Dear Jo,
In marine mammal diet studies we use 70% ethanol for removing odour and potential problems with mould in fish bones and dry them afterwards. We used up to 24h with not effect of bones, but generally with 4h should be enough. We got mold sometimes in humid countries and we have to put the bones in ethanol for 5min, remove the mold with a brush and put the bones in ethanol again for hours.
Hope it helps
Gema

Subject: Removing mold from field collections?
Hello,
I arrived in the field to find some of the collections I'm working with
(mostly cavia and camelid bones) have developed a mold problem since being
excavated a year ago. Does anyone have any field-friendly recommendations
for removing it? We have no plans to do any chemical analyses, but I'd
still prefer to preserve the integrity of the bones. A quick search has
brought up recommendations of using 70% ethanol.
Thanks everyone!
Cheers,
Jo
