Wax & Grease remover or Prepsol will do fine, but basically straight after u have wiped that on u need to put a protectant on the rubber, as prepsol dries out the rubber making it easier to perish. I use CRC So Easy protectant as its different to Armorall, its anti-static, doesnt attract dust, and penetrates rubber nicely. Dont rub the protectant in....let it soak in by itself over a 15-20minute period, dont be scared to put plenty on, as like I said, Prepsol dries out ur rubber. But apart from that, you should be ok.
Nothing beats the sound of a V8
