Gtechniq W4 Citrus Foam is a pH neutral pre-wash snow foam that removes hard to shift grime, without damaging sealants, coatings or waxes.
W4 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.
- 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
- Do not allow the product to dry on the surface
