Need to buy an All Purpose Cleaner (APC) for cleaning vinyl cladding on my X3 as well as the inner wheel wells etc. Not really looking to spend a ton on money I feel it is more wisely spent on waxes, polishes etc. So what do you recommend as a general APC? I have seen some posts that are pro Simple Green. I would like to use something that is available locally (Lowes, HD, whatever). Dont worry, I spend plenty of money on other things at AG...just ask my wife. Thanks!
