Gtechniq W4 Citrus Foam Soap

W4 Citrus Foam is a powerful yet gentle pre-wash snow foam designed to remove road grime and bug splatter without damaging coatings. Unlike traditional pre-wash snow foams that come loaded with caustic chemicals, W4 Citrus Foam is a pH-neutral formula that is tough on dirt but gentle on your vehicle's finish.

This 100% biodegradable formula combines an effective citrus degreaser with a foaming agent to make it tough on dirt and grime. W4 Citrus Foam can be used at a dilution of up to 10:1 through a foam lance and also through a pump sprayer.

For best results, use W4 Citrus Foam in a snow foam lance out of direct sunlight. Shake the bottle well before use, decant one inch (2.5cm) of W4 into a foam lance, and fill with warm water. Spray the foam onto the surface of the vehicle from bottom to top, and leave it to dwell on the surface for three to five minutes. Rinse thoroughly with clean water, and do not allow the product to dry on the surface of the car.

W4 Citrus Foam is an excellent addition to your detailing arsenal and can be used in conjunction with other Gtechniq products for optimal results.
