Window Cleaning Methods Compared (2026) | Total Wash Co

Quick answer: For exterior windows, professionals use two main methods: a water-fed pole with purified water for upper stories and full-house exteriors, and the classic mop-and-squeegee for ground-floor and interior glass. Pressure washing glass is never the right call. [In Madison](/blog/moss-algae-roof-treatment-madison-spring-timing), professional window cleaning starts at $199, with most homes landing between $199 and $450.

Hi — Ashton Ferry here, owner of The Total Wash Co. in Madison. Since 2021 I've cleaned windows on everything from downtown condos to three-story lake houses, and one of the most common questions I get at the door is some version of: "So do you squeegee all of these... or spray them... how does this actually work?" Fair question, because the answer changes based on the glass, the height, and — this matters a lot in Madison — our famously hard water. This guide compares every exterior window cleaning method honestly: what we use, when we use it, what each costs, and the one method you should never let anyone use on your windows. If you just want the bottom line on pricing, our residential window cleaning starts at $199, most Madison homes run $199–$450, and larger homes with full inside-and-out service range up to $795.

What Are the Main Ways to Clean Exterior Windows?

Every window cleaning approach you'll ever see falls into one of four buckets:

• Mop and squeegee — the traditional method: soap solution applied with a scrubber (the "mop"), pulled off with a rubber squeegee blade, edges detailed with a towel. Done by hand, up close.
• Water-fed pole (pure water) — a telescoping pole with a soft brush head that scrubs the glass while purified, mineral-free water rinses it. The window air-dries spot-free because there's nothing dissolved in the water to leave a spot. Reaches second and third stories from the ground.
• Soft washing — a low-pressure application of a cleaning solution (typically a sodium hypochlorite mix). This is a house and roof cleaning method, not a glass-polishing method — but it plays a real supporting role, which I'll explain below.
• Pressure washing — high-pressure water. Great for concrete. On windows? Never. I'll show you why.

A good company doesn't pick one method and force it on every job — we carry all of the above on the truck and match the tool to the glass.

Should You Ever Pressure Wash Your Windows?

No. And I want to be specific about why, because every summer we see the aftermath of someone "quickly hitting the windows" while pressure washing their siding:

• Blown window seals. Modern double-pane windows are two sheets of glass sealed around an insulating gas layer. Concentrated high pressure can compromise that perimeter seal — and once it fails, moisture gets between the panes and you get permanent fogging you cannot clean. That's a glass-replacement bill, not a cleaning bill.
• Water forced where water shouldn't go. Window frames, weep holes, and sills are designed to shed rain falling downward — not a pressurized stream driven sideways or upward. Water driven into the frame ends up in the wall cavity.
• Shredded screens and damaged glazing. Older Madison homes — think the 1920s bungalows around Vilas and the near-east side — often have original glazing putty that high pressure chews right off.
• And the kicker: the glass still won't look clean. Untreated tap water blasted at glass dries with mineral spots everywhere. You risk hundreds of dollars in damage to get windows that look worse.

When we pressure wash a house exterior or soft wash siding, the windows get rinsed as part of the process — gently, top-down, low pressure — and then cleaned properly as their own step. High pressure aimed at glass is the one hard "never" in this industry.

What Is Water-Fed Pole (Pure Water) Window Cleaning?

This is the method that surprises people the most, and it's our workhorse for exterior glass. Here's how it works:

• We run regular water through a purification system that strips out all the dissolved minerals. We're aiming for near-zero on a TDS (total dissolved solids) meter — essentially laboratory-pure water.
• That pure water feeds up a telescoping pole to a soft-bristle brush head, which scrubs the dirt, pollen, and grime loose while the water flows.
• We rinse the pane top to bottom and just... walk away. No squeegee, no towel. Because the water has nothing dissolved in it, it dries with zero spots and zero streaks.

Why this matters extra in Madison: our municipal water is hard — loaded with dissolved calcium and magnesium from the aquifer. It's why your shower door spots up and why hosing off your own windows always leaves them looking chalky. If you've ever DIY-rinsed your windows and watched them dry worse than they started, hard water is the culprit. (If spots have already baked onto your glass over the years, that's a different service — see our guide to removing hard water stains from windows.)

The other huge advantage: reach. Our water-fed poles clean up to three stories from the ground. That means no ladders leaning against your siding or gutters, no boot marks on the roof, and safer jobs — which is exactly why insurance-conscious companies have shifted to this method for upper floors. On the tall colonials in Maple Bluff and Shorewood Hills, the pole system cleans gable-end windows that a ladder crew would struggle to reach safely at all.

The honest limitations: pure water cleaning needs unobstructed glass to shine — heavy paint overspray, stickers, or years of baked-on grime need hand detailing first. And it's an exterior-only method; nobody's running a water-fed pole across your living room.

When Is the Classic Squeegee Still the Best Tool?

The squeegee isn't obsolete — not even close. We still hand-squeegee every job, every week. It wins in these situations:

• All interior glass. Inside your home it's the only professional method: a light soap solution, a scrub, a clean squeegee pull, and detailed edges. Controlled, drip-free, and it leaves that crisp, polished look.
• Ground-floor exterior detail work. Front-door glass, storm doors, and picture windows you see up close every day benefit from the hand finish.
• Heavily soiled first passes. Construction dust, screen "shadow" burn, bug debris — agitation by hand beats any brush head.
• French panes and storm windows. Older Madison homes are full of divided-lite windows and removable storm inserts. Those small panes are hand work, full stop.

