DIY Stain Remover
Scoop up any solids with a dull-edged knife, and blot liquids with a white cloth, working from the outside in to avoid spreading.
Dab the stain with cool water, or cool water and nontoxic dishwashing liquid.
Sprinkle an oily stain with cornstarch and scrape up after 10 to 15 minutes, repeat as necessary, dab with water solution, and rinse.
White vinegar, lemon juice, and hydrogen peroxide are all mild bleaches (test a discreet spot first) that can take care of many spots. Presoaking an item in nontoxic laundry detergent or oxygen bleach is another effective treatment.
