Step #1: Use a spoon to scoop up as much as you can then Blot with a white paper towel to remove as much debris as you can.
Step #2: Neutralize the stain with a ammonia solution of (1) tablespoon of clear household ammonia to 1/2 cup of water). Saturate spot with the ammonia solution using a spray bottle “Do not over wet the fiber, Do not get the carpet backing wet”. Allow to stand for a moment then blot dry with a paper towel.
Step #3: Apply a small quantity of cleaner to the stain. (To make the cleaner solution – mix 1/4 teaspoon of a hand dish washing detergent such as Dawn® or Joy® with a large cup of water) Use a blotting motion to work the cleaner into the affected area. If the stain is being removed continue applying detergent and blotting with a white paper towel until the stain is gone.
Step #4: Rinse with tap water using a spray bottle, blot dry to remove excess moisture.
Step #5: Spray lightly with water, do not blot this time; apply pad of paper towels and brick and allow to dry
Step #6: The next day, if the stain is still there: You are going to use a very common household product of 3% Hydrogen Peroxide. Moisten the stained area with the Hydrogen Peroxide (using a spray bottle) and let it stand for one hour. Repeat this one hour later if necessary. If any staining remains – Agitate, rough up the area with a paper towel, spray once again and then put a folded paper towel on the stain and a weight like a brick on top of the paper towel and let stand until the next day.
NOTE: Light will cause peroxide to change back to water so no rinsing is necessary.
