Simply; The Best
As a dedicated amateur detailer I have read many reviews, and tried many products some good, others not so. With regards to shampoo's I have tried all of the usual suspects plus some of the more expensive offerings from companies like Gyeon but this product puts them all in the shade as it is simply amazing. When the 300ml bottle was delivered I was sceptical as it looked uninspiring, but after washing a a particularly grimy white Golf GTD and a Estoril Blue BMW 4 Series I am hooked. 5ml in a bucket of cold water produces a great result and appears to leave a silky hydrophobic coating on the paint surface, well done Bilt-Hamber.
