Spring Window Cleaning Checklist for Twin Cities Homeowners

Every Minnesota winter leaves a calling card on your windows: road salt spray, sand kicked up from the street, hard water spots from melting ice, and a gray film of grime you don't fully notice until the first bright spring morning. Spring is the single best time of year to reset your windows — the buildup is at its worst, the weather finally cooperates, and clean glass makes the whole house feel lighter just when you need it most. We've been doing spring cleanings across the Twin Cities since 1988, and over more than 12,000 homes we've settled on a routine that works. Here it is as a checklist you can follow yourself — plus a few honest notes on which steps are worth handing off.

Why Spring Is the Right Time

It comes down to what winter does to glass. Salt and sand don't just sit on the surface — salt is mildly corrosive, and left on windows and frames for months it can pit aluminum, degrade seals, and etch glass. Meltwater running off the roof carries minerals that dry into hard water spots, and those spots bond harder the longer they sit. A spring cleaning removes all of it before the damage becomes permanent, and it sets you up for the season when you'll actually be looking out the windows. If you clean your windows only once a year, spring is the time to do it.

Step 1: Inspect Before You Clean

Before any water touches the glass, walk the house and look at every window. Winter is hard on more than glass — freeze-thaw cycles work on caulk, seals, and frames all season. You're looking for cracked or missing caulk around the frames, weatherstripping that's torn or flattened, chipped paint or soft spots on wood frames, and fogging between the panes of double-pane windows. That last one matters: fog inside the glass means the seal has failed, and no amount of cleaning will fix it. Catching these problems in April or May gives you the whole summer to repair them before the next winter.

Step 2: Screens First

Screens collect a winter's worth of dust and grit, and if you wash the glass first, the next rain will rinse that dirt right back onto it. Pop the screens out, lay them flat on a driveway or deck, and wash both sides with a soft brush, mild soapy water, and a gentle rinse from the hose — never a pressure washer, which stretches and tears mesh. Let them dry completely before they go back in. While they're out, check for tears and bent frames; spring is the easiest time to get repairs done.

Step 3: Tracks, Sills, and Frames

The tracks are where winter really hides. Dead bugs, grit, and grime pack into the channels and keep windows from sliding smoothly. Vacuum the loose debris first with a brush attachment, then scrub the tracks with a small brush (an old toothbrush works) and soapy water, and wipe them dry. Wipe down the sills and frames while you're there. This is also the step almost everyone skips — and it's the difference between windows that look clean and windows that work like new.

Step 4: Wash the Glass

Now the part everyone pictures. The professional method is simpler than most people expect:

• Mix plain water with a small squirt of dish soap — skip the blue spray, and go easy on the soap since extra suds mean streaks
• Pick a cloudy, mild day, or work the shaded side of the house — direct sun flash-dries the solution and leaves streaks
• Wet the glass generously with a microfiber scrubber, working the edges and corners
• Squeegee top to bottom in overlapping strokes, wiping the blade after every pass
• Detail the edges with a dry microfiber cloth — no paper towels, which leave lint
• Tackle hard water spots with a 50/50 white vinegar and water mix; let it sit a few minutes before scrubbing gently

Inside glass gets the same treatment, minus the weather worries. One pro trick: use horizontal strokes inside and vertical outside, so if a streak shows up you'll know instantly which side it's on.

Step 5: Look Up — Gutters and Exterior

While you're outside with a ladder anyway, spring is the right moment to check what winter did to the rest of the exterior. Gutters clogged with the last of fall's leaves and winter's grit overflow onto siding and windows, undoing your cleaning work with every rain. Siding often carries a film of winter grime and the first green tinge of algae on the shaded north side. None of this is strictly window work — but it's all part of the same spring reset, and bundling it into one visit is usually cheaper than three separate ones.

The Checklist at a Glance

• Inspect caulk, seals, weatherstripping, and frames for winter damage
• Remove and wash screens; let them dry fully before reinstalling
• Vacuum and scrub window tracks; wipe sills and frames
• Wash exterior glass with the squeegee method on a cloudy day
• Wash interior glass, using a different stroke direction
• Treat hard water spots before they etch the glass
• Check gutters and siding while you're out there

Which Steps Are Worth Handing Off

Ground-floor glass, tracks, and screens are honest DIY territory — a free afternoon and a good squeegee will get you there. Where the math changes is height. Second-story windows mean ladder work, and ladders send thousands of homeowners to the emergency room every spring. It's also simply a lot of work: done properly, a full inside-and-out spring cleaning of an average two-story home takes most homeowners the better part of a weekend. Our crews do it in a few hours — screens, sills, and tracks included — with technicians who are OSHA, IWC, and BRC Aerial Lift certified, so nobody in your household has to leave the ground.
