Clear Solutions to Dirty Window Problems

Here’s how to make washing windows easier and more efficient.

If your windows always streak after washing, steal this tip from the pros. Use a window-washing squeegee with a smooth, soft rubber edge (or crumpled-up black-and-white newspaper – avoid the colour sections). Dry a 2.5 cm strip at the top or side of each window and always start your squeegee there. Starting on dry glass is one key to avoiding streaks. Don’t wash windows in direct sunlight, because glass that dries quickly is more susceptible to streaking. Cloudy days are best for window washing.

If there’s mildew on your window frames, wash with a bleach-detergent solution. Black or grey mildew spots on wooden frames can be cleaned with a solution of 60 ml of household bleach and 30 ml of laundry detergent in a litre of water. Wearing rubber gloves to protect your hands, sponge the solution onto the spots, let it sit for ten minutes, and then rinse thoroughly with clean water.

If you can’t keep the outside windowsills clean, apply a coat of floor wax to protect your sills.

If your blinds are always dusty, use an anti-static spray. The best way to keep dust from piling up quickly is by applying the spray on the blinds right after you clean them.

If your windows get dirty unusually fast, change the filter in your heating and cooling system. While airconditioner filters extend the life of your appliances, they also help trap dirt. Filters should be changed every month or two, or any time you can’t see through the filter when you hold it up to a light.
