City of Mesa Water Resources delivers water to Mesa from mixed source at 335 mg/L (CaCO₃). That is extremely hard for a US municipal supply. On Mesa glass that residency means visible spotting on dark glazing within a single dry-down cycle and accelerated lower-sash mineral residue over the working year. The local operating practice is a citric pre-treatment followed by a citric finish-rinse on long-residence glass, and a deionized rinse on heritage and high-value stock where chemistry matters most.

March through early May is the second peak season after monsoon-recovery in October. Manage pollen passes and lawn-treatment overspray.
Reduce or suspend midday work above 105°F ambient. Shift to early-morning routes; consider a heat-load-tolerant solution variant (Jerry Davenport's variant works here).
Mid-September through November is the highest-volume cleaning window of the year. Post-monsoon dust recovery drives the call list.
Steady residential work November through February. Freezing nights in the high country pause those markets; Phoenix and Tucson run normally.
Fine red-tan dust deposited during haboobs and convective storms. Hygroscopic — it pulls moisture from the air and re-bonds to glass overnight, producing the characteristic morning-after streak pattern.
Stucco-trim irrigation systems routinely throw water onto adjacent glass. At 300+ mg/L hardness and 115°F evaporative load, each pass deposits a measurable mineral ring. Untreated for a season, this etches.
Mesa runs at 335 mg/L (CaCO₃) on City of Mesa Water Resources a mixed surface-and-groundwater blend — extremely hard, meaning municipal water deposits mineral residue on every exposed pane, accelerates long-term etching, and cannot be the last thing that touches the glass — most cleaners at this level run a deionized rinse.
