I've used paper towels for a long time to wipe off dirt and excess oil from blued guns. I bought my first polished blued gun and after cleaning it, I noticed some fine scratches. Is it my imagination or do bounty paper towels have something in them that can scratch a finish? Or is this just standard wear for a high polish shooter. I knew holsters and such would leave scratches, just wondering if I should switch from good brand paper towels to something else.
