A clean window isn't about the product or the effort. It's about technique. You can wipe the frame three times, use an expensive professional spray, and still end up with streaks, glare, and bands — especially when the sun is setting straight into the glass. Or you can take plain water, the right cloth, and a cheap squeegee — and the window will shine. The secret is in sequence, in the squeegee angle, and in the time of day. In Tashkent, where dust settles on glass faster than in many cities and where spring and autumn bring sharp temperature swings, correct technique is the difference between "I spent half a day for nothing" and "the window is invisible". Below are eight techniques our 166 Cleaning crew uses.
1. Time of day: never in the sun
This is rule number one, and the most commonly broken. In sunny weather the cleaning fluid dries on the glass in seconds — faster than you can distribute and remove it. The result is the classic streaks that no microfiber or newspaper will fix. You end up rewashing and the cycle repeats.
Optimal timing in Tashkent: early morning before 9:00, evening after 18:00, or a cloudy day. In winter — any daylight hour, the sun isn't aggressive. In summer — best to reschedule to a cool evening.
If there's no choice, break the window into 40–50 cm sections and work them one at a time.
Foreman's rule: dry glass in the sun is enemy number one. Half of Tashkent's windows get washed on hot days and then the owner wonders why there are streaks. Move to evening — twice as fast and three times cleaner.
2. The right tools
- Squeegee with a rubber blade. The main tool. No cloth, however expensive, matches the result of a rubber edge pulling water in one pass.
- Microfiber wash sleeve. Soft, holds water, spreads evenly.
- Dense microfiber cloth. For frames, sills, and corners the squeegee can't reach.
A 25 cm squeegee covers 90% of residential windows. Panoramic balconies need 35 cm or more. Paper towels leave lint, newspaper is an outdated myth, ordinary cotton rags don't work.
3. Solution: water, vinegar, a couple of dish-soap drops
- 1 litre of warm water.
- 2 tablespoons of 9% vinegar.
- 1–2 drops of dish soap.
This solution breaks down street dust, rain marks, and greasy fingerprints. Leaves no film, safe for all glass including tinted. Ammonia works too (1 tbsp per litre), but open the window and keep kids and allergic people away. For families with asthma we recommend the vinegar mix — the smell only exists during application and disappears when dry.
4. Squeegee technique: horizontal, then vertical
- Wet the entire glass with a saturated wash sleeve. Don't save on fluid.
- Give it 15–30 seconds to soften dirt.
- Start at the top-left corner with a short horizontal stroke along the upper edge.
- Then pull the squeegee straight vertically, top to bottom, in one movement without lifting.
- Wipe the squeegee blade with a dry microfiber after every pass — critical.
- Overlap each new pass by 2–3 cm.
- Finish with a horizontal stroke along the bottom to collect the water line.
After this there should be no visible drops. Wipe frame and sill separately with dry microfiber.
5. Stubborn stains
Rain marks with limescale
After Tashkent's dusty rains there are whitish streaks — mineral sediment from hard water. Mix 1 tbsp citric acid in a glass of warm water, apply to the streak, wait 1–2 minutes, rinse with the main solution.
Tape residue and stickers
Glue doesn't come off with water. Soak the spot with warm vegetable oil or WD-40, wait 2–3 minutes, peel off with a plastic card. Then wash the window with the main solution twice.
Old insect marks
Cotton pad soaked in vinegar solution, placed on the spot for 3–5 minutes, then removed. Never scrub dry — scratches.
6. Seasonal moment: spring windows after winter
March–April in Tashkent is the strongest window season. All winter residue has settled: heating dust, condensation, poplar sap, outdoor splashes. Spring washing is almost always a double procedure:
- First pass. Saturated solution (1.5× vinegar).
- Rinse. Regular solution to remove the first-pass residue.
- Final pass. Clean warm water with a drop of soap for perfect clarity.
For ground-floor apartments or those facing dusty streets, do this three-step wash twice a year. For balconies or panoramic windows, consider ordering a deep cleaning that includes window washing — the crew arrives with ladders and professional gear.
7. Mistakes that leave streaks
- Too much dish soap in the solution. Foam dries white. One drop per litre max.
- Dry sleeve or dry squeegee. Dry tools leave bands.
- Not wiping the blade between passes. The main cause of streaks.
- Working against the sun. Even winter noon sun can dry too fast.
- Using a cloth on a big window. Cloth technique fails past 60 cm width.
- Cheap short-pile microfiber. Smears instead of extracting.
- Washing in freezing temperatures. Below +5 °C the solution freezes on the glass.
8. Frames and sills
Plastic frames
Main enemy: dust in corners and around rubber seals. Same solution, damp microfiber. Heavy yellowing — baking soda paste with a soft brush. No abrasives — they scratch.
Seal rubber
Often forgotten. Wipe damp, once per season apply silicone grease to extend life 2–3×.
Sill
Usually the dirtiest part. Remove pots, wash with solution and dish soap, treat water rings with baking soda. Before returning pots, add cork or silicone pads — otherwise rings return in a week.
When to call the crew
- Panoramic glazing in penthouses.
- Windows with no outside access from a balcony.
- Post-renovation windows with paint, cement, foam residue.
- Cottages with second and third floor windows.
- Offices, shops, storefronts.
In these cases the crew arrives with telescopic squeegees, ladders or rope access. Consider combining with upholstery and curtain cleaning in one visit.
FAQ
Can I use newspaper like in old days?
It used to work because of specific ink chemistry. Modern ink doesn't help, plus it stains hands. Works, but microfiber is much better.
How often should windows be cleaned?
In Tashkent, 2–4 times a year: spring (after winter and poplar), summer (after dust), autumn (before heating), winter optional.
Window is clean but streaks return the next day — why?
Almost always outside residue — rain or dust. Wash both sides.
Is ammonia safe?
Yes, with care: open window, no kids or allergic people. Smell disappears once dry.
Why do PVC frames turn yellow?
UV and reactions with smoke or grease. Baking soda paste works early; severe yellowing needs special whiteners or bead replacement.
Window cleanliness as a marker for the whole apartment
Few people notice consciously, but visitors use window cleanliness to form an impression about the whole home. Dirty glass creates a "nothing has been done here in a while" feeling even when the interior is perfectly clean. Conversely, sparkling transparent windows lift the perceived quality of the entire interior by several notches. That's why experienced realtors in Tashkent insist on washing windows before a sale or rental — on their own they don't make the apartment better, but they substantially shift subjective assessment.
Another practical upside of regular washing — more daylight. Rooms with dirty glass receive 20–30% less natural light than they could. That directly affects both mood and electricity bills, because artificial lighting turns on earlier. Clean windows work as a passive free source of daylight comfort.
Windows are the most "visible" part of cleaning. Once done, the apartment looks brighter, wider, cleaner. Doing it correctly is a skill you build in 5–10 attempts. If you don't want to spend half a day experimenting or your windows are oversized, call 1331 — the 166 Cleaning crew will come at a convenient time with all the gear. We'll do it perfectly, inside and out. The call is free from any Uzbekistan operator, we work 24/7.
