The Jo Burg

Window cleaning doesn’t have to be a panicked Saturday spent chasing streaks while the sun bakes soap onto the glass.

A seasonal cadence, done on purpose, keeps grime thin, predictable, and easy to remove. And the weird bonus? Your house looks “maintained” even when the rest of life isn’t.

 

 The real problem: you’re cleaning too late

Most people don’t have a window-cleaning problem. They have a timing problem.

When you wait until the glass looks terrible, you’re not cleaning anymore, you’re restoring. That’s when you scrub harder, re-wipe edges, fight mineral spots, and burn an hour just on tracks that should’ve taken five minutes.

Here’s the thing: windows get dirty in patterns. Pollen season. Summer dust and sprinkler mist. Fall debris. Winter film from condensation and heating. If you’ve ever wondered when is the best time to clean your windows, the answer usually comes down to matching the work to those patterns, and when you do, you win.

 

 The cadence (simple, not precious)

Forget a rigid calendar. Tie the work to seasons and add a tiny “maintenance heartbeat” so you’re never starting from zero.

Your rhythm:

– Daily/As-needed: quick spot-checks (fingerprints, dog nose art, kitchen splatter)

– Monthly: a rotating set of “overlooked” tasks (tracks, sills, one set of exterior panes)

– Seasonally: the bigger reset jobs that keep the whole system from slipping

That’s it. No gold star required.

 

 Spring: pollen is the enemy, screens are the battlefield

Spring cleaning is less about sparkle and more about containment. Pollen sticks to screens and frames, then gets dragged indoors every time you open a window or door.

 Pollen prevention (before you touch the glass)

Walk the exterior perimeter first. I mean literally walk it. Look at:

– gaps in weatherstripping

– cracked caulk at trim joints

– screen corners that aren’t seated tightly

Seal the obvious leaks, because you can’t “clean” your way out of a drafty frame that’s constantly inviting dust inside.

Now, this won’t apply to everyone, but if you live near heavy landscaping or flowering shrubs, moving or trimming plants away from windows makes a noticeable difference. I’ve seen homes cut visible pollen buildup just by clearing a 12, 18 inch zone around lower windows.

 

 Screens: clean them like they matter (because they do)

Pull screens out. Inspect for tears. Then:

1. Dry remove first: shake, brush, or vacuum (soft brush attachment)
2. Wash: mild soap + lukewarm water, gentle sponge or soft brush
3. Rinse thoroughly: leftover soap is a streak factory
4. Dry fully: re-installing damp screens is how you end up with trapped grit and musty corners

If your screens are old aluminum and slightly oxidized, don’t go aggressive. You’ll grind oxidation into the mesh and it’ll look cloudy forever.

 

 Sills and stains

Painted sills handle mild all-purpose cleaners fine. Bare wood doesn’t. For wood interiors, use the least-wet method possible: damp microfiber, wipe along the grain, then dry immediately.

Stains that don’t budge? Test a gentle solvent in an inconspicuous spot (yes, it’s annoying, but repainting is more annoying).

One-line truth: Spring is where you prevent the whole year’s buildup.

 

 Summer: quick hits, glare, and condensation weirdness

Hot take: Summer is the easiest season to maintain windows and the hardest season to deep clean them well.

Why? Heat. Direct sun. Fast evaporation. That’s how you get streaks that “appear” after everything looked fine.

So summer is for shorter sessions. Earlier in the day. Shaded sides of the home first.

 

 Glare control (practical, not aesthetic)

Clean exterior glass on big, light-facing windows and trim back foliage that’s rubbing or shedding onto panes. Plants touching windows cause micro-scratches over time (especially when wind-driven dust gets involved).

If glare is a constant issue, window film can help, but it changes your maintenance slightly. Film tends to show edge residue and smudges faster, so you’ll want softer cloths and gentler products. No ammonia on many films. Read the manufacturer guidance or you’ll shorten its life.

 

 Condensation checks

Condensation on the interior in summer often points to:

– poor air circulation near windows

– seals starting to fail

– humidity spikes from cooking, showers, basements

Look closely at the bottom edge of frames and the corners. That’s where problems start. Replace worn gaskets if you can; otherwise, at least clean and keep the area dry so you’re not feeding mildew.

 

 Fall: the “seal and dust” season (unsexy, extremely effective)

Fall is when I get opinionated: if you skip fall, winter will punish you.

This is the season for tightening up the building envelope and knocking out interior dust zones that get worse once the heat kicks on.

 

 What actually matters in fall

– Inspect caulk lines and weatherstripping; repair obvious gaps

– Clean tracks and weep holes (those tiny drain channels) so water can escape

– Wipe blinds and ledges before you close windows for the season

Dust loves warm air currents. Once heating starts, you’ll see it settle on sills and lower panes like it’s paying rent.

