How Often Should You Clean Windows in the Desert?

“Once or twice a year” is the usual advice for window cleaning — and in most parts of the country, that’s fine. It’s not in the Coachella Valley. Between blowing desert dust, hard water spots from sprinklers and monsoon rain, and near-constant sun exposure, windows here get dirty faster and the buildup is more stubborn than what you’d see almost anywhere else.

A good rule of thumb for the valley: exterior windows every 2-3 months, more often if you’re near a golf course, agricultural land, or a busy street where dust and overspray collect fast. Interior windows can usually go 2-3 times a year unless you have kids, pets, or south-facing glass that shows every smudge in direct sun.

Hard water is the bigger issue, though. Sprinkler overspray hitting windows day after day leaves the same mineral deposits you’d see on shower glass — and if it’s not wiped off regularly, it etches in the same way, leaving permanent spots that no cleaning schedule can fix after the fact. If your sprinklers hit your windows, that’s worth adjusting before it becomes a bigger problem.

We offer full-property window cleaning across La Quinta, Palm Desert, Palm Springs, Indian Wells, and the rest of the Coachella Valley — not just front-facing glass, but every window that gets hit by dust, sun, and sprinklers.
