Cleaning Silver Maples

Thanks Guys. So a 1 minute dip in pure acetone, and then air dry? Or remove from acetone and straight to a rinse with water and pat them dry with a microfibre?

The thing is, they still look shiny like brand new. I don't visually see any fingerprints or oils on them right now. But I want to prevent any smudges/tarnishing from appearing in the future.

Dip in acetone for a minute.
Rinse in clean acetone.
Air dry.

Acetone is unlikely to help, but worth a try I guess.



to the CCF!

All 2018 Maple Leaf silver bullion coins and newer should no longer experience milk spot issues https://www.coinworld.com/news/prec...pot-fix.html

I'll play around with it more eventually, but some positive results have been shown from using EZEST, the key is diluting to 1/2 EZ Est 1/2 Distilled water or even 1/4 strength EZest. Another key is to be quick with the dipping, perhaps 2-3 seconds only then rise with pure distilled water. Anything more than that will start to ruin the surface which is where most likely gave up, so perhaps a little practice on some bullion that has no premium value would be a good start and then can move on to those pieces with value. Milk spots on the other hand apparently wont work by that method once they have settled in. It usually works more on the Haze/Cloudiness such as in silver proof quarters for example.

I would say you are being overly worried about it as the coins from what you say are not low mintage collectible versions where its important to keep in best condition possible and can be graded, but are the standard bullion sold for their silver value.

Milk Spots are different than oil which may differently react with the metal surface over time, leading to corrosion and discoloration. Before 2018 the canadian maple leafs did sometimes have milk spot problems but they seem to have fixed that problem.

Over time, oil can penetrate the coin's porous surface, making it increasingly difficult to remove. Oil can attract dirt and dust particles, further compromising the coin's appearance and overall value but again thats more in general for collectible coins such as when you buy a limited edition with low mintage to keep it in top condition. For those bullion coins you can just do the EZEST or acetone if you feel you really just want to try to remove the oil to keep them looking good but its probably not needed since they don't appear to be in any worse visual shape per your post.

atc250r An acetone bath would not hurt, it may ease your concerns.

Assuming they are "just bullion" maples then do a quick dip in E-z-Est (less than 1 second), rinse thoroughly, pat dry then repack in tubes.

Well done, and sounds like a good plan.
