Next Level

I've used GTechniq products for a while now as all my cars have GTechniq ceramic coatings on them so I was quite used to the first version of GWash and it's capabilities. I was really impressed by just how much of an improvement v2 is over v1. The improvement in lubricity is stark. It really feels like it's gliding over paintwork yet pulls dirt off the car with genuine ease. It's still easy to rinse off and leaves an absolutely fantastic finish. I'd go as far to say that GWash v2 is the best car shampoo I've tried to date.

you can't go without this!

If you got any of the Gtechniq coatings you can't go without this! I tried it on a polished and cleaned hood this wash really does add the formula of C1 series, not much but it does enhance existing coatings! nice fragrance added to it bubblegum/cherry Makes working with it a pleasure! good dilution doesn't need much to be effective but I can recommend a Prewash before using this ! 4 out of 5. not suitable for high dirt. more as finishing Wash to enhance the existing coatings! good value to!

Fantastic for shifting dirt

Excellent cleaning power and easy to use in conjunction with a pre-wash. You don't need much product given how well it shifts dirt with just a couple of capfuls. Lots of suds produced and I live in a hard water area. Smells great and rinses off well but do rinse thoroughly. Note: it doesn't have any 'water dispersal' properties that the Koch Chemie shampoo does for instance. Hence it takes that little bit longer to dry the car.

One of the best

Great lubrication, cleaning power and easy rinsing. Smells of cherry which tops off what is already a great shampoo.
