bilberry wheel cleaner (non acidic) this stuff is the greatest and im definitly not on my own when i say this, i recently changed my brakes and thought while i had the wheel off may as well clean the back of it, i looked at the mess back there bearing in mind my cv boot split and there was dirty grease and brake dust all over it within 20 mins a diluted bilberry cleaner had almost got every last bit. truly amazing, very cheap aswell. O then a nice coat of wheel sealent :rasp:
