Cleaning

Almost everything in a home comes clean with water and a good cloth. Whatever you add to that water stays behind as it dries, and that film is exactly what you see again a week later as fresh dirt.

Where to start

Choose by task, not by product. Every room has its own kind of dirt: grease in the kitchen, limescale in the bathroom, dust and grit on the floor. That's why this is sorted by job rather than by product type.

What a cloth won't fix

Years of limescale, baked-on grease and toilet deposits are a job for a product, not a cloth. A cloth keeps clean what is clean. For more on that, see the difference between soda crystals and bicarbonate of soda, including what you should never mix.
