Yeh all acids are horrible, whenever I get my cars serviced I put a note saying not to use any wheel acid or truck wash on my car. Probably looks a bit sad I would go to that trouble but just don't trust most valeters who work for large delaerships, especially Renault ones, they are thick as planks!
AG SRP and CG Wheel Guard all the way for me...never have to do anything more than a quick wipe over using some soapy water and then a quick wipedown to get them to sparkle.
