Gtechniq Auto W1 GWash Car Shampoo 1L — pH Neutral, Biodegradable Foam Cleaner with Pink Grapefruit Scent

Gtechniq Auto W1 GWash is a high-foaming, biodegradable car shampoo that gently lifts dirt and grime while protecting waxes and coatings.

Designed by Gtechniq using advanced surface-science expertise, this 1L Auto W1 GWash concentrates into a thick, lubricating foam that helps remove road film, tar and everyday contaminants without stripping protective layers. The formula is pH neutral, non-acidic and non-toxic, carrying a subtle pink grapefruit scent for a pleasant wash experience. It’s intended for routine maintenance by enthusiasts and detailers who want effective cleaning with minimal risk to paintwork or ceramic/wax protection.

How does this shampoo clean without scratching my paint?

Auto W1 GWash produces a rich, slippery foam that encapsulates and lifts abrasive particles away from the surface so they’re rinsed off rather than dragged across the paint. The lubricating action reduces mechanical abrasion during mitt or sponge use, and the chemistry weakens bonds between dirt and the finish for easier removal.

• Thick foam reduces contact between grit and paint
• Lubrication minimizes abrasion from mitt cleaning
• Surfactants break the bond between grime and paintwork
• Rinses cleanly to avoid residue build-up

Will Auto W1 remove sealants, wax or ceramic coatings?

This formula is pH neutral and non-aggressive, so it cleans without stripping sealants, wax layers or properly cured ceramic coatings when used as directed. It’s made to be safe for regular maintenance washes while leaving protective products intact, preserving gloss and hydrophobic performance.

• pH neutral, non-acidic formulation
• Gentle on polymer sealants and waxes
• Suitable for routine washing of coated vehicles
• Use recommended dilution to avoid over-concentration

How do I use the 1L concentrate for best results?

Measure a small dose of Auto W1 into a wash bucket or foamer according to the label, mix with water, then work from the roof down using a clean wash mitt. Rinse the mitt frequently in a separate rinse bucket and finish with a full rinse to reveal a streak-free shine.

• Typical dilution: follow label dosing for bucket or foam lance
• Wash top-to-bottom to avoid recontamination
• Use two-bucket or grit-guard method for safer washing
• Rinse thoroughly and dry with a microfiber towel for best gloss

• Subtle pink grapefruit fragrance improves user experience
