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. Review: Uno dei migliori shampoo per auto mai provato. Ben lubrificato, ottimo potere pulente, delicato verso cere e protezioni. Poca schiuma ma la lubrificazione è comunque ben presente. Utilizzato in diluizione 1:1000.

The clear on "frozen" finishes meet the same standards, and G Wash is recommended for use with their coatings. **Q: Is this body shop safe ? Can I use this in fresh paint .. and are there any silicones in it** A: As far as I know it is since they are no abrasive in it however just to be sure you can contact a ceramic pro coating specialist, go on youtube or just google it. I use it because I had my car ceramic coated and it does not damage the coating. I would have to say it is safe to use after the paint is cured. **Q: How much do you add to a foam cannon? My chemical guys Cannon has a line on the side but it seems like a ton of product.** A: Check your settings. There are also inserts to reduce the amount of water going through the cannon to make soap use efficient if you have too powerful of a pressure washer ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by M***O on 28 January 2021* Uno dei migliori shampoo per auto mai provato.
