Newspaper for cleaning glass

Does it work?

Established practitioner practice

The scope is narrow. An approval body specifies newspaper for one job on one kind of glass, which is good evidence about that job and says nothing about windows.

This is a verdict on whether the technique is effective. Whether it is safe on a particular surface is a separate question, answered below.

Where not to use it

The proposed mechanism

The explanation below is what is offered for this technique. No evidence establishes that this is what actually happens, so treat it as a plausible story rather than as a finding.

Three mechanisms are proposed and they are not equally supported. The first is textural: paper has no loose fibres to shed, unlike a woven cloth, so nothing is left behind — this is plausible and is the likeliest explanation of whatever effect exists. The second is absorbency, which is unremarkable and true of many materials. The third, that printing ink acts as a mild polishing agent, is the one usually offered as the special ingredient and the one with no evidence behind it at all; it also depends on an ink formulation that has changed. What the appliance guidance actually relies on newspaper for is different again: it is a disposable carrier for ash that can be discarded with the soot on it, and its value there is practical rather than chemical.

Background

Crumpled newspaper instead of a cloth is among the most durable domestic cleaning traditions, usually justified by some combination of the paper's lint-free surface, its absorbency, and the printing ink acting as a mild polish. No authoritative source assesses it for windows. HETAS, the UK solid-fuel appliance approval body, specifies scrunched-up newspaper as the carrier for the ash technique on stove glass, and describes it as an old technique used for many years — which is real evidence that newspaper is a suitable applicator on glass, and is not evidence about streak-free window cleaning. Two things have also changed underneath the tradition: modern newsprint inks and paper stock are not the ones the practice grew up with, and no source establishes whether the property being relied on still holds.

Conditions

• On stove glass, as the carrier for the ash technique, with the glass cool
• Not on painted, printed or coated surfaces adjacent to the glass

What it does not do

• The one authoritative source is about stove glass, not windows, and it does not extend to windows
• Newsprint inks and paper stock have changed since the practice became established, and no source confirms the property still holds
• Wet newsprint transfers ink to porous surrounds, painted frames and hands

What to use instead

• Microfibre cloth — Split synthetic fibres with a very large surface area, which lift and trap soil mechanically — often with water alone.
• Detergent — A surfactant-based cleaner. The general-purpose answer for greasy and particulate soil, and the correct first choice far more often than any specialist product.
• Rinsing and drying — The step people skip, and the one that decides whether cleaning protected the surface or damaged it. Residue left behind is exposure that continues after you stop.
