Treat a beer spill on carpet as soon as possible to help prevent lingering odors and to reduce the chances of the liquid soaking through to the padding. Use a fan to help dry the carpeted area quickly afterwards when dealing with a large spill.
Removing Beer From the Carpet
Blot up as much of the beer as possible using folded paper towels. Continue blotting until no more liquid comes up.
Mix 1 tablespoon each of white vinegar and liquid dish soap into 2 cups of lukewarm water in a bowl or bucket. The measurements can be approximate rather than exact.
Dip an absorbent white cloth into the soapy solution, wringing out some of the liquid.
Wipe the area of the spill, working from the outside edges toward the center. Rinse the cloth frequently, dipping it back into the soapy water before applying it back onto the carpet.
Rinse the cloth once again and wring it out. Wipe the cleaned area from the outside edges toward the center to help remove any soap left behind.
Allow the carpet to air dry completely before stepping on it. If the cleaned area is large and the carpet quite wet, turn on a ceiling fan or use a portable fan, pointed toward the wet area, to hasten the drying process.
Sprinkle the cleaned area with baking soda if a beer odor remains after the carpet dries. Vacuum the carpet after 30 minutes or so to remove the powder. Repeat with another baking soda treatment, if necessary.
