Gtechniq W4 Citrus Foam

Product Description

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 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.


It can be used at a dilution of up to 1:400 through a foam lance, or up to 1:25 through a pump sprayer.

Apllication Information

  • We recommend to use in conjunction with a jet wash and snow foam lance out of direct sunlight

  • For light dirt we recommend a 1:400 dilution, and 1:200 for heavier soiling

  • Allow the foam to dwell on the surface for 5 minutes and then rinse thoroughly

  • W4 can also be used with a pump sprayer at a dilution of 1:20

  • Do not allow the product to dry on the surface
