I have Tony,

Did some spot tests on various materials. Oxalic acid , as an acid, will attack soft metals like aluminum as well as brass, and discolor it if left on or two strong a solution is used. But then, so will alkali substances like the ammonium chlorides in your spray bubbles. But the method mentioned regarding brushing with a clear water source nearby will work with any of these as long as you watch it and don't leave it on for too long. I've found oxalic acid is much more effective for neutralizing rust on steel and chromed parts that aren't too far gone, but you could try it on your rims if the bubbles don't cut it. Neutralize the acid with bicarb of soda when done. Rinse well.
