Spring in Utah hits hard. Snow melt drains down siding leaving mineral streaks, freeze-thaw cycles pulled silt and grit into your window tracks, pollen counts jump in April-May, and the wind storms that blow through Salt Lake at the equinox layer canyon dust across everything south-facing. By late April most Utah windows look noticeably worse than they did in February, even if you cleaned them in the fall.
This is the most important window cleaning you'll do all year. Get it right and your windows stay looking sharp through summer's heavy sprinkler season. Skip it and you're fighting buildup that gets harder to remove every month.
Here's the full checklist — from the inside-out cleaning to the things you should fix once and never touch again.
The sweet spot is late April through mid-May in the Salt Lake Valley. Three reasons:
If you only do windows once a year, do it now. If you do them twice, this is the first round and fall is the second.
Before grabbing any tools, walk the perimeter of your house and note:
Write down what you find. You'll work from this list.
Screens trap pollen, dust, and bug residue all winter. If you clean windows without removing screens, you're cleaning around the dirty source and the next breeze re-deposits everything.
More on this in our screen cleaning guide.
Standard pro technique. We covered this in detail in DIY vs. professional window cleaning.
If you see white spots, arcs, or chalky haze from sprinkler overspray:
If vinegar isn't enough, escalate to citric acid paste (2 tablespoons food-grade citric powder in 1 cup distilled water). For severe deposits, see our full hard water stain removal service — DIY can only do so much on multi-year buildup.
Tracks accumulate the worst grime over winter. Pollen, dirt, dead insects, melted snow that re-froze and pulled debris in.
Skip this step and your windows look clean but your house looks unmaintained from up close.
Interior sills collect dust. Exterior sills collect everything from leaf debris to bird droppings. A quick microfiber wipe (or a Magic Eraser for stubborn marks) every spring keeps them looking fresh.
Interior windows are easier — no weather, no hard water, no ladders. But save them for last because:
Use the same strip washer + squeegee technique. Pure water + a few drops of soap. Wipe edges with microfiber.
These only need to happen once a year. Spring is the right time.
Salt Lake County water averages 16 grains-per-gallon of hardness (national average is 7). Every sprinkler drop that hits your window will leave minerals when it dries. Walk your yard during a manual cycle of each zone, and:
This single afternoon of sprinkler tuning prevents 80% of the hard water staining that plagues Utah homes. Most of what we treat in our hard water stain removal work could have been prevented with this step.
Spring cleaning is the ideal time to apply a hydrophobic coating because the glass is freshly stripped and ready to bond. Options:
Sealers make water bead and roll off the glass instead of sitting and evaporating in place. That's the difference between needing a fall cleaning and having windows that still look great in October.
While they're off and drying, look for:
A torn screen lets bugs in all summer. Replacing during spring cleaning is much easier than trying to fix it in July with the screen reinstalled.
Run a candle or stick of incense along the edges of windows on a calm day. If the smoke or flame flickers, you have air leaks. Fix with weatherstripping or caulk before AC season starts. This isn't strictly cleaning but it's a great spring task while you're at the window anyway.
We see these every May:
DIY spring cleaning is realistic if:
Hire a pro if:
Spring is our busiest season for a reason. Book by mid-April for best availability — we're usually a week out by May 1.

Every job is quoted in person — Utah homes vary too much for accurate phone pricing.
Late April to mid-May for most of the Salt Lake Valley. Pollen has slowed, snow melt has stopped, and spring wind storms are mostly done. Cleaning earlier risks more spring weather messing it up; cleaning later misses the pre-summer window where you want everything pristine before sprinklers turn on heavy.
Exterior first. Always. Exterior cleaning kicks up dust, and you don't want that landing on already-clean interior glass. Plus exterior work involves screens being off, ladders out, hoses connected — get all the messy stuff done first.
No. Pressure washers can damage window seals, push water past gaskets into the wall cavity, and crack older glass with thermal shock. Use a hose with a regular nozzle, never above shoulder pressure. Water-fed poles with soft brushes are the safe alternative for upper-story windows.
For an average two-story Salt Lake home with moderate spring buildup: 60-90 minutes for a two-person crew. Includes exterior + interior, screens removed and washed, tracks and sills wiped, and a quick walk-through. Hard water restoration adds another 30-60 minutes if needed.
In Utah, yes. The combination of high mineral water, low humidity, and heavy summer UV bakes deposits onto glass faster than almost anywhere in the country. A sealer applied in spring keeps water beading off through the worst of summer. Without one, expect mineral buildup to start within weeks of your spring clean.
