How do you get glue off of marble?
Marble is composed mostly of calcite (a crystalline form of calcium carbonate) so avoid any acidic material as it will eat into the surface. Some marbles (European) are softer than American marbles so be cautious about using abrasives which mat remove any polished surface. Glue may seep into the porous surface of the stone and may make removal difficult. There are special cleaners available but these should be discussed with a local marble cleaning company. Once the stone is clean consider covering the surface with a marble sealing compound.
