GTECHNIQ W4 Citrus Foam 1 liter

Gtechniq W4 Citrus Foam pH-neutral snow foam for powerful pre-wash

The Gtechniq W4 Citrus Foam is a powerful pH-neutral snow foam for safely pre-washing the car. The citrus formula produces a thick foam that adheres well to the surface and loosens street dirt, traffic film, and other pollution before you start the hand wash. Despite its strong cleaning power, W4 is non-corrosive and safe for ceramic coatings, wax, sealants, clear coat, and plastics. Ideal when you want to remove as much dirt as possible contactlessly during car washing.

Snow foam with citrus for dirt and traffic film

Gtechniq W4 combines a powerful citrus cleaner with a coating-safe, pH-neutral formula. The thick foam remains on the body for a longer time, allowing the cleaner time to loosen dirt and road grime. Then, you rinse away a large part of this pollution before touching the car with a wash mitt. This leaves less dirt during the contact wash that can be moved over the car paint.

Safe pre-wash for cars with ceramic coating

W4 Citrus Foam is especially suitable for cars that are equipped with a ceramic coating or other paint protection. The pH-neutral formula removes dirt without stripping the existing coating, wax, or sealant. Additionally, W4 is safe to use on various exterior parts, including car paint, plastics, rims, and glass. This allows you to treat almost the entire exterior during the pre-wash.

For foam cannon, foam gun, and foam generator

The Gtechniq W4 Citrus Foam can be used with a foam cannon, foam gun, or foam generator in combination with a pressure washer or suitable water supply. For the best result, Gtechniq recommends a dilution of 10 parts water to 1 part W4. Allow the foam to work for about 3 to 5 minutes and then thoroughly rinse the vehicle. For a complete wash, you can then proceed with a contact wash with Gtechniq GWash.

How do you use Gtechniq W4 Citrus Foam?

Shake the bottle well before use and ensure the vehicle is cool and not in direct sunlight. Dilute W4 in the foam cannon or foam gun at a ratio of about 10:1 with water. Distribute the foam evenly over the exterior and let it 3 to 5 minutes work. Do not let the snow foam dry. Then rinse thoroughly with clean water and a garden hose or pressure washer. For stubborn dirt in areas like wheel arches or the engine compartment, the product can be worked in with a wash mitt, microfiber cloth, or suitable detailing brush.
