G Wash

I’ve been using Gtechniq W1 Auto Wash for several weeks now, and it’s quickly become one of my go-to car shampoos. As someone who takes pride in maintaining their vehicle properly, I look for products that offer great cleaning power without compromising paint protection—and W1 delivers on all fronts.This shampoo produces low suds, which may surprise those used to thick foaming shampoos, but don’t be fooled—its cleaning performance is excellent. It effortlessly lifts dirt and road grime without needing excessive product, meaning a little goes a long way. It rinses cleanly with no residue, leaving behind a spotless, streak-free finish that really enhances the appearance of the paint.One of the standout features is that it’s completely wax and sealant-safe, making it perfect for maintaining ceramic coatings or synthetic sealants without breaking them down. It’s also highly concentrated, so you only need a small amount per bucket, adding to the overall value.If I had to mention a minor point, it would be that because it’s a low-suds formula, it doesn’t offer the “foamy wash” experience some enthusiasts enjoy—but this is purely personal preference and doesn’t impact its cleaning power at all.Overall, Gtechniq W1 Auto Wash is a professional-grade shampoo that does exactly what it claims. It’s a high-performing, no-nonsense product that works brilliantly for regular maintenance washes. I’ll definitely be buying it again and would recommend it to anyone serious about proper car care.

Excellent car shampoo without any nasty chemicals or waxes. A little goes a long way.

Very good stuff especially since I'm living in London area leaving water spots everywhere after washing with cheap shampoo (Halfords own brand, etc) you don't need much mix with water in a bucket & the result was amazing 👍

Good quality shampoo that goes on easy and leaves a nice clear finish. It doesn’t foam up as much as I expected but that’s not always a bad thing I guess.Apply with a bucket/wash mitt, easy on and easy rinse with pressure washer/hose. It does a good job.

Great produce

A little goers a long, long way...Added the recommended 4 capfuls to my ubiquitous Orange Bucket & this Shampoo cleaned our SUV with 1/4 bucket left over.Super Foamy and super Slippery too. Makes Car Cleaning easy, effortless and leaves the car looking great with no streaks & all dirt removed.Highly recommended for those wanting a clean vehicle with minimal effort with a quality product. One of the best I have uses &, although it is not the cheapest, the bottle is going to last a very long time...

You have to use very little o fit to do a FANTASTIC job!!

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.

I’m no car wash expert, but I could tell that using this on my car delivered a really safe and solid clean. It foamed really well, didn’t need a lot either! I picked this specifically for my car that has been treated with professionally applied ceramic coating to not damage the coating.

Best Car Wash I’ve ever used it removes dirt and sand really quick and helps maintain my car and looks like brand new. I don’t remember. the product definitely lasted with me for more than 40 washes.

Encantado con cómo quita la suciedad! Funcionó muy bien con el aplicador de shampoo que hace que salga en forma de espuma, e hizo que se despegará muy fácil la suciedad y los insectos pegados a la pintura

Great car wash foam. Perfect for cars that have ceramic a coating.
