Went out to the garage last night for a little "I've got to get out of the house" therapy and tried to get the winter grunge off my wheels. Was using "Simple Green" brush and hot water. Needless to say there is still some grunge on there. What do you use to get that crap off during the winter? Looking for more of a spay on type of stuff that wont take the finish off aluminum wheels that I can use in the garage (it was -6 last night so hooking up the power sprayer is out of the question).
