A good carpet spot remover is Resolve Triple Action Spot Cleaner Remover, according to Real Simple. This remover is easy to find in supermarkets, cleans up even dark stains and helps deodorize.
Other stain removers may also work well on carpeting, plus upholstery, according to Good Housekeeping. Hoover Platinum Collection Instant is an aerosol spray that removed food stains well in one use. Bissell OxyPro works well on food stains, particularly wine stains, both recent and dried after 24 hours. For something more inexpensive that may be easier to find, customers can turn to Weiman Carpet Cleaner. This spray works well on food stains, but does require extra work to remove darker, dried stains.
