Highly recommended to purchase the Glass Installation/Maintenance Kit, which contains all you need to maintain and care for your tiles. For normal care and maintenance of glass tile, wiping the surface with a damp sponge or cloth with water or a light vinegar solution is sufficient. If stronger cleaning is needed, a nonabrasive, neutral pH cleaner can be used. Glass tile may be damaged from impact with hard or heavy objects, which can lead to chipping or breakage causing sharp cutting edges that can lead to injuries. Always replace any damaged glass tiles immediately
