Gtechniq W4 Citrus Foam 5000ml - High Content Foamer, Easily Removes Dirt and Road Dirt - 100% Biodegradable, Non-Corrosive Formula - Maximum Gloss Retention Snowfoam

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
