What are Universal Cloths made from?

Both Universal Cloths and Glass Cloths are made from the same 84% polyester and 16% polyamide microfibre blend. The polyester gives the cloth structure and durability so it holds shape through thousands of washes. The polyamide gives the fibres their grip and absorbency so they trap dirt and water rather than push it around. The split-fibre weave creates tiny hooks that physically grab grime, which is why microfibre cleans well with just water on most surfaces.

What's the GSM difference between Universal Cloths and Glass Cloths?

Universal Cloths are 420 GSM, thicker and plusher with more fibres per square metre for more absorbency and scrubbing surface. They suit benches, tiles, sinks, taps, and stovetops. Glass Cloths are 300 GSM, slightly lighter with a tighter weave that glides over smooth surfaces without streaks or lint, for windows, mirrors, glass shower screens, and chrome.
