Sometimes, yes. If your non-stick pan has started sticking because of a baked-on build-up of grease and food residue, a long soak, a bicarbonate of soda paste and a light wipe of oil can bring it back. If it still sticks after a thorough clean, or the coating is scratched down to the metal, blistered or flaking, the non-stick is gone for good: a worn coating cannot be restored at home.
Key points
- Clean first, judge second: soak, bicarbonate paste, soft sponge, then a thin film of oil.
- Tefal lists overheating, too little oiling, burnt food and residue build-up as the reasons a non-stick pan starts sticking.
- Tefal advises against salt, cooking sprays and heating oil until it smokes on non-stick.
- Deep scratches, blistering or flaking mean the coating cannot be saved.
This article goes deeper into one part of our guide on why food sticks to a pan, which covers every material. Here we only deal with coated pans: PTFE (often sold as Teflon) and ceramic.
Why is my non-stick pan sticking? Residue or a worn coating
A sticking non-stick pan usually has one of two very different problems. In its instructions for use, Tefal gives four reasons food starts to stick: the pan has been overheated, it has not been oiled regularly enough, food has burnt in it, or residue has built up. Build-up and burnt food can be removed. A coating damaged by heat or simply worn out cannot.
| What you notice | Likely cause | Can it be fixed? |
|---|---|---|
| Surface feels dull or tacky, no scratches | Baked-on film of grease and food residue | Usually |
| Whitish, chalky layer, often after cooking vegetables in hard water | Limescale deposits | Yes, with diluted white vinegar (Tefal) |
| Sticks in patches, with dark marks | Burnt residue or overheating | Residue yes; heat-damaged coating no |
| Deep scratches, bare metal, blistering, flakes | Damaged coating | No |
| Still sticks after a thorough clean, on a medium heat with a little fat | Worn non-stick | No |
Not every change in colour is a warning sign: Tefal says minor discolouration of the coating is normal with use and does not affect its non-stick properties.
How to restore a non-stick pan that has started sticking
Before you decide the pan is finished, give it one proper clean. These steps follow Tefal's own advice:
- Let it cool. Which? advises letting a pan cool naturally before washing, to avoid warping.
- Soak it. Fill with water and washing-up liquid. For build-up, Tefal suggests leaving it overnight.
- Use a bicarbonate of soda paste. Mix bicarbonate of soda with a little water and rub it gently over the pan with a non-abrasive sponge (Tefal).
- Keep the scourers away. Tefal UK recommends bicarbonate paste rather than salt or scouring pads on non-stick, and a soft sponge.
- Tackle limescale with acid. Tefal removes chalky deposits with diluted white vinegar or lemon juice.
- Dry and oil lightly. Tefal calls this conditioning the coating (see below).
Then test it. Fry an egg on a medium heat with a little butter or oil. If it slides, the problem was residue. If it sticks again, the coating is worn. Which? uses the same kind of egg test after its abrasion test, in which pans are vibrated with 500 steel nuts for ten minutes to simulate wear. If the base is actually burnt black, follow our guide on how to clean a burnt pan.
How to make a non-stick pan non-stick again: do the hacks work?
Here is what manufacturers and consumer bodies say about the popular fixes.
Salt
Scrubbing or heating coarse salt in a pan is a cast iron and carbon steel technique: German iron pan maker Turk uses it as a gentle abrasive. For non-stick, Tefal UK says to stick to bicarbonate paste rather than salt. We found no manufacturer of coated pans and no consumer organisation recommending salt on a non-stick coating, so it is best avoided.
Seasoning a non-stick pan with oil
There is some truth in this one. Tefal does tell owners to oil the coating, but very lightly: before first use, wash and dry the pan and rub a little cooking oil into the coating. Its detailed instructions describe warming the pan on a low heat for 30 seconds, taking it off the heat, spreading a teaspoon of oil with kitchen paper and wiping off the excess, then repeating this regularly, especially after a dishwasher cycle.
That is very different from seasoning cast iron, where oil is heated hard. Tefal says never to heat fat or oil until it smokes, and recommends medium temperatures because high heat can damage the coating. And no amount of oiling will bring back a worn coating: asked whether a pan can be re-coated, Tefal answers that the non-stick coating must be applied during the initial manufacturing process.
Non-stick repair sprays
Sprays sold to restore a damaged non-stick surface are easy to find online. We found no independent test of them by Which? or any other consumer organisation, so there is no evidence that they work. The only firm statement comes from Tefal: the coating is applied when the pan is made.
Just add more oil?
Tefal's German website puts it plainly: when food sticks even in a coated pan, adding more oil to the damaged pan is not the answer; replacing it is.
New non-stick pan sticking: common causes
Before blaming the pan, check these first:
- Skipping first-use preparation. Which? advises handwashing a new pan before using it for the first time, and Tefal adds a light rub of oil.
- Too much heat. Tefal highly recommends medium temperatures. On an induction hob, its care guide says never to heat an empty pan and to preheat on a medium setting.
- Cooking spray. Tefal's instructions say never to use non-stick cooking sprays; its care guide explains they can leave an invisible film that affects the non-stick properties.
- Extra virgin olive oil in a ceramic pan. Germany's consumer testing body Stiftung Warentest recommends refined oils such as rapeseed or sunflower for ceramic coatings.
- The dishwasher. Which? says always handwash non-stick, even when a pan is labelled dishwasher-safe.
Tip: Tefal's care guide states that food sticking because of overheating, too little oiling or residue build-up is not covered by its guarantee. A claim is more likely to succeed for blistering or a coating that peels in normal use.
When to give up: why every non-stick coating wears out
A non-stick coating is a thin layer applied over the body of the pan, and cooking, washing and utensils wear it down over time. Testers measure exactly this: Which? checks scratch resistance and simulates wear with an abrasion test, and Germany's Verbraucherzentrale says the non-stick effect of PTFE pans fades after three to five years depending on use, and sooner for ceramic. Tefal itself suggests replacing non-stick and ceramic pans ideally every two to three years; that is a manufacturer's recommendation, not a test result.
Your pan is finished when:
- the coating is blistering, flaking or showing bare metal;
- deep scratches run across the cooking surface;
- food still sticks after a thorough clean, on a medium heat with a little fat.

What next? Frying pans without a coating
If you would rather not face the same question every few years, uncoated frying pans have no layer to wear away: stainless steel, cast iron, carbon steel and titanium. They ask for a different technique instead: proper preheating, a little fat, and seasoning for cast iron and carbon steel. Our guide to the uncoated frying pan compares them.
One option is the Untitan pan: titanium cooking surface, uncoated, PFAS-free. Its hammered surface, well preheated with a little fat, helps food release, and its stainless steel base works on every hob, induction included. To be fair about the trade-offs: titanium conducts heat much like stainless steel, so it needs preheating, and it costs more than an entry-level non-stick pan. The rest are set out in titanium cookware pros and cons.
Frequently asked questions
Can you get the non-stick back on a pan?
Only if residue is the cause: soak, clean with bicarbonate paste and a soft sponge, then oil lightly. A worn or scratched coating cannot be restored; Tefal says it can only be applied during manufacture.
Why is my Tefal pan sticking?
Tefal points to residue build-up, overheating, burnt food or not oiling the coating regularly. Clean it thoroughly first; if it still sticks, the coating is likely worn.
Does salt fix a sticking non-stick pan?
There is no evidence it does. Salt is a cast iron technique, and Tefal UK recommends bicarbonate paste rather than salt on non-stick.
Why is my new non-stick pan sticking?
Usually too much heat, cooking spray residue or skipping the first wash and light oiling. Tefal also advises never heating an empty pan on induction.
