Most types of mold species grow well in warm, moist environments. Window condensation combined with dust and other organic materials in the surrounding areas creates the perfect environment.
One of the best ways to clean moldy windows is a multi-step process that gently removes the excess mold growth, kills any lingering spores and eliminates the excess moisture in the affected area.
Remove the Visible Surface MoldWith the window closed, spray a paper towel with your cleaning solution and place it over the moldy area. Avoid spraying the mold directly because the power of the spray could launch spores into the air.
Remove the Hidden MoldMake sure you clean the bottom of the windows, the inner surface of the window frames, and inside the window tracks. Don’t forget to clean the window screens and frames too.
Identify and Eliminate the Root CauseIf condensation and dirty window tracks are the cause, try deep cleaning the window tracks a couple of times a year.
