Hi guys I’m new to detailing and was looking for some suggestions for an apc / interior cleaner. I have been using p&s express interior which works great, problem is, like most of their products they are quite expensive for little product. A 500ml bottle sets you back around £10 and got through about half of it just detailing the dash, pedals, centre console. I’ve seen suggestions on Bilt hamper surfex HD and autoglym interior does anyone know if these are decent?