The tradeoff is time and access: squeegee work above the first floor means ladders, and ladders mean slower jobs, higher cost, and more risk to your landscaping and siding. That's why the modern standard is a combination: water-fed pole for upper exteriors, squeegee for interiors and ground-level detail. That's exactly how we run most homes.

Is "Soft Washing" Windows a Real Method?

You'll see companies advertise "soft wash window cleaning," and it deserves a straight answer because the term gets misused.

Soft washing is a house-washing method — a gentle, low-pressure application of a cleaning solution that kills and removes the organic growth (algae, mildew, spider webbing) on siding, soffits, and trim. It's what we use to wash vinyl and Hardie board homes all over Dane County, and it's fantastic at what it does. If you want the deep dive, here's our full explainer on soft [washing in Madison](/blog/vinyl-siding-washing-madison).

But soft wash solution is not a glass finish. Detergents dry on glass; solution residue leaves a film. So on a full house wash, the correct sequence — and the one we follow — is:

• 1. Soft wash the siding and trim (windows get solution on them — that's expected and fine).
• 2. Rinse everything thoroughly, top down.
• 3. Finish the glass with a pure-water scrub and rinse so the windows dry spot-free.

If a company soft washes your house and skips step 3, you'll have clean siding and cloudy windows. When you're comparing house-wash quotes, ask specifically: "Is a proper window rinse included, or is window cleaning an add-on?" It's one of the clearest ways to separate detail-focused companies from spray-and-go outfits.

Which Window Cleaning Method Is Right for Your Madison Home?

Here's how I'd match method to house, based on what we see across the area:

• Two- and three-story homes (Maple Bluff, Shorewood Hills, west-side colonials): water-fed pole exterior + squeegee interior. Safest and most thorough combination, no ladders on your siding.
• Newer builds in Waunakee, Sun Prairie, and Verona: mostly vinyl windows with removable screens — a straightforward pole-and-squeegee combo job. Great candidates for a recurring schedule since the glass is easy to maintain once it's been detailed properly.
• Lake-facing homes on Monona or Mendota: expect more frequent cleanings — spray, humidity, and insect activity work the lake side of the house harder than the street side. Twice a year keeps them genuinely clear.
• 1920s–40s character homes (Vilas, Dudgeon-Monroe, near-east side): divided lites and storm windows mean more hand work. Worth hiring someone who'll take storms out and clean both sides rather than skipping them.
• Post-construction or first-ever professional clean: budget extra for the first visit — debris removal, sticker residue, and paint specks are restoration work. Every visit after that is faster and cheaper.

How Much Does Each Method Cost in Madison?

Method matters less to the price than pane count, stories, and condition — but here's the honest lay of the land:

• Professional window cleaning (any method): starts at $199 with us; most Madison-area homes land between $199 and $450. Larger homes getting the full interior + exterior + screens + tracks treatment run up to $795.
• Exterior-only pure-water service is the most economical way to keep a home looking sharp between full cleans — no interior access needed, so it's also the easiest to schedule.
• DIY squeegee kit: $40–$80 in decent tools, plus your Saturday, plus a ladder for anything above the first floor — which is exactly where I'd gently point out that homeowner ladder injuries are a real emergency-room statistic. Ground floor DIY? Go for it. Second story? Please call somebody, it doesn't have to be us.
• Add-ons worth knowing about: screen cleaning and repair, track and sill deep cleans, storm window service, and our quarterly protective coating that helps glass stay cleaner longer between visits.

Frequently Asked Questions About Window Cleaning Methods

Can I use a pressure washer on my first-floor windows if I'm careful?

I'd still say no. Even at reduced pressure, you're driving water at seals and frames designed for falling rain, and untreated tap water will dry spotty anyway. If you want to DIY exterior glass, a bucket, a strip washer, and a squeegee will beat a pressure washer every single time — on results and on risk.

Why do my windows look worse after I rinse them with the hose?

Madison's hard water. Every drop of tap water carries dissolved minerals, and when the drop evaporates, the minerals stay behind as white spots. Professional pure-water systems strip those minerals out before the water ever touches your glass, which is why our rinse dries invisible and yours doesn't. It's not your technique — it's the water.

Does the water-fed pole actually clean as well as a squeegee, or is it just faster?

On routine maintenance cleans, the results are equal — the brush agitation plus pure-water rinse removes everything a squeegee would. Where hand work still wins is heavy restoration: baked-on grime, paint, hard-water staining, and construction debris need hand detailing first. That's why we bring both to every job.

Do you clean screens and tracks too, or just the glass?

Both, and I'd argue the tracks are half the transformation. Our full service includes screens removed and hand-washed, tracks and sills detailed, and interior glass squeegeed. Clean glass with filthy tracks is like a car wash that skips the wheels.

What happens if it rains right after my windows are cleaned?

Usually nothing — rain itself is fairly clean water. What makes windows dirty after rain is what the rain splashes onto the glass or what it picks up running down dirty siding or screens. Since a proper clean deals with all of that, professionally cleaned windows typically shrug off a rainstorm just fine.

Can you clean windows year-round [in Wisconsin](/blog/how-often-clean-gutters-wisconsin), or only in summer?

Year-round, with a little judgment. Pure-water systems and squeegee work are both fine well into fall, and on milder winter days we clean exteriors with an additive that keeps the rinse water from freezing on the glass. Deep winter is honestly better spent on interior glass, tracks, and screens — then we hit the exteriors first thing in spring once the pollen settles. If you're on a twice-a-year schedule, late spring and early fall are the two appointments I'd protect.
