Ask ten Minnesota homeowners when they last cleaned their windows and you'll get ten different answers — usually some version of "I don't remember." That's understandable. We have four sharply different seasons, and each one creates its own kind of mess on your glass. Knowing the best time to clean windows in Minnesota isn't just about aesthetics; it's about timing the work so it actually lasts.

Here's how to plan your seasonal window cleaning schedule around the Twin Cities calendar — and which months we recommend most often to our customers.

Spring (April–May): The #1 Time to Clean

If you only clean your windows once a year, spring is the season. After five months of snow, ice, road salt spray, and stagnant winter air, your windows are at their worst — and the warm-up means screens can finally be reinstalled and outdoor cleaning becomes safe again. April to mid-May is peak booking season at A+ Window Cleaning for exactly this reason.

What spring cleaning addresses:

Summer (June–August): The Maintenance Window

Summer is when lawn sprinklers, thunderstorms, and lake spray do their damage. If you have an irrigation system that sprays your first-floor windows daily, you'll likely want a mid-summer touch-up to head off hard water stains before they etch into the glass. This is also the season when commercial storefronts get hit hardest — outdoor dust, pollen, and bug residue accumulate fast in the heat.

A common Minnesota mistake is scheduling cleaning on a 95° sunny day. Don't — the cleaning solution evaporates before you can squeegee, leaving streaks. Cloudy days or early mornings give the best result.

Fall (September–October): Critical Before Winter

Fall cleaning is non-negotiable if you want clear views all winter. October is our second-busiest month for a reason — by November, falling leaves stick to wet glass, gutters overflow, and cold air makes professional cleaning much harder. Get your windows done in September or early October, and you'll head into the dark months with maximum daylight reaching your interior.

Bonus: fall is when most Minnesota homeowners install storm windows. Cleaning the regular pane before the storm goes over it is the only way to actually see clearly until spring.

Winter (November–March): Limited, but Possible

Most window cleaners shut down outdoor service when temperatures drop below 40°F — the water solutions freeze on contact. But interior cleaning is fair game year-round, and demand is much lower, so booking is fast. If you host through the holidays and want your interior glass spotless, December and January are surprisingly good months to call.

The Ideal Schedule for Most Twin Cities Homes

For most Minneapolis and St. Paul homeowners, here's the simplest rhythm we recommend:

That's two visits a year for most homes, which puts you on a recurring discount and keeps your windows looking professional year-round.
