Professional window washers use a variety of tools and solutions to clean windows, and different situations call for different techniques. For example, a high up exterior window may be very difficult to reach, so we employ an extendable water fed pole that delivers filtered water and gentle brushing to loosen dirt and other contaminants. For deeply stained windows, like those near the ground or a sprinkler outlet, we may employ a cleaning solution meant to deal with stuck on dirt, or hard water stains. Whatever the case may be, these tools allow us to remove dirt, grime, and residue from the glass surface, leaving behind a clear and streak-free result.
