How to Remove Burnt-On Marks from an Induction Cooktop Without Scratching It
Why You Should Not Scrub Burnt-On Marks with a Scouring Pad
An induction cooktop is built with a thin ceramic coating over tempered glass. When soup or sauce boils over and hits a surface close to 250 degrees, sugars and proteins caramelize almost instantly and stick as if embedded in the glass. If you use steel wool or a rough scouring pad on it, fine hairline scratches form in the coating, and the next stain will settle into those scratches more easily. The key is not to scrape by force, but to soften the residue and lift it off.

Supplies and Exact Amounts
- 1 tablespoon baking soda (about 12g)
- 2 tablespoons lukewarm water (about 30ml)
- 1 plastic scraper made for induction cooktops or one 45-degree razor scraper
- 2 microfiber cloths
- 3 to 4 dry paper towels
A 15-Minute Process
- Check with the back of your hand that the cooktop has cooled to lukewarm. Start only when it is completely cool or lukewarm.
- Mix 1 tablespoon baking soda and 2 tablespoons water in a small bowl to make a paste about as thick as toothpaste.
- Spread the paste over the burnt-on mark in a 1mm layer, then place a water-dampened paper towel on top.
- Leave it for 10 minutes. During this time, the hardened sugars will soften.
- Remove the paper towel, then hold the scraper at a 15 to 20-degree angle against the cooktop and push from the outside of the mark toward the center. Never hold it upright.
- Wipe away the loosened residue and paste with a damp microfiber cloth, then finish by wiping once more with a dry cloth.
Combinations You Should Never Mix
Some people add vinegar or bleach (sodium hypochlorite) when baking soda does not remove the mark, but mixing bleach with acidic cleaners or vinegar can produce chlorine gas and is extremely dangerous. Mixing bleach with ammonia-based cleaners can also release toxic gas. Use only one cleaner at a time on an induction cooktop, and if you want to try another product, rinse thoroughly with water first. If a rainbow-colored stain remains, it is not a scratch but limescale and mineral residue. Apply a pea-sized amount of induction cooktop cream cleaner to the cooled surface and wipe in circles to remove it.
