Squishmas Dumpling Advent Calendar

It is machine washable and built to be washed and used again hundreds of times. Wash it with your normal load, no fabric softener — softener coats the fibres and is the one thing that will stop it working. Line dry or tumble on low.

This is the bit that makes it different from a normal cloth. The fibres are split into strands far finer than a human hair, and they carry a slight static charge, so dirt and grease are lifted off the surface and trapped inside the cloth. A cotton cloth or a paper towel does the opposite — it pushes the dirt around and leaves a film behind, which is why you need a spray to make it work. Wet it, wring it out hard, wipe.

No. That is the point of it. Water is what activates the fibres. If you want to use a cleaner on something particularly greasy you still can, but for day-to-day cleaning you will not need one — which is another £30 or £40 a year you stop spending.

Glass, mirrors, windows, shower screens, stainless steel, granite, marble, worktops, hobs, tiles, chrome, TV and laptop screens, car interiors and windscreens. It is safe on delicate surfaces and will not scratch — the fibres are soft and there is no abrasive in them.

No — that is the whole point of it, and it is what the guarantee covers. The one thing to get right is wringing it out: streaks come from too much water, so wring it until it is barely damp before you wipe. On very dirty glass, go over it once damp and once dry.

Yes — for wiping, spills and surfaces, which is nearly everything a roll gets used for. One pack of five XXL cloths does the work of around 75 rolls. Wipe, rinse or wash it, use it again. Nothing to reorder and nothing going in the bin.

One pack of five covers a single cleaning station — a stack by the kitchen sink, say. Most homes end up wanting one stack per room: kitchen and stainless steel, bathroom and mirrors, glass and windows, and the car. That is why the 15-pack is the one most people order, and why it works out about a third cheaper per cloth.

Machine wash up to 60°C with your normal detergent. No fabric softener and no bleach. They come out of the wash ready to use again — there is nothing to replace and nothing to reorder.
