GWash Shampoo breaks the bond between the dirt film and your vehicle’s paintwork and lubricates dirt particles, while at the same time minimising surface abrasion for a clinically clean finish.High Quality Foam ContentWhen you wash your car with GWash, you’ll find that it produces a high foam suds content. This high content promotes the breakdown of the bond between the dirt film and your vehicle’s paintwork. It makes it much easier to clean the dirt and grime from everyday use from your car. Works with Any Gtechniq CoatingWhen you use W1 GWash, you can rest assured that it will not negatively impact your Gtechniq coating or sealant that you have already applied, as GWash has been specifically formulated with a 100% biodegradable, pH neutral formula that works in harmony with Gtechniq’s range of coatings. Retains GlossIf you have applied T1 Tyre and Trim, T2 Tyre Dressing, Quick Detailer, Panel Wipe or a number of gloss boosting products by Gtechniq (all available on desertcart), then usng GWash Shampoo will ensure maximum gloss retention through the excellent lubrication of dirt particles, which in turn minimises the surface abrasion, and promotes gloss retention.Easy To UseShake product well before using this product, and do not apply in direct sunlight. Add two caps (20ml) for light dirt, or four caps (40ml) for heavy dirt, into an empty bucket, and fill bucket with water (for best results use warm water). Start washing from the upper surfaces of your car and work downwards, and when finished, rinse thoroughly with clean water to remove all surfactants.Store in a cool, dry place – Use within 12 months of opening.
