Window Cleaning FAQs, answered by experts

The best homemade cleaning solution for windows is one gallon of warm, distilled or bottled water mixed with five to ten drops of liquid dish soap. This is what professional window cleaners typically use when they make their cleaning solutions. Using bottled or distilled water will help avoid hard water stains after cleaning, and the soap will cut through grease, smudges, and debris on your glass.

Yes, you can use glass cleaner on outside windows, but only after you’ve rinsed away as much debris as possible. Using glass cleaner on top of a layer of dirt will only make it harder to clean. 

Absolutely! We prioritize using eco-friendly, non-toxic products to ensure your home's and the environment's safety.

Professionals clean window screens the same way a homeowner can—by removing the screens and cleaning them with a sponge. A window cleaning pro may come with better equipment, like a high powered wet/dry vacuum or pressure washer to speed up the process and achieve a deeper clean.

You can use a commercial water repellent treatment for glass on your shower doors to prevent water spots. Take care to only apply the product to glass. Letting air circulate also helps prevent water spots, as water is less likely to remain on the glass for a long time with good air circulation. Run your vent fan, open a window, and leave the shower door open for about half an hour after using the shower.