Also, do a basic exterior visibility pass: trim shrubs, check exterior lighting, clear cobwebs from corners. Your windows will look cleaner just from better sightlines and less shadowy grime.

 

 Winter: streak-free cleaning and “don’t freeze your seals”

Winter window cleaning is about restraint. A little moisture, done carefully, beats soaking anything.

Use a gentle, ammonia-free cleaner and microfiber cloths. Work small sections. Dry immediately. If the glass is cold, even good cleaner can smear if you over-apply.

Look, don’t crank the heat to “surface of the sun” right before cleaning. Rapid temperature swings can stress seals, and condensation will undo your work anyway.

 

 One surprisingly useful stat

Indoor humidity is a big driver of winter condensation. ASHRAE guidance commonly targets ~30, 60% relative humidity for comfort in occupied buildings, with lower levels often needed in cold weather to reduce condensation risk. Source: ASHRAE thermal comfort and indoor environmental quality guidance (ASHRAE, Standards and Handbooks overview: https://www.ashrae.org/).

Translation: if your windows keep fogging up, cleaning is only half the fix.

 

 Tools that actually save time (not gimmicks)

You don’t need a closet of gadgets. You need three things that aren’t junk.

A good setup:

– Squeegee (quality rubber): the fastest path to streak-free glass

– Microfiber cloths (two types): one for washing, one for final drying/buffing

– Extension pole: reach upper panes without ladder gymnastics

Add a small detailing brush for frames/tracks if you want to feel like a pro (it helps). Keep a spray bottle with a mild solution and resist the urge to over-soap.

In my experience, most streak problems aren’t product problems. They’re “too much liquid + not enough drying cloth” problems.

 

 Build a bite-sized schedule you’ll stick with

If you try to “do all the windows” in one go, you’ll treat it like a once-a-year punishment. Instead, rotate.

Here’s a pattern that works in normal human life:

– Week A (20, 30 minutes): interior glass on the busiest windows

– Week B (20, 30 minutes): exterior glass on those same windows

– Once a month (15 minutes): tracks + sills on a small zone (kitchen, entry, living room)

That rotation keeps visibility high where you actually look, while slowly sweeping the whole house into shape.

One-line reminder: Momentum beats intensity.

 

 When the plan breaks (because it will)

If you fall behind, don’t “catch up” by doing everything. That’s how you quit again.

Do this instead:

– reset just the front-facing windows for curb appeal

– clean one room’s interior panes for morale

– handle tracks on the worst two windows (they cause half the mess)

And keep a small caddy ready to go. The time you waste hunting for a squeegee is the time your brain decides this task is annoying.

That’s the whole trick, honestly: make it easy enough that you don’t negotiate with yourself.

Pressure washing looks simple right up until it isn’t.

A good rinse turns into shredded wood fibers, etched concrete, water behind siding, or a tripped breaker because someone blasted the meter box like it was a patio chair.

So where’s the line between “DIY pride” and “call someone with insurance”?

Hot take: most people don’t need “more pressure.” They need more patience.

I’ve watched homeowners rent a 3,200 PSI unit and immediately reach for the red 0° tip like it’s a cheat code. It’s not. It’s a tiny water chisel.

Here’s the thing: if you’re asking What Is Pressure Washing?, cleaning power comes from a mix of PSI (pressure), GPM (flow), chemistry, and dwell time. Pros lean on flow and technique. DIYers tend to crank pressure because it feels productive.

The “Safe DIY” List (if you can follow directions)

If you can commit to testing a small area and you’re willing to stop when something feels off, you can handle plenty of exterior cleaning yourself.

Good DIY candidates

– Sidewalks and plain broom-finish concrete (no decorative overlay, no fresh pour, no failing sealer)

– Vinyl siding that’s firmly attached and not already brittle (use low pressure; rely on detergent)

– Composite decking that’s in good shape (wide fan tip, keep distance, don’t stripe it)

– Outdoor furniture, plastic bins, garage doors (easy wins)

– Fences *only if you accept* some fuzzing risk and you use a gentle approach

Short version: if the surface is tough, flat, low-to-the-ground, and not historically valuable, DIY is usually reasonable.

DIY technique, but not the fluff version

A few rules that actually prevent damage:

Use the lowest effective pressure.

If you can clean it at 1,500, 2,000 PSI, cleaning it at 3,000 PSI isn’t “better,” it’s just faster… until it isn’t.

Stand back. Then back up more.

Distance is your real pressure regulator. Start farther than you think you need, then creep in.

Keep the wand moving.

Pausing for even half a second is how you carve tiger stripes into wood and “engrave” concrete.

Don’t spray upward into laps and seams.

That’s how water gets behind siding, under trim, into soffits, and suddenly you’re researching mildew remediation at 11 p.m.

One more: detergents aren’t decoration. Let them dwell (but don’t let them dry).

