Cleaning is mostly a matter of matching the right chemistry to the right mess. Get that right and most jobs stop needing effort. Get it wrong and you either waste an afternoon or damage the thing you were cleaning.
The whole of it, in one idea
Almost every domestic cleaning problem is one of three types, and each has an opposite.
- Mineral deposits, meaning limescale, hard-water marks and soap scum. These need
acid. Vinegar is the cheap one; a proper descaler is the strong one.
- Grease and organic soil, meaning cooking fat, body oils, food residue. These need
alkali. Washing-up liquid, bicarbonate of soda, or a dedicated degreaser.
- Germs, which is a different problem from dirt. These need a disinfectant, used for
the contact time on the label.
Most of the time people reach for whatever is under the sink and scrub harder. Working out which of the three you have turns the job into a short one.
Where the damage happens
- Acid on stone. Marble, limestone and many composite worktops etch permanently. This is
the single most expensive cleaning mistake in a modern kitchen.
- Abrasives on anything polished, lacquered or coated. It comes off and does not go back.
- Alkali on wool and silk, which are protein fibres and are damaged by it.
- Mixing products, which is a safety issue rather than a damage one. The full do-not-mix
list is on household chemicals.
Things worth doing in the right order
- Dry first, wet second. Vacuum or brush loose debris before anything wet touches it, or
you turn dust into mud and grind it in.
- Top down. Everything you dislodge falls, so clean the shelf before the floor.
- Let the product work. Nearly every cleaner is designed to sit for a few minutes. That
dwell time replaces the scrubbing, and skipping it is why people think a product is weak.
- Rinse. Residue attracts dirt, so a surface that was not rinsed gets dirty faster than
one that was never cleaned.
What we will not tell you
We do not publish reviews of products we have not tested. Where we compare cleaning products it is on published ingredients, pack size and cost per use, with the date we checked it. If a site tells you it tested fourteen oven cleaners, it is worth asking how.
