Why use W4 Citrus Foam
Unlike traditional pre-wash snow foams that come loaded with caustic chemicals, W4 Citrus Foam is a pH neutral formula that removes hard to shift grime without damaging coatings.
It combines an effective citrus degreaser, with a foaming agent, making it tough on road grime and bug splatter. It can be used at a dilution of up to 10:1 through a foam lance. And also through a pump sprayer.