A quick stat that should change how you think about this

Consumer-grade pressure washers often deliver 1.2, 2.0 GPM, while professional units commonly run 4+ GPM. That higher flow is a big reason pros can clean faster at lower pressure. The Pressure Washer Manufacturers’ Association (PWMA) even emphasizes comparing machines using Cleaning Units (CU = PSI × GPM) rather than PSI alone. Source: PWMA consumer guidance on pressure washer ratings and CU.

Translation: the pro’s machine isn’t just “stronger,” it’s *different*.

When you should hire a pro (because the downside is ugly)

Some jobs are risky even if you’re careful. Not because you’re incompetent, but because the materials, height, or consequences are unforgiving.

Call a professional when you’re dealing with:

1) Height + water + ladders

Two-story siding, steep roofs, awkward dormers. If you’re on a ladder with a pressurized wand, you’re already in the danger zone (and I’m not being dramatic).

2) Roof cleaning

Most roofs shouldn’t be pressure washed at all. Asphalt shingles especially. Proper roof cleaning is typically low-pressure chemical application with controlled rinse, and overspray management is half the battle.

3) Old wood, soft brick, historic masonry

Aged substrates fail quietly. You won’t always see damage immediately; sometimes you “clean” it and accelerate deterioration.

4) Anything near electrical service

Meters, weather heads, service masts, exterior panels, outlets, lighting, doorbell transformers. Water intrusion here is the kind of problem that ruins your week.

5) Peeling paint or mystery coatings

If there’s a chance you’re disturbing old lead paint, you don’t want to freestyle it. Same story with unknown sealers that turn cloudy or strip unevenly.

6) Oil stains, rust, efflorescence that won’t quit

Stain removal often needs heat, specialty chemicals, agitation, or multiple controlled passes. The DIY approach is usually “more pressure,” which is how concrete ends up etched and still stained.

The real DIY vs. pro cost comparison (the part nobody wants to calculate)

DIY is cheaper on paper. Then the receipts happen.

– Rental unit: daily fee + deposit

– Detergent, pump protector, hoses, tips you didn’t know you needed

– Landscaping you accidentally nuked with overspray

– Time: setup, testing, moving furniture, cleanup, return trip

– The big one: damage risk

Now, this won’t apply to everyone, but if you’re the type to “push through” when the result looks uneven, you’re a prime candidate for costly rework. Pros aren’t magical. They’re just operating with better flow rates, surface-specific chemicals, and a lot more reps.

Also: insurance matters. If a contractor cracks a window seal or forces water behind a wall, there’s a process. If you do it, that process is called “paying for it.”

Gear talk: DIY machines vs. pro rigs (what’s actually different)

DIY machines can be fine. I’m not anti-consumer tools. I’m anti-expecting them to behave like commercial equipment.

Professional setups typically bring:

– higher, steadier GPM

– better pressure regulation and unloaders

– downstream or dedicated chemical systems

– surface cleaners that don’t leave zebra stripes

– hot water capability (for grease and gum)

– consistent maintenance and backup parts (which is boring… until it saves a job)

And yes, technique is huge. A mediocre washer in skilled hands beats a powerful washer used like a firehose.

Surfaces & hazards: what goes wrong fast

Concrete is “tough,” but it isn’t invincible. Blow out soft spots, carve control joints, shred failing sealer, expose aggregate, and you can’t un-do that.

Wood is worse. One bad pass and you’ve raised the grain so aggressively you basically signed yourself up for sanding. Composites can haze or stripe. Stucco can chip. Brick can erode at the mortar lines. Painted surfaces can peel in sheets (which feels satisfying until you realize you just created a prep job).

Look, pressure washing is removal. Sometimes you remove more than dirt.

A DIY-or-hire framework that doesn’t require a spreadsheet

The 60-second safety check

If any of these are true, pause:

– You need a ladder to reach the target area

– There are visible cracks, loose boards, failing mortar, peeling paint

– You’ll be spraying near electrical components or vents

– Runoff will flow into sensitive landscaping or a storm drain you can’t control

The “test patch” rule

Pick an inconspicuous spot.

Try the lowest reasonable pressure with a wide fan tip. If you see fuzzing, etching, striping, or water intrusion, that’s your answer.

The ego check (yes, really)

Ask yourself: *If this goes sideways, am I okay paying to fix it?*

If not, hire it out.

What you’re buying when you hire a pro

Not just “a guy with a washer.”

You’re paying for controlled workflow: pre-wet, chemical selection, dwell time, protection of plants, containment where needed, correct rinse technique, and a final inspection. A good company will also tell you what *not* to wash, which is honestly one of the biggest tells that they know what they’re doing.

And timing? Pros often finish in a fraction of the time because they’re not learning on your property.

Final thought (not a pep talk)

DIY pressure washing is great when the surface is forgiving and the stakes are low. When the surface is fragile, elevated, valuable, or close to electrical and water-sensitive areas, the smartest move is usually to pay for competence.

Clean is nice. Intact is nicer.
