This is my first post so everyone might thinking i'm taking the piss with this, but here goes! One of the thing that makes Meguiars Gold Class Shampoo so good for your paintwork is the fact it's pH neutral. Something else that is pH neutral is Johnsons 'No more tears' baby shampoo. Ive used that since I finished my last bottle of Gold Class and it gives the same, if not better results and is dirt cheap in comparison! Doesnt seem to leave as many marks while drying either!
