Using a brass brush on chrome irons

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?

It could damage other finishes, and it could chip off a really bad plating job if it was already cracked or got damaged from bending, etc. But the dirt is more damaging than the brush imo. Nothing to worry much about.

that is accurate, i never use a brass brush for anything. use a nylon brush. it does the same thing, and it won't scratch the surface. overtime the brass brush will eat away at the finish of your pretty irons.

I usually use the nylon bristles but sometimes that isn't good enough. Have used the brass bristles occasionally and no problems to report. The nylon just doesn't clean the grooves all the time but he brass does. IMO of course.
