I do not have chrome plated clubs and i use a brass brush to clean my irons. Works fine for me and i have never noticed any problem. A month ago i caddied for a lady who had KZG chrome finished irons and she told me 'do not use the brass brush on the irons, will rub off the chrome'. Is her thinking accurate? Will the brush damage the chrome finish? Will a brass brush damage an ordinary iron face?

Typical Brinell Hardness Numbers for Metals

Hard chrome plating is around 700 per one reference I looked up. So brass is a lot softer and should not scratch. However, the Mizuno site does say not the use brass. I just use nylon because I hate the brass bristles jabbing into my fingers if I grab it the wrong way.
