Scrub Smarter: Pans, Ovens, Grout and Everything You Shouldn't Touch
A powder that cleans burnt-on food without wrecking the surface underneath — as long as you know the four exceptions.
Baking soda's second career is as the gentlest useful abrasive in the house. The crystals are hard enough to lift burnt-on food and soft enough that they crumble before they scratch most surfaces. That combination is rarer than it sounds, and it is why the stuff has outlasted a century of cleaning products.
The basic paste
Three parts baking soda to one part water. Thick enough to stay where you put it. Make it fresh each time — it does not keep well and there is no reason to store it.
The technique that does the work
Spread the paste, then leave it. Ten minutes for everyday grime, overnight for burnt disasters. Waiting does more than scrubbing does, and it saves your surfaces and your wrists.
Burnt pans
Cover the burnt base with a centimetre of water, two tablespoons of soda, and simmer for ten minutes. Let it cool. Most of it will lift with a wooden spoon. Repeat rather than attacking it with a metal scourer.
The oven
Take out the shelves. Paste over the glass, floor and sides, avoiding the heating elements and the fan. Leave it overnight. In the morning it scrapes off with a plastic scraper and comes away with the grease. Wipe several times with a damp cloth — soda residue leaves a chalky film and it will smoke on next use if you leave it.
Grout and tiles
Paste, old toothbrush, small circles, leave ten minutes, rinse. This is where an electric toothbrush you were about to throw out becomes the best cleaning tool in the house.
Sinks, hobs and worktops
A sprinkle on a damp cloth for daily marks. Stainless steel: go with the grain, not across it. Rinse properly afterwards or it dries to a white haze.
Baking trays
The brown polymerised layer on an old tray is very stubborn. Soda paste plus a long soak plus patience will improve it. Nothing will make it look new, and that layer is harmless.
Do not use it on
- Aluminium pans — it reacts and leaves them dull and darkened.
- Marble, granite and sealed stone — the abrasive dulls polish and can damage the sealant.
- Glossy or coated surfaces — glass hobs with a printed finish, painted cabinets, screens.
- Non-stick pans — you will take the coating off along with the food.
And never mix it into a container with bleach, ammonia or other cleaning products. Combining cleaning chemicals is one of the genuinely dangerous things people do at home.
Test first, always
Ten seconds on a hidden corner will save you an afternoon of regret. Under the lip of the worktop, the back of the cupboard door, the corner of the tile behind the bin.
