I have a small collection of dice and one pair is from the Bingo Palace and appears to be decomposing. Should I isolate them form the other dice or just leave them alone.

Also have a pair of Stratosphere dice in a closed tube and when I open the tube there is a strong small of vinegar. Does that indicate trouble? Should I take them out of the tube? Do they need to be isolated from the other dice?

Thanks in advance for your help.
