The first time you see it your heart drops. That glossy black glass cooktop you once loved now has a light jagged scratch going across it. Maybe it showed up when you slid a heavy pot too fast or when a small grain of salt got trapped under a pan. The scratch is tiny but every time you walk into the kitchen you notice it right away. When you run your finger over the surface you can feel the rough edge. You start to think the damage might be permanent and wonder if you need to replace the whole cooktop or just live with the flaw.
Assessing the Scratch: How Bad Is the Damage?
Before attempting any repair, it’s important to identify the type of scratch on your cooktop. Examine the surface under bright lighting and from multiple angles. If the mark is visible only at certain angles and your fingernail doesn’t catch, it’s likely a minor surface blemish. These are generally the easiest to improve. If your nail catches just a little, the scratch may still be treatable. However, deep grooves that clearly snag your nail are more serious and cannot be fully removed at home. Thinking in terms of light haze, visible lines, and deep scratches helps you choose the right method and manage expectations.
Choosing the Right Supplies: Gentle Is Best
Start by cleaning the cooktop thoroughly to remove grease, dust, or residue that could interfere with polishing. Use a soft cloth with a cooktop-safe cleaner, then dry the surface completely. When it comes to scratch reduction, stick to mild, non-abrasive options. Baking soda paste, non-gel toothpaste, ceramic cooktop cream, or a glass polishing compound are all suitable for light to moderate marks. These products work by gently smoothing the surface, not grinding it down. Always use a soft microfiber cloth and avoid harsh pads, steel wool, or gritty materials that could cause more damage.

Simple Home Techniques to Minimize Scratches
Before treating the main area, test your chosen method on a small, less visible spot. If the finish remains clear, you can proceed. For light scratches, apply baking soda paste or toothpaste and rub gently in small circular motions. Wipe the area clean, check the results, and repeat if necessary. For more noticeable marks, ceramic cooktop cream or a glass polishing compound often delivers better results. Use light pressure and patience, allowing the product to do the work. While deep scratches won’t vanish, careful polishing can soften their appearance and make them far less obvious.
Restoring the Finish After Polishing
After you’re satisfied with the improvement, clean the surface again to remove any remaining residue. Many people finish by using a cooktop cleaner that leaves a subtle protective shine. Buff the area gently with a dry microfiber cloth until the surface looks even and reflective. The scratch may still be faintly present, but it usually blends into the surface instead of standing out.
Why Glass Cooktops Get Scratched Even With Care
Glass cooktops appear smooth, modern, and almost indestructible, giving the impression they can handle everyday cooking without issue. In reality, the glass is more delicate than it looks. Small abrasions can form even with careful use. Sliding a heavy pot, a grain of salt trapped beneath cookware, or a cast-iron pan with a rough base can all quietly leave marks. Often, the scratch isn’t noticed right away and only becomes visible during cleaning. The key takeaway is that many of these scratches aren’t permanent and can often be reduced with gentle, proper care.
