The first time you spot it, your heart drops. The once sleek black glass cooktop now shows a pale, uneven scratch cutting across the surface. It may have happened when a heavy pot slid too fast or when a tiny grain of salt lodged itself beneath a pan. The mark is small, yet your eyes go straight to it every time you walk into the kitchen. Running your fingers over the glass, you can feel the roughness, and the worry sets in—has the cooktop been permanently damaged, or is there a way to fix it?
Why Glass Cooktops Scratch Even With Careful Use
Glass cooktops look smooth, modern, and durable, giving the impression they can handle daily cooking without issue. In reality, the surface is more delicate than it appears. Minor abrasions can develop despite careful habits. Sliding heavy cookware, a grain of salt trapped underneath, or using cast-iron pans with rough bases can quietly leave marks behind. Often, these scratches only become noticeable during cleaning, bringing a familiar sense of frustration. The reassuring news is that many scratches are not permanent and can often be reduced with gentle care.
Assessing the Damage Before You Start
Before attempting any repair, it’s important to understand how deep the scratch is. Examine the cooktop under bright light and from different angles. If the mark only appears at certain angles and your fingernail doesn’t catch on it, it’s likely a light surface scratch. If your nail catches slightly, the damage may still be manageable. Deep grooves that clearly catch your nail are more serious and cannot be fully removed at home. Thinking in terms of light haze, visible lines, and deep grooves helps set realistic expectations.
Choosing the Right Tools: Gentle Is Key
Start by cleaning the cooktop thoroughly so no grease or residue interferes with the process. Use a cooktop-safe cleaner and a soft cloth, then dry the surface completely. For polishing, stick to mild options only. Baking soda paste, non-gel toothpaste, ceramic cooktop cream, or a glass polishing compound are suitable for light to moderate scratches. These products smooth the surface gradually rather than grinding it down. Always use a soft microfiber cloth and avoid abrasive sponges, steel wool, or gritty tools that could cause further damage.
At-Home Techniques to Reduce Scratches
Always test your chosen method on a small, hidden area first. If the finish remains clear, move on to the scratch. For light marks, apply baking soda paste or toothpaste and rub gently in small circular motions. Wipe the area clean, check the results, and repeat if needed. For more noticeable scratches, ceramic cooktop cream or glass polishing compound is often more effective. Use light pressure and patience, allowing the product to work gradually. While deep scratches won’t disappear entirely, careful polishing can soften their appearance and make them far less noticeable.
Restoring Shine After Polishing
Once the scratch looks improved, clean the area again to remove any leftover residue. Many people like to finish with a cooktop cleaner that leaves a subtle protective shine. Buff gently using a dry microfiber cloth until the surface reflects evenly. The scratch may still be faintly visible, but it usually blends into the background instead of standing out.

Common Scratch-Reduction Methods at a Glance
- Baking soda paste: Best for minor surface marks and dull patches; affordable and gentle, but ineffective on deep scratches.
- Non-gel toothpaste: Works on light but visible scratches; easy to apply, though repeated attempts may be needed.
- Cooktop polishing cream: Designed for light to moderate damage; safely restores shine but costs more than household options.
- Glass polishing compound: Helpful for stubborn or multiple scratches; offers stronger results but requires careful use.
How to Prevent Future Scratches
Preventing scratches often comes down to small habit changes. Lift cookware instead of sliding it. Wipe the bottoms of pots and pans before placing them on the glass. Clean spills—especially salt or sugar—before cooking again. Avoid storing heavy or rough cookware on the cooktop surface. If you use protective covers or mats, make sure they are specifically designed for glass cooktops and safe for heat.
When Repair Isn’t Enough
If a scratch looks more like a crack, continues to spread, or feels deeply gouged, it’s best to stop and seek professional advice. Structural damage can affect how the glass handles heat and may pose a safety risk. That said, most everyday scratches are purely cosmetic and don’t require replacement. With patience and gentle methods, you can restore much of the cooktop’s smooth appearance.
Caring for Your Glass Cooktop Over Time
A glass cooktop is both practical and reflective, showing signs of daily use as time goes on. Scratches don’t always signal neglect—they’re often a natural result of regular cooking. Knowing how to reduce and manage them helps keep your kitchen looking tidy and calm. More importantly, it builds confidence in caring for your appliance, allowing you to focus on cooking instead of worrying about every small mark.
