Pure Alcohol is best. I use water free rubbing alcohol from the drug store. Be careful and don't breath too much in or get too much on your skin. First dry brush as much as possible.
Some low W0 or W1 chondrite slices can be further cleaned with sulphuric acid. Now you need to be really careful. I use navel jelly in order to remove rust stains. I have left stuff in for an hour with great results and Zag especially cleans well. With these acids you must know what you are doing so if you are not sure ask for help from someone who knows how to handle these chemicals. Once I forgot a specimen for a few days. Fusion crust completely eaten away. ;>) Cheers, tett ----- Original Message ----- From: "Gary K.
