What can be sprayed on glass to prevent water from sticking?

[AdalineLynn]

Anti-fog spray does not allow water to stick when applied to glass. Anti-fog spray: It is a low-molecular-weight dispersant containing hydrophilic groups, composed of molecules with a specific molecular weight. When applied to the surface of a transparent object, it forms a coating. The hydrophilic groups in the coating can adsorb water molecules from the air, wetting and spreading them on the surface of the transparent object to form a water film (instead of water droplets). This prevents light passing through the object from scattering and avoids fogging. Main components of anti-fog spray: They are primarily surfactants, such as xylitol esters, sorbitan monopalmitate, lauric acid, or glyceryl monostearate. It is an instant anti-fog formulation with a short duration of effectiveness and poor adhesion, typically lasting only a few days to a couple of weeks. The anti-fog effect disappears immediately after wiping or rinsing with water, so it cannot be used as a long-term anti-fog solution.
