Egg crate foam mattresses can be cleaned in less than an hour with this simple process. Freshen your sleep space using a vacuum, a spray bottle, some detergent and water.
Remove the dirt
Take off any bedding from the egg crate, and shake it out to loosen excess dirt. Use a vacuum fitted with a small attachment to carefully remove the dirt from the mattress. Vacuum both sides of the egg crate for a thorough cleaning.
Wash the egg crate
Fill a spray bottle with water and a small amount of laundry detergent to create a solution that is 25 percent detergent and 75 percent water. Spray the mattress all over, making sure to spray both sides. Allow the egg crate to soak in the cleaning solution for 30 to 60 minutes.
Rinse the egg crate
Take the mattress into the shower or use a hose to spray it thoroughly with clean water. Make sure all the cleaning solution is removed.
Dry the egg crate
Fold the egg crate in half and press out any excess water. Remove the remaining water by using a wet/dry vacuum or allowing the mattress to lay out and dry in the sun for several hours.
