Get out the color cover by brushing it with an solution of 1 container white refined vinegar for each gallon of water. (Continuously test on a far away some piece of the floor covering heretofore).
Some floor covering stains could be uprooted with a glue of 2 tablespoons white refined vinegar and 1/4 glass salt or preparing pop. Rub into the floor covering stain and let dry. Vacuum up the deposit the one day from now.
