Problem: Article: Check your mattress periodically for stains and clean them right away when you notice one. This will help to prevent them from setting in and keep your mattress cleaner. Any time you suspect your mattress might have a stain, check under the sheets and clean it right away. Lightly spray the mattress with vinegar and sprinkle a small amount of baking soda on the stain. Allow the mixture to sit for a couple hours. Scrape off the baking soda with a butter knife or flat piece of plastic. Vacuum up the baking soda after it has dried.  Dirt stains are not only unsightly, but they can be a breeding ground for bacteria and other health problems. For tougher stains, consider using general upholstery cleaner or other solutions intended for use on mattresses. Make sure to follow the directions and do not oversaturate the mattress. Combine 3 tablespoons of baking soda and 8 fluid ounces (240 mL) of hydrogen peroxide with a half teaspoon of dish soap. Lightly dab the solution on the urine stain. Avoid soaking the mattress with your solution. Allow the area to dry.  Urine is one of the most common stains on mattresses – especially on mattresses used by children. Not only does urine stain mattresses, but it leaves a nasty odor that is hard to get rid of. If the stain is still visible, combine 3 tablespoons of laundry powder and 1 tablespoon (14.8 ml) of water. Spread this on the stain and allow it to sit for half an hour. Then, remove the paste with a knife or thin flat piece of plastic. Vacuum to remove any residue. Combine 2 fluid ounces (59 mL) of hydrogen peroxide and 1 tablespoon (14.8 ml) each of dish soap and table salt. Spread the concoction over the stain and let it sit. Scape the remaining residue off with a butter knife or thin piece of plastic.  While not as common as urine, blood stains on mattresses are not that rare. But while blood stains lack the odor of urine stains, they’re often harder to remove. If the stain is still visible, lightly dab it with a clean white cloth that has been moistened with hydrogen peroxide. Moisten a clean white cloth with cleaning ammonia and dab the stain lightly. Wipe the area again with a clean white cloth.  Ventilate the room. Avoid using too much ammonia or any other liquid on your mattress. Perhaps the toughest stain to remove are vomit stains, because stomach acid and food products combined create an unpredictable combination that is hard to target with specific cleaning products.
Summary: Check for stains regularly. Clean dirt or smudges from a mattress. Fight urine stains. Remove blood stains. Lighten vomit stains.
