Just curious here. I just stepped out of my study for a bit, when I heard a distant sneeze emanating from my 4 year old. I returned to find tiny water stains  on about 15 BU 2010 coins. The little house-ape's epizootic droplets have dried to little white stains. I was thinking about taking a microfiber cloth to them. Will this rub up the highpoints? Any suggestions?

I wouldn't rub them with a cloth but a quick dip in acetone should take the saliva away.

Fwiw I have not seen microfiber damage coins after testing at 50x magnification.

Thanks guys. I tested one on 12x didn't see any scratches but it didn't remove the stains either.

Should go with acetone. Can find it at Wal-mart in the paint department or any paint store.

Going to try to get some acetone today, Numisnut. That won't harm the finish right?

It won't damage the metal or the finish at all but you should do it quickly as saliva is very acidic.

The microfiber itself is not the problem, clean microfiber is too soft to cause abrasions. The problem is the dust particles and other grit on the surface of the coin and in the cloth fibers- that is what will create hairlines. Dry mechanical contact on a coin will almost always leave hairlines, wet methods are superior in every case. Acetone is harmless to the coin but it is a flammable solvent so you should take proper precautions when handling, it is safe for use when handled properly.

Try Lowe's. They have acetone. Hey guys wouldn't distilled water loosen that stuff up also?

I don't think distilled water would move the stain.

Micro fibre cloths are used in detailing new cars for final polish. Car paint is a lot softer than a metal surface.
Beware! The cloth has to be new; they have a great affinity for dust, which could ruin a proof coin.

The main thing here is to use Distilled Water, not tap, well, spring, etc waters. Allow those coins to soak for a day or two in Distilled Water prior to anything else. If this doesn't work, then try the Acetone. HOWEVER, if your not familiar with the usage and cautions of Acetone, first do a Search on this forum for that topic. There is that Search Tab at the top of the page. Any rubbing with anything could cause a problem so don't take chances.
