Which Universal Cloth should I use?Updated 7 hours ago
TL;DR: The difference is weight and colour. Glass Cloths 3pk are 300GSM, a lighter weave that buffs windows and mirrors to a streak-free finish, with no scrubby corner to catch on a pane. Universal Cloths 3pk are a denser 420GSM for general and bathroom cleaning, with a non-scratch scrubby corner for stuck-on spots. Both are the same 84% polyester, 16% polyamide microfibre. Universal Cloths Mixed 4pk covers the whole home in one colour-coded set, and the code is green for general cleaning, blue for bathrooms, white for windows.
Which Universal Cloth should I use?
✓ Glass, mirrors and windows
Glass Cloths 3pk are the lighter 300GSM weave, built to buff glass to a streak-free shine rather than scrub it. There is no scrubby corner to catch on a pane. White is the window colour in the Koh code.
✓ Everyday surfaces
Universal Cloths 3pk are the denser 420GSM weave for general and bathroom cleaning, each with a non-scratch scrubby corner for stuck-on spots. Use them dry for dusting, or damp with water or a small amount of cleaning solution for a deeper clean.
✓ The whole home in one set
Universal Cloths Mixed 4pk includes general, bathroom and window cloths together, so you have the right cloth for each room without deciding up front. The general and bathroom cloths are 420GSM and the window cloth is the lighter 300GSM weave.
What is the difference between Glass Cloths and Universal Cloths?
✓ Weight tells them apart
✓ What the colours mean
The colours are a system, not decoration. Keeping a cloth to its own colour is what stops a cloth that has been over bathroom surfaces ending up on a mirror.
✓ Why the scrubby corner matters
The non-scratch scrubby corner on the Universal Cloths is there for stuck-on spots on worktops and surfaces. On glass you want an uninterrupted face to buff with, which is why the Glass Cloths are kept plain and lighter at 300GSM.
What are the cloths made of and how long do they last?
✓ What they are made of
✓ Up to 3,000 washes
The cloths are made to last up to 3,000 washes, so a pack is meant to be washed and reused rather than replaced. The microfibre lifts dirt and grime without leaving streaks, and washing it correctly is what keeps it doing that.
How do I keep my cloths working?
✓ How to wash them
There is a full guide on how to wash the Universal Cloths, and another on how to use them.
✓ If they are leaving streaks
Make sure the cloth is fully dry before you start. If it has absorbed too much water along the way, swap it out and finish the job with a dry cloth. This is the usual cause of streaks on glass and mirrors.
✓ Keep colours to their zone
Green is for general cleaning, blue is for bathrooms and white is for windows. Stick to the code and a cloth that has been over bathroom surfaces never ends up on a mirror or a worktop. You can also buy cloths separately to top up just the pack you get through.
