A pre-wash stage can help loosen road film before a contact wash. Gtechniq W4 Citrus Foam belongs in a complete wash process rather than being treated as a shortcut for every surface.

Check fit before you buy

Confirm the current dilution and equipment directions for hand sprayers or foam lances. Check compatibility with the paint, trim, protection products and environmental rules where the vehicle will be washed.

Plan the everyday workflow

Work on a cool vehicle out of direct sun, follow the dwell-time instructions and never allow the product to dry on the surface. Rinse thoroughly before beginning any contact wash.

Know the limits

Pre-wash foam does not make aggressive scrubbing safe and may not remove bonded contamination. Results depend on dilution, water, equipment, temperature and the condition of the vehicle.

Who should consider it?

Consider it when you want a repeatable pre-wash step before touching the paint. Buy only after confirming the instructions suit your equipment and wash location.
