How to Clean and Maintain Fiberglass Windows

Proper care for your fiberglass windows is important! It ensures they will continue to perform and look their best. It also improves the longevity of your windows so you can continue to enjoy them for years to come. And because fiberglass windows are notoriously low maintenance, you can easily get the job done with a few simple routines. Here is a quick cleaning guide to help you keep your fiberglass windows in top shape.

Cleaning Supply List

Never use a power washer or harsh chemicals to clean any part of your windows. This can permanently damage the seals, laminate coatings, or finish. Here are the things you need to clean and maintain your fiberglass windows:

  • Sponge
  • Soft bristle brush
  • Dry towel
  • Mild detergent and water
  • Lint free cloths
  • Glass cleaner
  • Vacuum
  • Plastic putty knife
  • Silicone based lubricant
  1. Cleaning the Frame

Remove the screens and any window panes in preparation for cleaning. Then, mix together the mild soap and water to wipe down the frames. Use the sponge to gently clean the fiberglass and use the soft bristle brush for tougher dirt. Then use a cloth and clear water to rinse the frames and a towel to dry them. The biggest tip here is to work quickly so water does not drip down the frame. Too much soapy water can seep into the cracks and leaves stains, mold, or other problems down the road. And while you are cleaning look closely at your windows for signs of leaks, warping, rot, or damage so you can stay ahead of any major problems.

  1. Cleaning the Glass

Once the frames are clean, move on to the glass. Here you can use a standard glass cleaner or make your own solution of vinegar and water. And for a streak free clean, use lint free cloths or newspapers while cleaning the panes.

  1. Cleaning the Track

First, run the vacuum over the track to remove loose dirt and debris. And if something is wedged in the track, try using the plastic putty knife to remove it. When the track is clear, it is time to apply the silicone spray to ensure clean, smooth window operation. But don’t spray the lubricant directly into the track, or the overspray might get on your clean windows. Instead, spray into a towel and wipe it on the track. This will also help clear away any remaining dirt while also lubricating the track.

  1. Cleaning the Screen

This final step really helps cut down on the dirt and pollens entering your home. So when you remove the screens, be sure to put them on a flat surface or prop them up in the shower or bathtub. Then clean them using mild detergent and water. Rinse them off and allow them time to dry before re-installing the screens.
