After having my S3 for almost half a year and surviving a harsh winter (not helped by my car park having four trees in it that sprinkle **** all over it everyday); she's starting to not look at majestic as usual - I try and get around to washing once a week:
Quick spray with the jet wash
Soapy warm water with some turtle wax in to and a sponge to get rid of the grime
Then dried with a leather
Is there any extra steps/products etc. I should be using to get a really good, long lasting clean and shine?
