Chemical Guys Foaming Citrus Fabric Clean is a 500ml concentrated carpet and upholstery shampoo built around a high-suds foaming action. Chemical Guys states the foam effortlessly lifts dirt for a quick, easy cleanup and leaves behind a refreshing citrus scent, with an oxygen-infused formula the maker also credits with lifting set-in stains. It is suitable for cloth seats, floor mats and carpets in cars, homes or offices, and the maker's own directions call for vacuuming first, then spraying, agitating with a brush and blotting dry with a microfibre towel. It suits interior details alongside carpet brushes, microfibre towels and a vacuum, rather than exterior wash products, and being concentrated it stretches further than a ready-to-use spray.
