What changes the right cleaning schedule?
Distance from salt water, prevailing wind, irrigation overspray, tree cover, construction dust, and the direction your glass faces all matter. A protected Palm City home and an exposed Hutchinson Island condominium should not be placed on the same schedule.
A useful Treasure Coast rule of thumb
Start monthly for exposed exterior glass, every two months for a typical residential exterior, and quarterly for interior panes. If the view looks hazy before the next appointment, shorten the interval. If it still looks excellent, extend it.
Why exterior-first service is usually enough
Salt, pollen, rain residue, insects, and landscaping collect outside much faster than inside. An exterior-only visit keeps the view clear without requiring anyone to be home, while interior service can be added when fingerprints and household film become noticeable.
