EverBright Mirror Film Anti-Soiling
Comparison to 4-mm Silvered Glass Mirrors
                                                                                         
All specimens cleaned three times.
Day 7: high pressure water spray
Day 28: water faucet, 20 seconds
Day 40: soap/water/cloth              
            

Average soiling rate cut in half!
