Always let your cooktop cool before you touch or work on it. You don’t want to burn yourself!
If this doesn’t work, you can either repeat the process or try another solution. If it looks like the scratch is starting to disappear, giving baking soda another shot may be a good idea. If you can run your finger over the scratch and you don’t feel any gaps, it’s probably small enough to qualify as a minor scratch.
Any white toothpaste with baking soda in it will work for this. The gel-style toothpastes likely won’t work as well. If toothpaste and baking soda don’t work, you’re likely going to need to use polish and an orbital sander.
After you cover the scratches 3-4 times with your pad, your scratches should be totally gone! If this doesn’t work, you’re going to have to fill the scratch in with a glass filler kit or replace the cooktop.
You can paint the filler after it dries if you want it to match the rest of the cooktop. You can line the edges of a crack with painter’s tape if you’re worried about the epoxy getting everywhere. If the edge of your cooktop is cracked and it’s exposed, place a popsicle stick flush on the edge where the crack is located and tape it to the cooktop with painter’s tape. So long as the side of the popsicle stick is higher than the top of the cooktop, you’ll have no problems filling in the gap. [6] X Research source
Wear cut-resistant gloves and use a vacuum to pull up any broken shards of glass before you replace the cooktop once it arrives. While it varies drastically from brand to brand and model to model, you can expect to spend $100-200 on the replacement glass.
Steel wool, the abrasive side of a sponge, and a brillo pad are all going to scuff or scratch the surface.
