Care of mirrors
Mirrors require special cleaning care. To clean mirrors, simply wipe over the surface with a few drops of methylated spirits on a damp cloth. Polish surface dry with a lint free cloth. Some proprietary glass cleaners, if used to excess, can cause damage to the silvering as can excessive amounts of water. Make certain when cleaning the face of the mirror that there is no contact with the silver backing, particularly at the edge of the glass and be careful to keep any moisture away from the paint backing of the mirror. Do everything possible to ensure that the cleaning cloths used are free of any abrasives.
