( 3 ) Remove dust or stains, using an air blower or a soft cloth moistened in cleaning solvent. However, do not perform the above cleaning using a soft cloth with cleaning solvent in the marking portion. In this case, use only the following type of cleaning solvent used for wiping off : Ethyl alcohol, Methyl alcohol, Isopropyl alcohol When the cleaning solvents except for specified materials are used, please consult us.
