Exterior window cleaning in Aqualane Shores.

Aqualane Shores is built around the canals that run off Naples Bay between Gordon Drive and the water, and the homes here are oriented to that view — wide bay-facing window walls, sliders onto dockside lanais, and tall glass that catches the morning sun off the canal. That orientation is exactly the problem: the same panes that frame the water also take the salt coming off the bay and the canal air that never really dries out, so the film lands on the largest, most visible glass in the house.

On a big view pane, every smudge and mineral spot shows from across the room, which is why the deionized rinse matters here more than almost anywhere. Our exterior window cleaning floods those large panels with pure water that carries no minerals, so they sheet dry with no spotting and no toweling marks across glass too wide to towel evenly. The upper-story bay glass on the two-story homes along 21st Avenue South is reached from the ground with the water-fed pole.

Constant canal air means buildup creeps back faster here than a few streets inland, so the every-two-month rhythm is what keeps it ahead. For panes near the bay that have already spotted, our hard-water stain removal lifts the deposit before the plan takes over. More on the area in Aqualane Shores.
