Sadly a couple of my bullion bars have black spots on them. :-( I started putting desicant in every box i have, though is there anything i can do get rid of them, or will they just eventually grow like mold and surround the entire bar with black???
carbon spots from improper storage most likely you need to put them somewhere else or yes it will get worse.
How big are the spots? If they are small, its quite possible someone just talked over them (or sneezed) and they got specks of saliva on them.
Not a bad idea to wear your mask when handling coins, especially proofs. Saliva droplets will come back to haunt you.
E zest coin dip works on my bullion if I want them pretty. Wear gloves Dip, Rinse in hot water, pat dry with a Terry towel.
Not to sidetrack, but some say to rinse Ezest with cold water, some say warm, some like it hot. So...does water temperature make a difference?
Probably not but I feel hot/warm water drys faster. Less water spotting is my guess. I then put the bars in a holder and ziploc bag to help keep them from oxidizing. Less air available less oxidation. Think like airtight storage containers.
They are bars, by definition bullion. If it bothers you any silver coin cleaner will remove them, and simply rinse with distilled water. I literally have no clue if my silver bars have any spots on them, have never cared enough to look. I did like having them in my pocket in larger cities. I usually bought a couple of 10 ouncers when I visited Chicago or NYC. Would carry them in my pocket in case I needed them, and when I got home tossed them in the safe. Great excuse to buy bullion.
