To treat light carpet stains without synthetic chemicals, mix equal parts white vinegar and water in a spray bottle and apply directly on stain. Let the solution sit for several minutes then clean gently with brush or sponge using warm, soapy water. For a heavy-duty carpet cleaning mix, combine 1/4 cup salt, 1/4 cup borax, and 1/4 cup vinegar. Rub paste into carpet, leave for a few hours, then vacuum area.
