Washing your windows doesn’t have to be an ordeal if you’re armed with the right tools and know the techniques used by professional window cleaners. There’s no magic involved and you can get the same beautiful, streak-free results as the pros.
Professional window washers provide an exceptional level of clean and they don’t waste time achieving their goal. Forget fancy cleaners and other home methods that are “guaranteed” to work. If they were really effective, the professionals would be using them.
The best cleaning solution is to use a small amount of ordinary dish soap in plain water. Use warm, not scalding hot water. You can buy pre-made solutions if you want, but refrain from using glass cleaners that contain alcohol or ammonia.
Many commercial window cleaning liquids claim to be streak free, but they’re really not. Depending on the ingredients, commercial formulas can also leave behind a thin film that you’ll later discover attracts dust. Even worse, the cleaners may also attract moisture that can create a damp film on windows under the right conditions.
Things That Stick
There are any number of materials that can collect on the inside of window glass and they can be difficult to remove. Whatever you do, never use a razor blade, knife blade or other objects to scrape off stubborn, stuck-on material. If you find something that doesn’t want to come off, it can be helpful to use a solvent such as rubbing alcohol or acetate to remove it before proceeding with the cleaning.
Ideally, use a microfiber cloth for the washing phase of your window cleaning that’s been soaked in your dish soap and water solution. The material is soft, lint-free, and won’t scratch the glass. A lambswool cleaning cloth or mitt such as the one used for vehicles is also a good choice, as is a chenille cloth or mitt.
A squeegee isn’t just for windows on the outside. They’re also effective indoors for removing liquid. You’ll need to place a cloth on the floor at the bottom of the windows, since there will be dripping. Start at the top of the window and work your way down, moving the squeegee from one side to the other. Wipe off the squeegee after each pass to prevent the transfer of dirt and grime back to the window. Finish with a soft, dry cloth – or a paper towel in a pinch – to remove any moisture from window corners.
