Glad I went and looked for this can for this post, looks like the bottom of it is corroding & expanding, I've had this stuff for couple of years now in the garage with the heat, guess I need to find a new container for this stuff if I want to keep it--
Be carefull This does not sound right Most solvents will have oxygen eating molecules as inpurities and the special plastic bottles will kind of shrink and twist inwards because the disapperance of oxygene is creating a vacuum If the vessal you have is expanding then a dangerous reaction has taken place and if you open that vessel it may explode in your face The liquid is destroyed anyway by this reaction so better try and dispose of the container in a safe way |

I agree with brother Sap, with only one small difference. Use small quantities of the solvents on the coin, but drink the much larger doses of vodka. I guarantee that when your finished, the coin will look better.
Believe it or not at one time I tried vodka but since it is 60% water it left nasty spots on the coin So I decided to drink what was left of the solvent  Vodka should only be used for drinking after reading the material safety data sheet (MSDS) It is toxic, it is flamable, only handle in well ventilated areas do not inhale the vapours , keep away from the eyes ; do not break bottles because this may be a reportable spill under SARA III ( super amendment reauthorisation act title III )  |

Ok, So I now know where to get Acetone. Thank you all. Now, is my understanding correct in it's OK to use on copper if not allowed to soak more than 30 min's ( to be x-tra safe ) at a time? This should aid in removal of: 1. PVC 2. Tape residue 3. Greenish Yuk, usually found on Indian cents ( forget the term, Old Timers disease ) 4. Various Dirt & Grease How about SILVER? Same results as copper or is it a different animal. I don't mean to HIJACK this Thread so: Any more input concerning "Nickel" I think this thread is containing a lot of GOOD info, valuable to so many people. Thanks for all the input. |

Anyone ever try or know if hydrogen peroxide is any good for cleaning off coins? Mainly just dirt or other junk.

Silver is totally non-reactive with acetone. You want to store your coins long-term in acetone? Go ahead - it won't hurt them. Your house will likely burn down sometime later because of acetone's incredible volatility, but it won't hurt the silver.  Irishraider, I've heard hydrogen peroxide can be an effective cleaner, but I have no personal experience with it. I don't know if it's any better or worse than equivalent compounds. |

I got mine at a hardware store a few yrs ago. Check there 1st. Read in this thread that Europe uses MEK, great solvent,but you can't get it here in the states anymore. Used extensively back in the 60's, but determined to be a carcinogen quote:

To the people who use acetone, "Where do you buy yours?"
Thanks.
I got 100% acetone at CVS just because it was close to the house. It will be in the nail section because 100% pure acetone is what the salons use to take fake nails off with and stuff like that. Its pretty cheap also, I got 16oz for I think about $3.00

Hi all, another comment on the use of acetone...Yes it does come in plastic jugs, but it will melt anything plastic with acrylic in it, therefore my warning about using platic bowls etc. If you know your container is not acrylic go ahead and use it..As to flammability, YES IT IS...be careful using it, don't smoke around the fumes(yes it smells strong) and store it like you would gasoline or alcohol, or any other flammable liquid. Hope this helps...

You might want to find out first if there is a health issue from ammonia coming into contact with PVC, especially the chloride part.

I can get a 1 gallon container of pure acetone in the hardware department of my local Wal-mart for less than $10. |

Did you rinse it after the dip? Is the nickel still looking ok? I know you didn't post too long ago but was just wondering if everything still looks good. Are you thinking of trying any copper? Edited by Irishraider

I only botted it dry with paper towel as the dealer suggested. Then I dipped an insignificant penny and that caused some discoloration. I just now mixed baking soda (I don't have any purified or that other kind of water sold at supermarkets, I can't remember what it's called, mineral water, can't remember. I will try that with baking soda as soon as I get it) with a small amout of water. I'm letting it soak for a few hours and then I'll blot it dry. I'll see what happens.  |
