Sanibel · Hard-Water Stain Removal
Hard-water stain removal on Sanibel Island.
Bonded salt and mineral spotting hand-lifted off Sanibel glass, where the heaviest daily salt load on the coast gets the longest run at an empty seasonal home.
Sanibel is the clearest case on this coast for treating bonded spotting as urgent rather than cosmetic. The island faces the Gulf broadside, so the daily salt load is about the heaviest anywhere we work, and a great many homes here sit closed for months with no one to notice what is happening to the glass. Salt lands, bakes on in the sun, gets rewetted by humidity overnight, and bakes again — which is exactly the cycle that drives mineral into a window surface rather than leaving it on top.
Our hard-water stain removal assesses each elevation, because on Sanibel the south-facing Gulf side is usually a different job from the north side of the same house. Bonded panes are worked by hand with fine 0000 steel wool and a mineral-cutting compound, then rinsed with pure deionized water so nothing is left behind to spot as it dries in the island sun.
The hard truth is that this is a race. Salt left through enough summers stops coming off and starts etching, and an etched pane is a replacement rather than a cleaning. Lifting it once and then holding it with recurring exterior window cleaning through the off-season is what keeps island glass out of that outcome. More on the island in Sanibel.
