Why You Should Only Clean Your Glasses with a Microfibre Cloth
Microfibres are spun so finely that they absorb grease and dust rather than pushing it across the lens – unlike clothing, paper or tissues, whose coarser fibres and additives can cause micro-scratches.
What makes microfibre technically different
Microfibres are extremely finely spun fibres (significantly finer than a human hair) that, thanks to their large surface area, genuinely absorb grease and dust particles and trap them within the fibre structure, rather than just spreading them across the surface.
Why clothing and paper are the worse choice
T-shirts, jumpers or paper tissues contain coarser fibres (plus wood fibres, in the case of paper) that push embedded dust and sweat-salt particles across the lens while wiping, rather than absorbing them – the mechanism behind most micro-scratches (see Home remedy myths and Anti-reflective coating).
The limit: even a microfibre cloth can cause damage
A microfibre cloth is only as good as its own cleanliness – an already dirty cloth acts like sandpaper itself. Find out how to properly look after your cloth in the article How to clean a microfibre cloth correctly
