What to Use to Wipe Glass to Prevent Fogging?

[LaJosephine]

You can use dish soap or soapy water to wipe the glass to prevent fogging, because soapy water and dish soap contain surfactants that effectively prevent water vapor from condensing on the surface, thus serving as an anti-fogging measure. Mix dish soap and water in a ratio of approximately 1:10, then use a soft cloth to apply the prepared solution to the inside of the front and rear glass. Wiping it first and letting it dry will enhance the anti-fogging effect. The principle is as follows: 1. The active molecules in dish soap can be divided into two parts: one end is a charged, polar hydrophilic group, and the other end is a non-polar hydrophobic group. 2. The active molecules can disrupt the surface tension of water. When soap molecules enter the water, the polar hydrophilic part breaks the attraction between water molecules, reducing the surface tension of water and allowing water molecules to spread evenly on the treated glass surface, forming a water film that adheres to the glass. 3. The more rainwater hits the glass, the larger the water film becomes, maintaining the glass's high clarity at all times.
