a zipper, but the zipper does not automatically mean the cover is meant to be removed. Casper explains that the cover protects important mattress parts and should not be taken off on models with a non-removable cover.
Some Casper guidance outside the United States lists models with a machine-washable top portion. Other models must be spot cleaned without removing the cover.
When the label and online advice do not match, follow the current instructions supplied for your mattress or contact the manufacturer.
How to Clean a Casper Mattress Step by Step
1. Remove All Bedding
Take off the:
- Sheets
- Pillowcases
- Blankets
- Comforter or duvet
- Mattress protector
- Mattress pad or topper
Wash each item according to its own care label. Do not assume the mattress protector and mattress cover have the same washing instructions.
Casper’s guidance for its mattress protectors commonly calls for cold water and low-temperature drying, but the care label on your protector should be your main guide.
2. Vacuum the Mattress
Use a clean upholstery attachment to vacuum the top and sides of the mattress.
Move slowly over:
- Seams
- Tufted areas
- Edges
- The area near the head of the bed
- Spots where pets sleep
- Crumbs or visible debris
Use light pressure. There is no need to push the vacuum attachment hard against the foam.
For regular cleaning without stains, vacuuming may be all the mattress needs. Casper includes surface vacuuming as part of its general mattress-cleaning process.
3. Blot Fresh Spills
If the spill is still wet, press a clean, dry towel against it.
Lift the towel and repeat with a dry section until you have absorbed as much liquid as possible. Do not scrub. Scrubbing can spread the spill and press moisture farther into the cover.
Work from the outside of the wet area toward the center. This helps keep the spot from growing.
4. Mix a Mild Cleaning Solution
Add a small amount of mild detergent to a bowl of water. You only need enough detergent to make a weak solution.
Dip a clean cloth into the water and wring it out well. The cloth should feel damp, not dripping wet.
Casper recommends spot cleaning affected areas with water and mild detergent. The company also warns against using too much liquid because the foam core can absorb it.
Test the solution on a small, less visible area before treating a larger stain.
5. Blot the Stain
Press the damp cloth lightly against the stain. Lift it instead of rubbing it back and forth.
Repeat with a clean part of the cloth. For a larger spot, work in small sections.
Do not pour the cleaning solution directly onto the mattress. A spray bottle can also release more liquid than expected, so apply the solution to the cloth first when possible.
6. Remove Detergent Residue
Dampen a second cloth with plain water and wring it out well.
Blot the treated area to pick up leftover detergent. Do not try to rinse the mattress by soaking it.
Then press a dry towel over the area to absorb moisture.
7. Let the Mattress Dry Completely
Leave the mattress uncovered until the cleaned area is fully dry.
To help it dry:
- Open a window when weather allows.
- Run a fan across the mattress.
- Keep sheets and protectors off the bed.
- Allow air to move around the room.
- Keep children and pets away from the damp spot.
Do not remake the bed while the surface still feels cool or damp. Casper advises letting treated areas air-dry completely before replacing bedding.
Drying may take longer in a humid room or after a larger spill.
How to Freshen a Casper Mattress
For a mattress with no visible stain, start by vacuuming it and airing out the room.
A light layer of baking soda is sometimes used to absorb mild surface odors. Leave it on the dry mattress for several hours and vacuum it up thoroughly. Casper includes baking soda in some of its general mattress-cleaning guidance.
Before using baking soda, check your model’s current care instructions. Do not mix the powder with water on the mattress. Wet baking soda can be difficult to remove from fabric and foam.
A Casper mattress should usually be cleaned with a vacuum and gentle spot cleaning; it is usually better to clean a mattress mostly dry.
Strong perfume sprays are not a good substitute for cleaning. They may cover the smell without removing its source.
Cleaning Common Mattress Stains
Sweat and Body Oil Marks
Use the mild detergent method:
- Vacuum the mattress.
- Blot the mark with a barely damp cloth and mild detergent.
- Blot again with a cloth dampened with plain water.
- Press with a dry towel.
- Air-dry fully.
Older yellowing may not disappear completely. Mattress fabric and foam can also change color naturally with age and exposure to air.
Food and Drink Spills
Remove any solid pieces with a spoon or dull edge. Blot liquids with a dry towel before spot cleaning.
Avoid pushing crumbs into the seams. Vacuum the area after it is dry.
For colored drinks, begin with the mildest cleaning method. Strong stain removers may discolor the cover, so check the product label and Casper’s guidance before using one.
Urine Accidents
Remove wet bedding quickly and blot the mattress with dry towels. Do not scrub.
Because urine can soak deeply into foam, use very little cleaning liquid. A product made for fabric or upholstery may be useful, but it should be tested in a hidden area and checked against the mattress care instructions first.
