Hi,
I've got a potential problem on my immediate horizon. We are hosting a number of marble sculptures and I noticed one has a dozen small loose pieces and they used packing tape to strap them in place. The object and the seeds are marble. They have been stored in a storage unit or garbage for a number of years. I'm preparing myself to clean them if necessary.
Will mineral spirits or rubbing alcohol affect the sculpture? It was suggested on another webpage for household sculptures.
