Combine one teaspoon of hand dishwashing detergent with two cups of cold water.
If the blood stain is already dry, scrub with a steel brush to loosen the stain from the fibers of the carpet.
Dip a clean cloth in the mixture and blot directly on the blood stain until it is removed. Blot repeatedly in an up-and-down motion, working your way from the outside of the stain to the center to prevent spreading.
IF THE ABOVE METHOD DOESN’T WORK, TRY:
Combine one-half cup of warm water with one tablespoon of ammonia.
Apply solution directly onto the blood stain.
Blot with a clean cloth until nearly dry.
Press with a sponge dipped in cold water to soak up the chemicals.
Harden the gum by filling a plastic bag with ice and placing it on the stain for a few minutes.
Use a dull knife or other scraping tool to scrape the gum from the fibers of the carpet.
If the gum is being stubborn and refuses to pull free from the carpet, spray a generous amount of WD40 directly onto the stain.
Scrub with a stiff brush or nail brush in only one direction. If you’re scrubbing from right to left, resist the urge to switch the direction or pattern. Your goal is to pull the gum free from the carpet. Scrubbing both ways will only rub the gum deeper into the carpet.
Repeat until the gum is cleared from the fibers.
Spray the area with carpet cleaner or degreaser and gently scrub with a sponge dipped in warm water.
