If I may add something to this, My wife and I discovered last summer that if you make a paste out of baking soda and white vinegar [ not to much vin] though it will bubble all over the place , this with the aluminum foil really does work great. then we also used one of those magic erasers for the fine rust then cleaned all with windex my rims and front fork covers are terrible but it seemed to work so far but we never finished yet. Just thought I would let ya'll know .
