White vinegar and baking soda are cheap, they work well on many everyday messes, and you probably already own both. Here's where each one shines - and, just as important, where to leave them in the cupboard.

The basics: vinegar is acidic, so it dissolves limescale, soap scum and mineral deposits. Baking soda is a mild abrasive and deodorizer, good for scrubbing and neutralizing smells. Mixing them makes an impressive fizz, but they mostly cancel each other out - use them separately for best results.

1. Descale the kettle

Fill halfway with equal parts vinegar and water, bring to a boil, let it sit for an hour, then rinse well and boil fresh water once.

2. Clean the shower head

Fill a plastic bag with vinegar, tie it around the shower head with a rubber band so the nozzles are submerged, and leave it for an hour. Run the hot water to flush.

3. Shine glass and mirrors

One part vinegar to one part water in a spray bottle, wiped off with a microfiber cloth, gives streak-free glass.

Glass spray bottles

Reusable bottles for your own vinegar-water mix - label them clearly.

4. Steam-clean the microwave

Microwave a bowl of water with a splash of vinegar or a few lemon slices for three minutes. Leave the door closed for five more, then wipe - the grime comes right off.

5. Freshen the dishwasher

Put a cup of vinegar upright on the top rack and run an empty hot cycle. Clean the filter first; that's where most smells come from.

6. Scrub the sink

Sprinkle baking soda, scrub with a damp sponge, rinse. Works on stainless steel and ceramic.

7. Deodorize the fridge

An open box or a small bowl of baking soda on a shelf absorbs smells. Replace every three months.

8. Lift oven grease

Make a paste of baking soda and water, spread it on the inside of a cold oven (avoid the heating elements), leave overnight, then wipe and scrape. Spray a little vinegar on any white residue and wipe again.

Non-scratch scrub sponges

Scrubs off baking soda paste without scratching the oven or sink.

9. Refresh carpets and mattresses

Sprinkle baking soda, leave for 30 minutes (or a few hours for a mattress), then vacuum thoroughly.

10. Clean the washing machine

Run an empty hot cycle with a cup of vinegar to help with limescale and odor, and wipe the rubber door seal - mold loves it.

11. Grout paste

Baking soda with a little water, scrubbed in with an old toothbrush or a grout brush, brightens dingy grout lines.

Stiff, narrow bristles get into grout lines a sponge can't reach.

Where NOT to use vinegar

Never mix these

Always keep homemade cleaners in clearly labeled bottles, and keep them out of reach of children and pets.

These hacks are most useful as part of a monthly deep clean - descale the kettle and shower head, clean the dishwasher filter, wash the machine. The full monthly and seasonal list is in the Home Reset Planner.
