Professional window cleaners rely on a combination of pure water systems for exterior high-reach work and a simple mixture of water and mild dish soap (like Dawn) for traditional hand washing. Their toolkit focuses on high-quality, long-lasting equipment designed for speed, streak-free results, and deep cleaning.
Dawn as a substitute glass cleaner
One of the most effective ways to clean glass is dish soap – it's what professional window cleaners use when cleaning exterior windows. Dish soap can remove stuck-on dirt and cuts any hazy build-up. It also works well on cloudy mirrors.
Professional window cleaners typically use concentrated, pH-neutral soaps mixed with water in a bucket, rather than ready-to-use sprays. The best pro solutions require high-quality lubrication for the squeegee and strong degreasing power to lift dirt, but without leaving a sticky residue that attracts future dust.
Choosing a Cleaning Solution
You would think you need a bunch of complicated chemicals and solutions for exterior window cleaning, but all you need is water and a mild detergent of some kind. Most industry professionals opt for dish soap.
Professional glass cleaners prioritize ammonia-free formulations that prevent streaks and protect window tints.

The vinegar cuts through grime and prevents water spots, while the Dawn cuts grease and provides the perfect lubrication for a squeegee to glide across the glass.

A professional window cleaner is not only responsible for making your panes shine but will also alert you to any potential issues. They also handle the heavy stuff, like climbing ladders and getting into hard-to-reach areas.
Most homeowners think that the best way to clean their windows is with a popular glass cleaner, but the best glass cleaning solution is a pre-mixed vinegar based solution that does not contain ammonia or alcohol. You can create your own vinegar solution by mixing one cup of white vinegar with 10 cups of water.
Start by mixing one part vinegar to 10 parts water in a spray bottle. Then, spray the solution onto the window and use a microfibre cloth to wipe away dirt and grime. For tougher stains, use a soft-bristled brush to scrub away the dirt. Once you've finished cleaning, use a squeegee to remove any excess liquid.

Degrease with hot water and dish soap, wipe with vertical/horizontal motions, and buff with a dry towel.