Casper publishes a more involved urine-cleaning method, but it uses considerably more liquid than the company’s current mattress product guidance generally recommends. For a Casper mattress, take the cautious approach: avoid saturation and contact Casper support when the accident has soaked deep into the foam.
Pet Hair and Dirt
Vacuum the mattress slowly with an upholstery attachment. A clean lint roller can pick up hair left behind.
Pay extra attention to seams and the area near the foot of the bed. Wash the sheets and removable protector according to their care labels.
For homes with pets, a washable mattress protector makes routine cleanup easier.
What Not to Do
Do Not Remove the Cover Without Checking
A zipper is not proof that the mattress cover is washable. Many Casper mattress covers are meant to stay on the mattress.
Do Not Soak the Foam
Foam can hold moisture below the surface even when the cover feels almost dry. Use damp cloths rather than pouring or heavily spraying cleaner onto the bed.
Do Not Put the Mattress in a Washer
The mattress itself is not machine washable. Only wash removable accessories or cover sections that are clearly labeled as washable.
Do Not Use High Heat
Avoid hair dryers, heaters, irons, and other direct heat sources. Heat may affect the cover or foam.
A room fan is a gentler way to speed up drying.
Do Not Scrub Hard
Hard scrubbing may spread the stain, roughen the fabric, or force moisture deeper into the mattress.
Do Not Mix Cleaning Chemicals
Do not combine bleach, ammonia, vinegar, peroxide, or other cleaners. Use one mild method and follow the cleaner’s safety label.
Bleach and strong solvents should not be used unless the mattress manufacturer specifically permits them.
Do Not Sleep on a Damp Mattress
Wait until the mattress is completely dry. When necessary, use another bed or sleeping space for the night rather than covering a damp area with sheets.
How to Keep a Casper Mattress Cleaner
A removable mattress protector is the simplest first layer against spills, sweat, pet dirt, and everyday marks. Casper also recommends a stain- and water-resistant protector that can be removed and cleaned separately.
Other practical habits include:
- Washing sheets regularly
- Treating spills as soon as possible
- Vacuuming when you change seasonal bedding
- Keeping food and drinks away from the bed
- Using an extra protective layer on kids’ beds
- Checking the protector after pet accidents
- Letting bedding dry fully before putting it back on
- Rotating the mattress when the current model instructions recommend it
A guest-room mattress may need less frequent cleaning, but it should still be checked before visitors arrive. In a dorm room, RV, or small bedroom, a fan can help because airflow around the bed may be limited.
When a Stain Cannot Be Fully Removed
A faded mark does not always mean the mattress is still dirty. Some stains leave permanent discoloration after the residue and odor have been cleaned.
Stop adding cleaner when repeated treatment is making the mattress wetter without improving the mark.
Contact the manufacturer for guidance when:
- A large amount of liquid has soaked into the mattress
- The cover has been damaged
- The mattress still smells after it dries
- You are unsure whether the cover can be removed
- The care label is missing
- The stain involves a substance that needs special handling
- You see signs of ongoing moisture damage
Frequently Asked Questions
Can I remove and wash the cover of a Casper mattress?
Usually, no. Many Casper mattress covers are not meant to be removed, even though they have a zipper. Some models or regional versions may have a washable top section, so check the label and current instructions for your exact mattress.
Can I steam-clean a Casper mattress?
Steam cleaning is not part of Casper’s standard mattress care guidance. It introduces heat and a large amount of moisture, which can be difficult to remove from foam. Use gentle spot cleaning unless your exact model’s instructions specifically allow another method.
Can I use a carpet cleaner on a Casper mattress?
A carpet-cleaning machine can saturate the mattress. Casper advises using limited water and mild detergent because the foam core can absorb moisture. Hand spot cleaning is the safer beginner-friendly choice.
Can I use baking soda on a Casper mattress?
Baking soda may help with mild surface odors when the mattress is dry. Use a light layer, keep it dry, and vacuum it up completely. Check the current care guidance for your model before applying it.
How long should a Casper mattress dry after cleaning?
Leave it uncovered until the treated area is completely dry. The time depends on the size of the spot, room humidity, and airflow. A fan can help. Do not put sheets back on while the area still feels damp.
What detergent should I use?
Use a small amount of mild detergent without bleach or harsh solvents. Test it on a hidden area first and follow both the detergent label and the mattress care instructions.
How often should I clean my Casper mattress?
Vacuum it when you notice dust, crumbs, or pet hair, and spot clean spills right away. There is usually no need to wet-clean the full mattress on a fixed schedule. Regularly washing the sheets and mattress protector reduces the need for deeper cleaning.
Should I clean both sides of the mattress?
Vacuum any exposed surfaces that need cleaning, but do not flip the mattress unless Casper’s current instructions for your model say it is designed to be flipped. Many modern foam and hybrid mattresses have a specific top and bottom.
