Surprising Uses for Olive Oil Around the House
Olive oil earns its place in the kitchen, but the bottle is quietly useful all over the house. Here are the ones that actually work — and the single rule that saves you from wasting your good oil.
None of these are new; they are the everyday tricks of people who grew up with a tin of oil by the stove and no cupboard full of single-purpose sprays. Olive oil is a fat and a mild antioxidant, which is exactly why it conditions, protects and lifts grime — the same chemistry that makes it good on your plate makes it useful on a hinge or a chopping board.
| Job | How | Why it works |
|---|---|---|
| Polish stainless steel | A few drops on a cloth, buffed with the grain | The oil fills fine scratches and repels water spots |
| Feed wood & leather | A thin coat, wiped on and buffed off | Fat replaces what dry timber and hide have lost |
| Free a squeak | One drop on a stiff hinge or zip | A light lubricant that won’t gum up like some sprays |
| Lift sticky residue | Rub in, leave a minute, wipe away | Oil dissolves the tar, sap or label glue |
| Season cast iron | Thin film, heated after washing | Builds the non-stick patina and blocks rust |
| Moisturise skin & hair | A little, warmed in the hands | A simple emollient — use sparingly, it’s rich |
Around the house
The house jobs all lean on the same trick: a very thin film of oil, buffed until it no longer feels greasy. On stainless steel it leaves a streak-free shine and fends off fingerprints. On dry wood and leather — boards, salad bowls, a tired belt — a thin coat feeds and revives. A single drop frees a squeaking hinge or a stubborn zip. And oil is a patient solvent: rub it into sticky label glue, tree sap or tar and it lets go without scratching.
On you
People have rubbed olive oil into skin and hair for as long as they have pressed it. As a plain moisturiser for dry hands, elbows and feet it is cheap and effective; it conditions hair and scalp; and a little on a cotton pad lifts makeup gently. The honest caveats: it is rich, so use a small amount; it can aggravate acne-prone or very oily skin; and it is a moisturiser, not a medicine — no bottle of olive oil cures a skin condition. This is general information, not medical advice.
The kitchen jobs that count
Beyond cleaning, the bottle earns its keep at the stove in ways worth naming: greasing a tin so a cake turns out clean, loosening pasta so it doesn’t clump, softening dried-out brown sugar, or making a quick emulsion for a dressing. These aren’t tricks so much as the ordinary competence of a kitchen that keeps olive oil within arm’s reach — which, once you do, you never go back from.
Use the cheap oil for the house, never your good bottle. A plain olive oil — even one slightly past its best for the table — polishes and conditions just as well as the finest estate extra virgin. Save the peppery, high-polyphenol extra virgin for your plate, where the flavour and the antioxidants actually matter. Rubbing a €30 oil into a door hinge is money quite literally down the drain.
Getting it right
- Keep a cheap bottle aside for household jobs; hoard the good one for eating.
- Always finish with a thin, buffed film — too much oil goes sticky and attracts dust.
- On skin, use sparingly and stop if it doesn’t suit you.
- Don’t oil unsealed stone (marble, granite worktops) — it can stain.
Household olive oil: common questions
Can I use good extra virgin oil for cleaning?
You can, but it’s a waste. A cheap plain olive oil polishes and conditions just as well — save the peppery extra virgin for the plate.
Does olive oil really polish stainless steel?
Yes — a few drops buffed with the grain leave a streak-free shine and help repel water spots and fingerprints.
Is olive oil good for skin and hair?
As a simple moisturiser and conditioner, yes, used sparingly. It suits dry skin better than oily or acne-prone skin, and it’s a cosmetic, not a cure.
Can I season cast iron with olive oil?
Yes — a thin film heated after washing helps build the non-stick patina and keeps rust off, though some cooks prefer a higher-smoke-point oil for the initial seasoning.
Where should I not use olive oil?
Avoid unsealed stone like marble, and don’t leave a thick layer anywhere — too much oil turns sticky and collects dust rather than protecting.
The whole thing comes down to one habit: keep two bottles. A cheap one lives with the cleaning things for hinges, boards and steel; the good one lives by the stove for eating. People who grew up around oil never confused the two, and they never bought a cupboard of single-use sprays either. The house tricks are real and they work — just don’t pour your best peppery extra virgin onto a squeaky door. That oil’s polyphenols are wasted on a hinge and precious on your plate.
