Cooktop Scratched? Repair or Replace

Assess the scratch first

Before deciding between repair and replacement, look closely at the scratch on your slide-in range's cooktop. A light surface scratch from a pan bottom or a grain of grit may only affect the look, not the function. A deep scratch, chip, or crack can weaken the glass and create a safety risk, especially on a radiant or induction cooktop where the surface heats up during cooking.

Run your fingernail gently across the mark. If it catches, the scratch is likely deeper than the surface layer. If the mark is a crack or a chip with sharp edges, stop using the cooktop immediately. The maker's manual and a qualified service technician are the right sources for a structural assessment. The site's guides compare stated details only, so they cannot tell you whether a specific scratch is safe to keep cooking on.

• Light surface scratches: often cosmetic, may be reduced with a polish kit
• Deep scratches that catch a fingernail: may need professional evaluation
• Cracks, chips, or shattered glass: stop using the range and call a service technician

Repair options for cosmetic scratches

For light scratches that do not catch a fingernail, a cooktop polishing kit can help reduce their appearance. These kits typically include a polishing compound and a pad, and they work by gently buffing the surface. Always follow the instructions that come with the kit, and try it on a small, hidden corner of the cooktop first.

Some makers sell their own cooktop cleaner and polish, and the manual for your range may recommend a specific product. The LG range page mentions EasyClean for the oven, but it does not describe cooktop scratch repair, so rely on the manual that came with your appliance. Avoid using abrasive pads, harsh scouring powders, or razor blades on a glass cooktop, as these can make scratches worse.

When replacement is the only option

A cracked or chipped glass cooktop is not something a repair kit can fix. The glass is a single piece, and any structural damage can spread with heat or pressure. Continuing to use a damaged cooktop can lead to a larger break, which is a safety hazard. In that case, you need to replace the cooktop or the entire range.

Replacing the cooktop is a job for a qualified service technician, not a do-it-yourself project. The technician will need the model and serial number from your range to order the correct part. If the range is older or the part is no longer available, replacing the whole range may be more practical. The site's buying guides can help you compare new slide-in ranges by stated details, such as fuel type, width, and oven capacity.

Prevent future scratches

Once you have repaired or replaced the cooktop, you can take steps to avoid new scratches. Use cookware with smooth, flat bottoms and avoid sliding pots and pans across the surface. Lift the cookware instead of dragging it. Wipe up spills with a soft cloth or sponge and a cleaner made for glass cooktops.

The USFA cooking safety page advises staying in the kitchen while cooking and turning the burner off if you leave. That advice is about fire prevention, but it also means you are present to catch a spill before it bakes on and becomes harder to clean. Keeping a lid or baking sheet nearby, as the USFA suggests, is a good habit for any cooktop.

What the guides can help with

If a scratched cooktop leads you to shop for a new slide-in range, the site's guides compare models on stated details only. You can filter by fuel type, width, and features like convection or air fry. For example, the best induction slide-in ranges guide lists models with induction cooktops, which use a smooth glass surface that can scratch just like a radiant cooktop.

The best slide-in range guide is a good starting point for a general overview. If you are comparing by width, the 30 inch and 24 inch guides can help. For a specific brand, see the GE, Samsung, or Bosch guides.

What to pick for your situation

Questions

Can I use a repair kit on a cracked glass cooktop?

No. A repair kit is only for light surface scratches. A crack or chip weakens the glass, and using the cooktop can cause it to break further. Stop using the range and contact a qualified service technician.

Will a polishing kit remove deep scratches?

A polishing kit can reduce the appearance of light scratches, but it will not remove deep scratches that catch a fingernail. For deep scratches, check the maker's manual or ask a technician whether the cooktop needs replacement.

Is it safe to cook on a scratched glass cooktop?

If the scratch is only cosmetic and the glass is not cracked or chipped, it is generally safe to continue using the cooktop. However, if the scratch is deep or you see any crack, stop using the range and have it inspected.

How do I find the right replacement cooktop?

You will need the model and serial number from your range, which are usually on a label inside the oven door or on the back of the unit. A qualified service technician can order the correct part for your specific model.

What should I do if the scratch is from a pan that melted onto the cooktop?

Melted plastic or metal can be difficult to remove and may scratch the surface if you scrape it. Let the cooktop cool completely, then follow the maker's cleaning instructions. If the surface is damaged, contact a technician.

Can I prevent scratches on a new cooktop?

Yes. Use cookware with smooth, flat bottoms, lift pans instead of sliding them, and clean with a soft cloth and a cleaner made for glass cooktops. Avoid abrasive pads and harsh scouring powders.
