TL;DR
The newspaper trick worked because of the paper and the ink of an earlier era, not because of anything magic about newsprint. Paper stock and printing inks changed, and modern newspaper is softer, more absorbent in the wrong way, and more likely to smear ink onto a frame. A lint-free microfiber cloth or a squeegee outperforms it and does not stain your hands.
What the trick relied on
Older newsprint was a denser, harder sheet, and it was printed with oil-based inks that dried into a firm film. Wadded up, that sheet acted like a very fine polishing pad: rigid enough to burnish glass, absorbent enough to take up moisture, and lint free because the fibers were tightly bound.
The result was a genuinely good finish. People were not imagining it.
Two things then changed. Paper stock moved toward lighter, softer, more recycled sheets that break down when wet. And many printers shifted toward soy-based and water-based inks, which behave differently when they get damp and are much more willing to transfer onto whatever the paper touches.
So the technique did not stop working because glass changed. It stopped working because its tool changed underneath it.
What actually causes streaks on glass
Streaks are almost never a cloth problem in isolation. Four causes account for nearly all of them.
Too much cleaner. Excess product cannot evaporate cleanly and dries as a film. This is the same over-dosing failure described in does more soap clean better, and it is the single most common cause.
Working in direct sun. A hot pane flash-dries the solution before you can wipe it, leaving the residue exactly where it landed.
A contaminated cloth. Fabric softener coats microfiber and destroys its ability to absorb, and a cloth that has picked up polish or wax redeposits it.
Residue from a previous product. Old spray-and-wipe films build up on glass, so the first proper clean often needs a stripping pass with plain water and a small amount of detergent.
Getting those four right matters more than which cloth is in your hand.
The method that actually works
Two approaches produce a genuinely clear pane. Pick one and do it properly.
Two-cloth microfiber method. Spray lightly with a glass cleaner or a very dilute detergent solution. Wipe with one damp microfiber cloth to remove soil. Immediately follow with a second, completely dry, lint-free cloth, buffing until the glass squeaks. The dry cloth is doing the work that a wadded newspaper used to do.
Squeegee method, which is what professionals use on anything larger than a small pane. Wet the glass with a very dilute detergent solution using a sponge or a scrubber. Pull the squeegee from top to bottom in overlapping strokes, wiping the blade with a lint-free cloth after every stroke. Detail the edges with a dry cloth.
Either way, the technique rules are the same. Work in the shade or on an overcast day. Use less solution than feels right. Do the inside strokes horizontally and the outside strokes vertically so you can tell which side a remaining streak is on. And wash the frames and sills first, because grit carried from a sill onto the glass scratches it.
Glass and mirror care without streaks covers the full sequence including screens, tracks, and mirrors.
What to use instead of newspaper
A flat-weave microfiber cloth marked for glass is the most reliable option, because it has less nap than a general-purpose cloth and leaves nothing behind. Wash microfiber separately from cotton, in warm water, with no fabric softener and no dryer sheet, and it will keep working for years.
Other workable options include a clean lint-free cotton huck towel, a chamois for a final buff, and a coffee filter for small panes and mirrors in a pinch. Paper towels are the common fallback and the least good one, since most shed fibers as soon as they get wet.
Whatever the cloth, the actual removal is done by the wet pass and the wipe, not by scrubbing harder. That relationship between agitation and removal is the point of rinsing vs scrubbing, and glass is where it shows up most obviously, since pressing harder on a pane just spreads residue thinner.
Two cautions worth stating
Avoid ammonia-based cleaners on coated glass, on tinted windows, and on any display panel. Ammonia and alcohol damage the coatings on screens, and many low-emissivity and tinted window films carry their own manufacturer restrictions. Check the window manufacturer's guidance before using anything but plain water and a mild detergent on a coated or filmed pane.
And never combine a glass cleaner with chlorine bleach. Many glass products contain ammonia, and bleach with ammonia releases chloramine gas. Use one product, rinse, and ventilate. Source: U.S. Centers for Disease Control and Prevention
The newspaper trick belongs in the same category as several other pieces of inherited cleaning folklore: real once, obsolete now, and repeated long after the conditions that made it true disappeared. Cleaning myths worth unlearning collects the rest, and the equipment shortlist most professional house cleaning services carry for glass is short for exactly this reason.
FAQ
Does cleaning windows with newspaper still work?
Not well. The trick depended on denser paper stock and oil-based inks that no longer dominate printing. Modern newsprint is softer, breaks down when wet, and is likelier to transfer ink onto frames and hands. A lint-free microfiber cloth works better.
Why did newspaper work on glass originally?
Older newsprint was a firmer sheet with tightly bound fibers and oil-based ink that dried into a hard film. Wadded up it behaved like a fine polishing pad: rigid, absorbent, and lint free. Paper and ink formulations have since changed.
What causes streaks on windows?
Usually too much cleaner, working in direct sunlight, a cloth contaminated by fabric softener or polish, or residue left by a previous product. Fixing those four matters far more than which cloth you use.
What is the best cloth for cleaning glass?
A flat-weave microfiber cloth marked for glass, because it has less nap than a general-purpose cloth and leaves no fibers. Wash microfiber separately, warm, with no fabric softener or dryer sheets, and it stays effective for years.
Should I use a squeegee on home windows?
For anything larger than a small pane, yes. Wet the glass with a very dilute detergent solution, pull the squeegee top to bottom in overlapping strokes, and wipe the blade after every stroke. Detail the edges with a dry cloth.
Can I use an ammonia glass cleaner on tinted windows?
Check the manufacturer's guidance first, because ammonia damages many window films and coated glass, and it should never touch a coated display panel. Plain water with a mild detergent is the safe default on anything filmed or coated.
Every home is different, and window work depends on the glazing, the access, and how many panes there are. If you would rather not do it yourself, get a quote and we will walk you through it.
