Outstanding product

Their line of car wash items are great. I use it on both my cars. Products are good quality. Foams well and removes media effectively. Their shipping and packaging is on point. 25 G80 M3 MT 22 Etron sportback 95% of of my car wash supplies come from Gtecniq. Definitely recommend.

Use with a pressure washer and foam cannon for car washes on a Tesla.

The major complaint that I have is It’s almost impossible to transfer the soap over to my foam cannon bottle without spilling soap. Basically I’m waiting soap because if the poor packaging design. Other than this, the product works as expected.

I bought this because gtechniq is a reputable brand. Not sure if it’s me using it wrong but I filled my foam cannon with about half soap and it still doesn’t foam. Hence the name “citrus foam” Turns into a thin layer of soapy water. Might as well have just used dish dawn soap. I don’t usually write reviews but I’m beyond disappointed especially for $70 a gallon. Going back to gyeon soap

I used this as a pre wash in my Karcher pressure washer dispenser. It gives lots of foam which lasts well, and is simply washed off after 5 mins. After a normal wash the paintwork certainly seems to be cleaner and shinier than when washed without using this first. Would definitely recommend.

Dose what it says on the bottle, pressy for my son , its a big bottle full so good value for money, he's well pleased with it

Great shampoo

Difficile de faire une belle mousse avec. Je ne sais pas trop quel matériel utiliser avec

Defo needs foam cannon, pump sprayer no good
