Mirrors promise clarity and give you smears. You wipe harder, they fog, the light shifts, and you spot another streak grinning back at you. The fix might already be next to your sink.
Early light slid through the blind and landed on a constellation of streaks that hadn’t been there last night, or maybe I just hadn’t noticed. I cupped warm water in my hands, tried a quick swipe with the corner of a T-shirt, and watched the haze bloom across the glass like a low cloud over the moors.
I’ve stood in front of fancier sprays with sharp citrus labels and promises of shine, only to leave fingerprints of regret and a wobbly glare line where the towel stopped. The worst bit is the tilt of your head, the squint, the little breath on the glass, as if the mirror might meet you halfway. It never does. *There’s a simpler way, and it’s almost too ordinary to believe.*
A single spoonful, oddly enough.
Why mirrors streak in the first place
Streaks are tiny stories left behind: dried droplets, soap scum, leftover product, even minerals in tap water. When you rub at them without the right mix, you spread the residue into tidy lines that look sleek under soft light and awful in daylight. The mirror isn’t the villain; the film is.
At a friend’s flat in Manchester, we tried three methods on the same hall mirror before a dinner. Spray-and-wipe left a faint zigzag in the corner. Vinegar and newspaper made the glass sharp, but the ink smudged the frame. A bowl with a dash of washing-up liquid and warm water? The streaks lifted, and the glare line vanished when the sun finally swung round.
There’s logic hiding in that bowl. Washing-up liquid contains surfactants that cut through grease and beauty residue, then help the water slide off evenly rather than bead and dry patchy. Warm water loosens the grime and dissolves the soap just enough to spread thin and clean. Paper towels shed lint; microfibre doesn’t. That’s the whole puzzle.
The spoonful method, step by step
Fill a mixing bowl with warm tap water and add **one spoonful of washing-up liquid**. Dip a clean microfibre cloth, wring it until it’s damp-not-dripping, and wipe the mirror in slow, overlapping S-shapes. Follow with a second, dry microfibre cloth to buff until the glass hums with clarity.
Keep the water **warm, not hot water**, so it doesn’t flash-dry on the glass. Rinse and wring the cloth again if the mirror is very grubby, rather than pushing dirt around. If there’s toothpaste on the edge or hair spray fog, do a gentle pre-wipe in that spot, then return to your smooth strokes.
We’ve all had that moment where you clean in a rush, step away proud, then spot a ghostly swipe at 4 p.m. Mini heart-sink. Let’s be honest: nobody actually does this every day.
“Glass isn’t about shine, it’s about removing the film. Surfactants do the heavy lifting; the dry cloth does the show.” — a professional cleaner who’s seen every bathroom under the British sun
- Go **microfibre over paper towels** to avoid lint and static streaks.
- Change the buffing cloth if it feels damp; dry fibres polish better.
- Edge first, centre second: frames hide grime that smears inwards.
- If you’re battling hard-water marks, finish with a final pass of distilled water.
- For tall mirrors, clean top-down so drips don’t rewrite your work.
The small ritual that changes the whole room
A mirror without streaks changes more than the mirror. Your bathroom feels calmer, your hallway brighter, your face a touch kinder in the morning light. The method takes three minutes, costs pennies, and slots into real life without a new gadget or a plastic bottle headed for the bin.
What surprised me wasn’t the shine but the consistency. The next day, the mirror stayed clear through steam, splashes, and a scramble for the late train. Give it a try once and you start seeing other small places where warm water and a spoonful do the trick: the glass table, the hob splashback, a wardrobe door that had a dull film for years.
It’s not magic. It’s less friction in your day, and a little proof that simple things still work when the labels shout too loudly.

FAQ :
- How much washing-up liquid should I use?About one teaspoon per bowl of warm water. You want slip, not suds.
- Will this leave a film on my mirror?Not if you wring the cloth well and buff dry with a second cloth. Any trace vanishes in the polish.
- Can I use cold water instead?You can, but warm water helps dissolve residue and spreads more evenly on glass.
- Is it safe on antique or tinted mirrors?Yes for gentle cleaning, avoiding wood frames. Test a corner if the silvering looks fragile.
- What if I only have paper towels?They’ll work in a pinch, though they shed lint. Fold thick, go light on pressure, and finish with a dry pass.
