Does not do what it says.After mixing to ratio stated, applying and leaving to dry on two vehicles one for an hour and one over night. I hosed off as per instructions.It then says to chamois or just leave to dry for a sparkling finish.Well, the vehicles both need a sponge wash, still dirty.Dissapointed to say the least.

Have bee using CT18 super wash for years. It’s my go to product for cleaning. It’s pH neutral so will not damage surfaces.
Good value automotive wash. No insane frills, just good soap. What more can be said about car wash liquid? It's all that's asked for at a reasonable price
Good chemical to clean off your sand and mud from 4wding. Pair this with a pressure cleaner and you have the same as a self serve car wash!
I have been using this product for 5 years.Do it waste your money on other Better marketed products eg McGuire’sThe products worlds well in a snow foam gunThe product is not to harsh but can remove bugs and tar easilyAlways leaves my vehicles looking like newYou can also use it around the house on tiles or washing bricks, pavers etcJust buy this product and you will not regret it
Got tired of buying small bottles of soap, decided to buy the first big bottle I seen.This stuff is great! I've never noticed a difference using other soaps, this is the first time ive been impressed by soap... I dont think I'll ever use anything else again
Easy to use, non-streaking when dried on the car. You do really need to agitate it (with a sponge) to totally get all of the road grime off. But overall very happy with the result!
I’ve been using the CT18 now for over 25 years originally using on my trucks, now at home on my 2 4x4 and our Caravan, it cleans about 80% of the dirt of o coarse you still need to either use a bush or sponge to get 100% clean
