Sodium percarbonate, the active oxygen-based bleaching agent in many dishwasher tablets, starts breaking down organic matter effectively at around 60°C. This chemical reaction, not just the heat, is what makes the dishwasher tablet method work—or fail if your pan’s material can’t handle the alkaline environment.
A blackened saucepan you forgot on the hob looks more like a bin job than a weekend project. Dishwasher tablets can rescue it, but the trick only works on the right material and gets dangerous on the wrong one. This is the breakdown of what the tablet soak can do, what it can’t, and which pan you should never put it near.
The method is commonly recommended for stainless steel and enamelled cast iron, subject to the maker’s care instructions. It loosens burnt carbon with a long, hot soak, not hard scrubbing. But that same soak may dull or damage aluminium and may damage non-stick coatings. For those, there’s a safer alternative already in your laundry cupboard.
The quick, material-specific verdict:
- Stainless steel: Works well. A tablet dissolved in boiling water and left to simmer then soak loosens moderate burnt-on residue.
- Enamelled cast iron (Le Creuset, Staub): Also works. Good Housekeeping tested it on a Le Creuset casserole and reported the enamel came up like new.
- Bare cast iron: Use with caution. It will clean it, but don’t soak for hours and dry the pan thoroughly immediately after to prevent rust.
- Aluminium: Avoid. Alkaline dishwasher detergent can dull or discolour aluminium; avoid it unless the cookware maker specifically permits it.
- Non-stick: Never. Dishwasher tablets and the scrubbing they encourage may damage non-stick coatings.
If your pan is aluminium or you want a gentler all-rounder, biological washing detergent is a safer swap. For a fraction of the cost of a new pan, it’s a method worth considering before you reach for the scouring pad.
How the dishwasher tablet method works on suitable pans
This isn’t a scrub; it’s a steep. The tablet dissolves in very hot water to create a solution that helps loosen burnt-on residue over time. The result on a stainless steel saucepan can be impressive.

What you need
One dishwasher tablet (paid link)See on Amazon, a kettle of boiling water, a wooden spoon or plastic scraper, and a soft sponge or non-abrasive pad.
Step-by-step guide
- Cool the pan first. If it’s just come off the hob, let it cool until warm, not steaming. Let the pan cool before adding water, and avoid sudden temperature changes, especially with enamelled cookware.
- Dissolve the tablet in boiling water. Fill the pan enough to cover the burnt area with water just off the boil. Drop in the tablet and let it fizz and dissolve completely. A wet tablet rubbed on the surface won’t work—the dissolved solution does the cleaning.
- Simmer for 10–15 minutes. Bring the water to a gentle simmer and hold it there. Simmering helps loosen the residue.
- Leave it to cool and soak. Turn off the heat and leave the pan for an hour or longer. A longer soak may help with stubborn residue.
- Rinse and wipe. Use a soft sponge to wipe the residue away. For any stubborn patches, a plastic scraper (paid link)See on Amazon or non-abrasive pad should finish the job. Don’t use steel wool on stainless—it’ll leave visible scratches.
A tablet costs little per use, far less than a specialist cleaning paste and a fraction of the price of a new pan.
The aluminium catch: If your pan is aluminium and you’ve already tried this, you might see grey streaks or a dull patch. That may be detergent-related dulling or oxidation; stop using the product and follow the cookware maker’s cleaning guidance. For aluminium, use the biological detergent method below instead.
Biological detergent: A gentler approach
If you have aluminium cookware or want a method you can use regularly without worrying about surface reactions, biological washing detergent is a safer choice.
It works on a similar principle: enzymes that break down food-based stains. Check the product label and cookware instructions before use.
How to use it
The method is identical to the dishwasher tablet approach: dissolve a tablespoon of biological detergent powder in hot water, simmer gently, leave to soak, then wipe clean with a soft sponge. You can reuse the same solution for several pans, making it economical for regular maintenance.
It’s also what we’d recommend for anyone who cleans burnt pans regularly and wants to avoid repeatedly exposing cookware to harsh detergents.
