The titanite crystals tend to be encrusted with iron oxides, grunge and silica and don't always respond well to acid or "Iron Out" treatments. As well, they tend to be delicate and sometimes can break with aggressive scrubbing. One of the best ways to clean them gently is air abrasive using sodium bicarbonate. Here is Daniel cleaning a titanite specimen, thanks to the generous access to Ray McDougall's air abrasive unit.
