Please wipe the surface of the glass cleanly before use, spray the spray on the inner surface of the glass (note that the anti-fogging agent can be sprayed thinly, it is not suitable for spraying too thick), then gently dry with a towel. Wipe evenly. Just wipe gently and evenly without any traces. Too much force will wipe off the active ingredients of the anti-fogging agent on the glass surface. Because the towel will absorb the anti-fog liquid and leave only a few active ingredients on the glass, affecting the effect. 2.Spray the anti-fogging agent directly onto the paper towel, spray more points, then directly wipe the lens and apply it evenly. Wait for 10 minutes to dry naturally and try again. 3 About anti-fog aging: Normal about 10 days oh Depending on the use environment Temperature below 0 degrees will affect the anti-fog effect Active: car Windshield;Bathroom mirror;Lcd;Mobile Phone Screen;Glasses;Helmet
