Tips for Removing Mildew From Your Vinyl Windows

Isaiah Brewer

One of the great benefits of vinyl windows is the ease with which they can be cleaned. Washing your windows and removing mildew is a relatively simple procedure as long as you have the correct tools.

Outdoor Mildew Removal

To remove mildew from the exterior of your vinyl windows, use a solution comprised of equal parts oxygen bleach and water. Oxygen bleach is better than chlorine bleach because it won't damage plants beneath the windows. However, check with your window's warranty before using oxygen bleach. If oxygen bleach is prohibited on the warranty, use vinegar without water to wash the windows.

Dip the handle of a soft bristle brush into the solution, and then use the brush to wash down the windows. When you're finished, rinse the windows with a gentle spray of water from the hose. Do not spray the windows with a hard jet of water, as this may result in water reaching your home's interior.

Indoor Cleaning

To clean the inside of your home's windows, you'll need several soft microfiber cloths and a spray bottle filled with equal parts water and oxygen bleach. Again, if your window warranty prohibits the use of bleach, fill the spray bottle with vinegar without water. Follow this procedure:

  1. Spray the mildew with the solution or vinegar.
  2. Rub at the mildew with the microfiber cloth.
  3. Rinse the solution off of the window casings by wiping down the windows with a clean, damp microfiber cloth.
  4. Repeat steps one through three as necessary.


Mildew takes time and moisture to grow. The growth of mildew can often be prevented by increasing airflow around the windows, keeping the windows dry, and by cleaning the sash on a regular basis. To prevent mildew from growing on window interiors, run climate control or a dehumidifier throughout the year to keep the humidity levels in your home down.

To prevent mildew from growing on window exteriors, cut back bushes and shrubs that lock in moisture around the windows and prevent sunlight from reaching the window. In addition, keep your gutters clean and clog-free to prevent water from running down the side of your house during rainstorms.

Hello, my name is Valencia. Welcome to my website about windows. I want to share information about sourcing period-specific windows for your historical home. In many locations, historical societies will only issue renovation permits once the homeowner proves the materials are accurate to the build date of that structure. The windows must look and function exactly as they would new in that historical time period. My site will contain information about ordering, installing and maintaining these windows. I hope you will use the information on my site to keep your historical home in great shape through the decades. Thanks for visiting.
