How to Get Vomit Out of a Mattress
Keeping your mattress clean provides you with a sanitary place to sleep. (Jupiterimages/ Images)

Vomit stains on your mattress create a protein stain that often includes colour dye from food or drinks along with its telltale smell. You can remove a vomit stain from your mattress but must treat each aspect of the stain. Similar to other types of upholstered furniture, mattresses need special cleaning methods that utilise the driest techniques possible. These methods remove the stain and odour without damaging your mattress with too much moisture.

  1. 1

    Remove vomit substance from your mattress by scooping it up with a spoon. Continue to remove as much vomit as possible. Dispose of the waste in a sealed trash bag to prevent your garbage can from emitting a foul odour.

  2. 2

    After removing the vomit substance, cover the site of the stain with meat tenderizer. The protein in the tenderizer breaks down the proteins in the vomit and absorbs odour-causing bacteria. Leave the meat tenderizer on the stain for 20 minutes. Brush the baking soda off and into the trash using a dry, natural-bristle scrub brush.

  3. 3

    Cover the site of the vomit stain with baking soda. Let the baking soda absorb moisture out of the mattress while deodorising the odour. After 30 minutes, brush the baking soda off and into the trash using a dry, natural-bristle scrub brush.

  4. 4

    Sponge the vomit stain with a cloth dampened with dry cleaning solvent to remove any colour stain. Dab the stain, starting at the outer area and working your way into the middle. Move to a clean part of the cloth as the colour stain transfers.

  5. 5

    Pour pet odour neutraliser on the site of the vomit stain to break down and absorb odour-causing bacteria in the mattress fibres. Allow the neutraliser to work on the mattress overnight.

  6. 6

    Vacuum your mattress to remove the pet odour neutraliser.

Tips and warnings

  • Substitute cornstarch or baby powder for the baking soda to absorb vomit liquid from your mattress.
  • Sponge your mattress with white vinegar to remove stains and odours.
  • Speed up the drying process, if your mattress is more than damp, by directing the air flow from a fan onto the mattress.
