How to Repair Aluminum Storm/Screen Windows
Keep screens clean
- 1). Remove screens yearly. Lay them on a flat surface to clean them with a soft-bristle brush. Then stand them up to rinse them with a fine spray from a garden hose.
- 2). Clean the outside of storm windows from the ground, using a garden-hose cleaning attachment.
- 3). Remove the storm windows from the inside for simultaneous interior and exterior cleaning. Typically you'll need to do this less often because the inside surface is protected.
