Hmmm. I use hoppes. No problems...yet. Is the "damage" just cosmetic? I clean my guns after every shoot, and I clean my carry every couple of weeks to keep it lint free, etc.

While I would like to keep my carry piece pristine, it is an every day carry. If it is just cosmetic, I wouldn't worry about it (I don't know if the damage is limited to cosmetics - I assume it is, as it's just the finish).
