To make a vinegar anti-fog solution, combine 2 tablespoons of white distilled vinegar with 1 quart of warm water. Pour the solution into a spray bottle, or wipe a soaked cloth directly on surfaces. Allow the surface to dry, and reapply the solution every two weeks.
- Create the anti-fog solution
Combine 2 tablespoons of white distilled vinegar into 1 quart of warm water. Stir the ingredients together for several seconds.
- Prepare the solution for application
Pour the solution into a spray bottle to apply on non-mirrored surfaces. Alternatively, keep the solution in its mixing bowl for use on mirrored surfaces.
- Apply the mixture
Spray a liberal amount of the solution on non-mirrored surfaces, such as windows or on bathroom appliances. Do not wipe the mixture away, but allow it to air dry. Dip a clean cloth into the water and vinegar solution. Wipe down mirrored surfaces, such as bathroom mirrors or car mirrors. Generously apply the solution, and allow it to fully dry. Do not wipe the surface clean with a cloth, as this removes the anti-fog properties from the surface.
- Repeat the process every two weeks
To prevent fog development, reapply the vinegar and water solution every two weeks. Heavy-use bathrooms or areas that experience high humidity may require more frequent applications.
