Gtechniq W4 Citrus Foam Shampoo and Degreaser for Cars, 169 fl oz

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.

This stuff works great and smells amazing too

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.

It’s a good product that works well

Not for winter muck. Light film in summer, ideal
