Auto W4 Snow Foam Car Shampoo and Degreaser For Cars, 100% Biodegradable Non-Caustic Pre-Wash Snow Foam Car Wash, 5L

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

Good product lasts ages on the car. High amount of foam using a autobrite foam gun ,very good at removing insect and grime

It’s a good product that works well

Perfect snow foam to use maybe twice a year, during and after the winter months as it is extremely effective in removing grime and salt deposits which will accrue on paintwork at that time. Not to say it can't be used at any time of the year, but I prefer to keep it for when it's needed most. Great value by buying this larger amount.

WOW this is very foaming and a nice smell great product 👌

I have been detailing now for many years and i have to say that this product is one of the worst i have used. The main problem is the viscosity especially on colder days, to get this product to work in my AVA Premium Snow Foam Cannon i have to bring the product inside a few hours before use or the instructed ratio will not mix properly with the water and i will get a watery consistency on the vehicle. Second to this it removes next to no top dirt, so much so that i have used products half the price of this and got way better results. This is definitely something that car detailers need to AVOID at all costs

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.

Outstanding product

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
