How to Clean Windows Without Streaks: The Complete UK Guide (2026)
There’s nothing quite like the smug feeling of throwing open the curtains on a crisp January 2026 morning and seeing the garden in pin-sharp detail—until the low winter sun swings round and every lazy wipe is lit up like a crime-scene fingerprint. If you’re tired of chasing smears round the pane, this is the last guide you’ll ever need for streak-free windows in 2026, British weather and all.
Before we dive in, I’ll let you into a secret: the enemy isn’t the dirt you can see; it’s the thin film of detergent left behind when you “finish” the job. Get rid of that, and you’ll get streak-free windows every time this year. Below you’ll find the exact window cleaning tools 2026 I keep in my bucket, the vinegar window cleaner 2026 recipe every Nana swears by, plus the squeegee technique 2026 that turned my conservatory glass 2026 from hazy-greenhouse to crystal-clear.
Quick-glance table 2026: what works, what doesn’t
| Method | Streak risk | Cost 2026 | Best for |
|---|---|---|---|
| Kitchen roll + spray polish | High | ££ | Emergency spot-clean |
| Microfibre cloth 2026 + vinegar | Very low | £ | Inside windows, sills |
| Squeegee + warm water | Low | ££ | Large panes, outside |
| Water-fed pole system | Zero* | £££ | Third-storey, hard-water stains 2026 |
*Assumes you rinse final-filtered water; otherwise you’ll still get drip marks.
Step 1 – Pick your 2026 day (yes, it matters)
The best time to clean windows 2026 in the UK is a dry, overcast day with little wind. Direct sun evaporates the water faster than you can wipe, leaving dried-on streaks before you’ve even moved to the next pane. If the 2026 forecast is “sunny spells,” start on the shaded side of the house and follow the shade round.
Step 2 – Assemble the 2026 kit
You don’t need a trolley like the pros, but a few 2026 basics make life easier:
- 10” rubber-bladed squeegee (replace the rubber twice in 2026)
- Microfibre cloth 2026 – at least two, one for washing, one for buffing
- A small stiff brush (old toothbrush) for corners
- Plastic pot scraper for bird bombs and sap
- Bucket of warm water – not hot, or you’ll cook the rubber blade
- White vinegar (5% acidity, the cheap 2026 chip-shop stuff)
- Optional: a drop of washing-up liquid if windows are traffic-film grimy
Step 3 – Mix the 2026 magic potion
Vinegar window cleaner 2026 recipe (makes 1 L)
| 300 ml white vinegar |
| 700 ml tap water |
| ½ teaspoon washing-up liquid (only if greasy) |
Give it a swirl, don’t shake or you’ll be rinsing suds for days. The acid in the vinegar breaks down the alkaline mineral deposits that cause hard-water stains 2026, while the surfactant lets the blade glide.
Step 4 – Inside vs outside windows 2026
Inside vs outside windows 2026 face different enemies. Inside panes collect dust, pollen and cooking film; outside you battle traffic grime, pollen and, if you live near the coast, salt. I tackle inside first so I’m not treadging muddy footprints back in later this year.
Inside 2026:
- Lay an old towel along the sill to catch drips.
- Dip the microfibre cloth 2026, wring until just damp, wipe in a Z-pattern.
- Immediately buff dry with a second cloth, flipping to a clean side when you feel resistance.
Outside 2026:
- Hose off loose dirt first—rubbing grit across glass is how scratches happen.
- Wet the pane with your vinegar window cleaner 2026.
- Scrub with the microfibre or a soft brush on an extendable pole.
- Squeegee from top to bottom, wiping the blade with a cloth after every pass. Angle the handle so water runs toward the uncleaned section (think “skiing downhill”).
Step 5 – The squeegee technique 2026 everyone botches
Keep the blade flat; a 30° tilt channels water into the rubber edge instead of spitting droplets. Overlap each stroke by an inch so you’re not leaving a vertical river. Finish by running the blade across the bottom edge, then wipe the sill with your damp cloth to avoid backsplash.
Step 6 – Dealing with hard-water stains 2026
If you’ve got those cloudy white rings that laugh at glass cleaner, you’ll need an acid hit stronger than table vinegar. Mix 1 part citric acid to 4 parts warm water, sponge on, leave 5 min, agitate, rinse, squeegee. Done. (Citric acid is £2 a box in the 2026 baking aisle—far cheaper than branded “limescale removers.”)
Step 7 – Conservatory glass 2026 & awkward panes
Roof panels love to hold onto drips. Work on a cool 2026 morning, wear rubber-grip gloves, and use a squeegee with an articulated head. Start at the highest point so dirty water doesn’t run over the bit you’ve just cleaned. If you’re on a ladder, follow 2026 HSE rules: three points of contact, and for the love of tea don’t over-reach.
Pros & cons 2026 of DIY vs hiring a local pro
| DIY pros 2026 | DIY cons 2026 |
|---|---|
| Costs pennies after initial kit | Time-consuming if you’ve got 20+ panes |
| Instant gratification on a Saturday | Ladder work is risky above ground-floor |
| You control the chemicals (pets, kids, fishponds) | You’ll still spot the odd smear when the sun hits |
| Pro pros 2026 | Pro cons 2026 |
|---|---|
| Water-fed pole = zero streaks, no ladders | £8–£12 per “standard” window in 2026 prices |
| They’ll do frames, sills and doors too | Need to be in (or give gate code) |
| Insured if they crack a pane | Some firms upsell “special coatings” you may not need |
UK window-cleaning hacks 2026 that save your sanity

- Add a capful of cheap vodka to your vinegar window cleaner 2026; it speeds drying and smells less like a chip shop.
- Cut an old yoga mat into strips to wedge either side of sash windows—catches drips and acts as a squeegee stop.
- In hard-water 2026 areas, finish with a quick spray of distilled water and a fresh blade pass; it’s the poor man’s water-fed pole.

FAQs 2026
1. Can I use tap water in my vinegar window cleaner 2026?
Yes for most of the UK in 2026, but if you live in a hard-water 2026 area (East Anglia, parts of the South-East) swap the final rinse for distilled water to avoid new hard-water stains 2026.
2. How often should I replace the squeegee rubber in 2026?
Every 4–6 months for a homeowner in 2026, sooner if you see nicks or rounded edges. A £2 rubber refill is cheaper than re-washing every pane.
3. Is there a quick way to dry conservatory glass 2026 without ladders?
Use a water-fed pole with a microfibre pad attachment, then switch to the brush head for a final pure-water rinse. Let it air-dry—no squeegee needed.
4. What’s the best time to clean windows 2026 in winter?
Mid-morning (10–11 am) when frost has lifted but before the weak 2026 sun hits the glass. Work in small sections so nothing freezes on the pane.
5. Will vinegar window cleaner 2026 harm window seals or uPVC?
Not at 5% acidity in 2026. Avoid soaking the seals; just wipe, don’t flood. Rinse with plain water if you’re paranoid.
6. Inside or outside— which side do streak-free windows 2026 show smears first?
Usually the inside, because you’re looking through the glass at an angle that catches smears. Always finish the inside last for the ultimate 2026 “ta-da” moment.
