WHEN A WASH IS NOT ENOUGH
Shine is not the same as clear.
Some buildup holds on through every regular cleaning. On glass like that, a maintenance wash can make it shine, but it stays visibly dirty until it is restored, and a squeegee will not clean it either.
Restoration is its own job. Lifts, water-fed poles and precision tools take on the detailed work, rope access goes where it is the right tool, and our drones fly a slower, stronger restoration clean on the glass they can reach. We set the mix once we have seen the glass.
One scope covers the elevated glass and the ground-level glass, so you are not lining up a second vendor for the lower floors.
