"Isopropyl or Isopropanol (IPA) is typically what's used for, now read slowly, """degreasing and/or drying or dehydrating"""." True. Here's a tip given to me by Mike Marotta's mom. When using a glass/mirror cleaner like Windex (for all you Greek Wedding fans out there...) cut the cleaner by half by adding an equal amount of IPA to it. Spray. Wipe. It does a great job. Don't do this to your coins, though. ;-) Anka Z Co-president of the once thriving, but now defunct, Tommy John Fan Club. Go, Lake County Captains! |

"Jim" wrote in message ... "Dale Hallmark" dalehall.Notthis adds..... I have cleaned a proof coin with no scratches on it with acetone and a 1/2 inch $35 sable hair artist brush and seen scratches in the fields afterwards. I have no real explanation. No gold star for you Dale, you weren't reading. The reason for that is this simple. You "didn't" clean the coin. You removed whatever the acetone could remove, but that which was not organic solvent soluble, like simple everyday environmental surface gooks, crud and developing tarnish, were still on the surface of the coin. When the sable brush was hauled out, the brush bristles simply smooshed those cruds hither and yon. It is the plow troughs in that crud that you are seeing. Had you soaked the coin in any soap or detergent first, you would have removed those organisms that alcohol and acetone "can't" and won't ever remove, despite what 3,908 posters to RCC yesterday, today and tomorrow and the anecdotes they rode in on, will say. HTH......I'm here between beers, to serve annoy and posture for all Google posterity and maybe a caustic mention or 5 in someones demented little web pages and no mention whatsoever in the next awkward Periodic Post re cleaning coins. makes sense Dale |

"Pure" alcohol is "anhydrous", meaning no water content, unlike isopropyl,
which is usually 70% alcohol and 30% water. "Doggo" wrote in message ...
