</div>
<div class="moz-cite-prefix">if it is indeed mould (you would easily recognise this from the powdery spores), you can treat this with 70% EtOH. Otherwise, if it is "just" grease, the question would be if conservation treatment is needed.</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">Especially old whales have a lot of grease in their bones, and even if you would degrease the surface, the remaining grease would ooze out again. Which chemical decreasing, you would probably reduce the scientific value of the specimen,
because the chemical agents and decreasing procedure would affect the remaining proteins and lipids that might be useful for future research.</div>
