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 sealants, coatings or waxes.
It combines an effective citrus degreaser with a strong foaming agent making it tough on road grime and bug spatter but kind to waxes and coatings.
