Looking to buy this set of preserved owl butterflies but I've noticed that two of them look like they have a few spots of mold on them. Anyone have any tips on cleaning them off or making sure the mold is dead without damaging the specimens? I can easily get them out of the shadowbox they're in for cleaning, but I don't want to ruin them and the shadowbox would be too big to fit in a bag to put in my freezer. Any suggestions would be appreciated!
