One of the most common problems car owners have—tinted windows or not, are hardened water spots during winter. Hard water spots are caused by minerals like calcium and magnesium content in water. When a surface gets wet—whether it is covered with tint film or not, the water evaporates the moment it was exposed to heat. However, the mineral deposits are left behind. The stuff that’s left behind is super-concentrated, so it’s hard to see through and even harder to remove
Meanwhile, water spots are a mixture of water and soap, acid rain, or some other type of contaminant. When the water dries, all that’s left on your windshield is the chemical.
Sprinklers, car washes, and rain showers, and even snow can all cause hard water spots to form on glass. Chemically speaking, these deposits are alkali, requiring an acid to remove them away. This may sound easy for car owners, especially because of the numerous choices of acid based cleaners there is in the market today. However, cleaning tinted car windows requires a little bit more of research.
The main difference between cleaning tinted windows from cleaning non-tinted windows is the things you should use, and the things you should avoid. Knowing what products are bad for your tinting will help prevent you from accidentally doing damage to it or reducing its life. Cleaning newly-tinted windows is a simple process as long as you know what materials and cleaners to avoid. You have to be extra careful on cleaning your tinted windows if you want your tint to last a long time, still looking good as new.
Tinted windows are more delicate, given that the film installed are thin and can be easily removed if you’re not careful. You’ll need to use gentler cleaning products on your tinting to preserve it, and under no circumstances should you use a cleaner with ammonia in it. Ammonia based products can reduce the darkness of your tint or cause its material to become dry, brittle, or otherwise imperfect.
