Hi Allison-
I received some more information concerning the care of the oceanic objects in your collection from one of our C2C Care experts (along with a request for some info if possible). See below and thanks again for your patience.
It is relatively common for collection managers, curators, or other staff to do dusting in smaller museums that have no conservators on site, but if possible, get a contract conservator in to consult. Since dust can be harmful, and conservators can be expensive and hard to come by, dusting is usually ok.
Anything more invasive than minor light dusting should definitely done by a conservator, or at least under the supervision of a conservator. The task might be quite do-able by an untrained person, but the conservator is needed so you know where things can go wrong.
Better yet is to avoid dust happening (storage in boxes or closed cabinets, display in closed display cases, etc.). Looking back at the question, Allison appears to be talking about items in storage. Ideally museum objects in storage should not need dusting because they are packed for protection in boxes. This is the main approach I would take here - find ways to prevent dust build up on collection objects, rather than dusting to remove dust after it has happened, through the use of boxes, dust covers, cabinets, good quality HVAC air conditioning, and a good house cleaning strategy of keeping non-artefact surfaces clean and dust free so there is no dust reservoir.
I need more information to get some idea of the source of the smell. e.g. How long the rocks have been in storage, what environmental conditions they've been stored in, and were there past practices of spraying things with pesticides? Improving the environment with better humidity control may help if the environmental conditions have been bad in the past. High toxicity from the smells is unlikely, but if there is mould, or past pesticide use, then Allison would want to wear a mask when dusting. Gloves should be worn when handling objects regardless."
