Oven cleaning with coins: a simple product-free trick

An unexpected method is doing the rounds, promising quick, safe and affordable cleaning for everyone.

Rather than spraying harsh cleaners or using homemade mixtures, a straightforward idea is gaining popularity. It relies on items most people already have at home and uses precise mechanical action to lift baked-on grime without damaging the appliance.

Why change your habits?

Concentrated household cleaners can sometimes leave behind residues. These remnants may smoke the next time you cook. They can linger in the air and affect the flavour of food. Costs also rise quickly if you clean frequently. Powder- or acid-based recipes take time and require thorough rinsing. Many people are therefore looking for a simpler, faster and more restrained approach.

“A clean oven heats more evenly, reduces burnt smells, and lowers the risks associated with greasy deposits.”

The coin cleaning trick

Users are sharing a surprising technique: rubbing encrusted areas with low-value coins. The method uses neither bicarbonate of soda nor vinegar. Instead, it relies on gentle abrasion, controlled by hand, to loosen the carbonised layer.

What you need

• 2 to 3 1p, 2p or 5p coins
• Warm soapy water, with a few drops of washing-up liquid
• A non-abrasive sponge and a microfibre cloth
• Household gloves for a secure grip

The steps

• Switch off the appliance at the mains and allow it to cool completely.
• Remove the oven shelves and roasting tray. Soak them in hot soapy water for 20 to 30 minutes.
• Dampen the dirty areas inside the oven. Dab them with the sponge to soften the layer.
• Hold the coin flat against the surface. Rub using short movements without pressing hard. Focus on black marks and hardened edges.
• Immediately wipe away the loosened residue with the sponge. Rinse, then repeat if needed.
• Finish by wiping with clean water. Dry with the microfibre cloth to prevent streaks.

“Always place the coin flat against the oven surface. Avoid its edge, which is more abrasive and more likely to leave marks.”

Why it works

Small copper-plated steel coins provide even micro-abrasion. Copper moves smoothly over hard enamel and does not clog easily. Moisture softens polymerised grease and helps to minimise scratches. Your hand can adjust the pressure moment by moment. You work only on the dirty area and stop as soon as the deposit lifts. The action remains localised and precise, with no foam or steam.

Oven materials and limitations

Not every oven surface tolerates this method equally well. Vitreous enamel can withstand gentle abrasion. Brushed stainless steel can mark more readily when rubbed against the grain. Toughened glass in the door may scratch when an object is too hard, particularly around printed markings. Catalytic liners have a microporous coating. Rubbing them with metal can smooth this surface and reduce its effectiveness.

• Standard internal enamel: testing is possible, gently, on an inconspicuous area.
• Catalytic liners: choose a damp cloth and frequent wiping instead, without metal.
• Oven door glass: use a glass scraper designed for the purpose, held at 30° and kept lubricated at all times.
• Door seals: do not rub them. Clean with a cloth and soapy water, then dry.

“Test the method first behind a shelf or in a lower corner. Check that it leaves no mark before treating a larger area.”

Precautions and safety

• Disconnect the oven before doing any cleaning.
• Wait until it has cooled fully to avoid thermal shock.
• Keep away from printed areas and seals. Do not scrape temperature sensors.
• Always work on a dampened surface. Lubrication reduces friction and helps grime come away.
• Replace the sponge as you go. A saturated sponge spreads grease around.
• Rinse carefully so that no soapy residue remains.

Save time after every use

Take action immediately after messy cooking. Once the appliance is warm rather than hot, wipe it with a damp cloth. Fresh splashes come off in seconds. Place a reusable oven liner on the roasting tray to catch drips. Keep an eye on cheese and sweet marinades, as these ingredients burn quickly and stick firmly.

Clean the shelves separately. Line the bottom of a bath with an old towel. Fill it with hot water and a little soap, then leave the shelves to soak. A simple wipe with a sponge should then be enough. Dry them thoroughly to prevent corrosion.

Common practical questions

Does the technique damage the coating?

Using a light touch and keeping the coin flat helps to limit marks. A discreet test will confirm whether the surface is compatible. If you notice dullness or fine scratches, stop and switch to a melamine sponge or microfibre cloth.

Can it be used on a catalytic oven?

Avoid all abrasive materials on these liners. The active coating absorbs grease and then cleans itself when heated. Wiping with a damp cloth after cooking improves the result. Allow the catalytic cleaning cycle to work as stated in the manual.

What about the glass door?

Use a window scraper fitted with a new blade, held at a shallow angle on a wet surface. Wipe regularly. A coin is not well suited to glass, especially near printed markings.

Going further: hygiene, energy and durability

A clean interior produces less smoke during preheating. Greasy odours are reduced. The oven reaches temperature more steadily, which limits fluctuations and reheating cycles. Seals last longer when grease is not allowed to build up. You replace fewer accessories and maintain consistent performance.

This product-free approach avoids solvent emissions. It cuts down on empty packaging and transport associated with cleaning products. It costs almost nothing. All it requires is a little method and a short routine after messy cooking.

Useful additional information

• Cleaning frequency: carry out a quick wipe after every messy cook and targeted cleaning every 2 to 3 weeks.
• Persistent odours: place a dish of water inside during a short preheat. The steam softens residues before wiping.
• Mineral deposits: if your water leaves marks, always dry the walls and glass after rinsing.
• Food safety: do not allow meat drips to remain. Wipe them away as soon as possible to limit odours and smoke.

“Fewer products, more control: gentle, regular and targeted mechanical action is enough to keep an oven clean for longer.”
