Some techniques for cleaning a mattress include vacuuming with an upholstery brush, using an upholstery shampoo or homemade dry suds to remove stains, and flipping the mattress if recommended by the manufacturer. Rotate the mattress from head to toe seasonally.
Because mattresses may collect skin flakes, dust and dust mites, vacuum them on a regular basis. After removing the bedding, vacuum the top and sides of the mattress with an upholstery brush attachment.
To clean stains, use an upholstery shampoo as instructed on the bottle. Dry suds are also effective for mattress cleaning. To make dry suds, place 1/4 cup of dishwashing liquid in a mixing bowl, turn on the mixer and add 1 teaspoon of water at a time. This causes a soapy foam to form on top; use that foam to scrub the mattress with a sponge or soft brush. Avoid wetting the padding underneath the stain, and do not put the bedding back on the mattress until the area is dry.
Some mattress manufacturers recommend flipping the mattress over on a seasonal basis. Some mattresses, such as those with a pillow-top, should not be flipped, so it is important to check the manufacturer's instructions before doing so.
