Gtechniq W4 Citrus Foam 5000ml - High Content Foaming Agent, Removes Dirt and Road Grime Effortlessly - 100% Biodegradable Ingredients, Non-Caustic Formula - Maximum Gloss Retention Snow Foam

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.

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

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.