The trade-off is minor: biological detergent may be less effective than a dishwasher tablet on very heavy, baked-on carbon. For milk boiled dry or pasta water cooked off, it handles the job. For a forgotten risotto left overnight on a low heat, you might need a longer soak or a second pass.
Baking soda and foil for stubborn carbon
For carbon that the soak methods haven’t fully shifted, there’s a more physical option: baking soda (paid link)See on Amazon and aluminium foil.
This isn’t a chemical breakdown; you’re creating a mild abrasive paste (baking soda mixed with a little water) and using scrunched-up foil as a scrubber. The combination can lift carbon that has bonded tightly to the surface.
The honest warning: it works, but it requires noticeable effort. It also carries risk. Foil may scratch some finishes; avoid it on non-stick and use caution on polished, enamelled, or brushed surfaces.
Where it fits
Try this on bare cast iron or heavily burnt stainless steel where the carbon is thick but the surface is durable enough to take light abrasion. It’s not for non-stick pans, not for enamel unless you’re extremely gentle, and not for anyone wanting to avoid scratches.
If you proceed, use soft foil (not stiff industrial stuff), work in circular motions, and test on a small, hidden area first if you’re unsure about the surface.
Recognising when a pan is beyond cleaning
Cleaning restores surfaces; it doesn’t fix structural damage or replace a worn coating. A pan is worth replacing rather than rescuing when you see any of the following:
📺 Watch: How To Clean A Burnt Pan | Good Housekeeping UK
- Peeling or flaking non-stick coating. Once the surface is compromised, food will stick regardless of cleaning. Follow the maker’s guidance on replacement.
- Chips or cracks in enamelled surfaces. Chips can expose the underlying material and may be a reason to stop using the pan. A cracked enamel surface may make the pan unsafe or unsuitable; follow the maker’s guidance.
- Deep rust pitting on bare cast iron. Surface rust scrubs off. But deep pitting can make restoration difficult.
- A warped base. If the pan no longer sits flat on the hob, it may heat unevenly. A pan that spins or wobbles isn’t just annoying—it’s a sign the metal has distorted.
If your pan shows these signs, check the maker’s warranty or replacement guidance before spending time on a clean that won’t fix the underlying problem.
Common questions about pan cleaning
Can I use dishwasher tablets on non-stick pans?
No. Dishwasher tablets and abrasion may damage non-stick coatings. For non-stick, stick to warm soapy water, a plastic scraper, and a soft sponge. If the coating is worn, the honest answer is to replace the pan.
How long should I soak the pan?
Ten to fifteen minutes of simmering is usually enough for moderate residue. For heavier buildup, let the dissolved solution cool and soak for an hour or longer. A longer soak may help loosen stubborn residue.
Does this method work on induction hobs?
Yes, provided the pan itself is induction-compatible. The hob type doesn’t affect the cleaning method; it’s the pan material that matters.
Material compatibility at a glance
| Material | Dishwasher Tablet | Biological Detergent | Baking Soda & Foil |
|---|---|---|---|
| Stainless Steel | ✅ Works well | ✅ Safe all-rounder | ✅ For heavy buildup |
| Cast Iron (bare) | Use only if the cookware manufacturer permits it; otherwise use mild washing-up liquid | ✅ Safe all-rounder | ✅ For heavy buildup |
| Enamelled Cast Iron | ✅ Tested & confirmed | ✅ Safe all-rounder | ⚠️ Use gently |
| Aluminium | ❌ Avoid (discolouration) | Use only if the cookware and detergent manufacturers permit it; otherwise use mild washing-up liquid | ⚠️ Scratches risk |
| Non-stick | ❌ Never (damage) | ✅ Recommended | ❌ Never (damage) |
Final assessment
The dishwasher tablet method is a genuinely useful trick—effective, cheap, and using something you already own. For stainless steel and enamelled cast iron, it’s the first move worth making. For aluminium, the biological detergent alternative does a similar job with less risk.
Remember, none of these methods are magic. A pan with years of accumulated carbon or one that’s been overheated repeatedly will need patience, and some damage is simply beyond what a soak can fix. Know the signs of a pan that’s past rescuing, and replace it rather than fighting a losing battle.
