How to Repair a Damaged Glass Cooktop

A glass cooktop is among the appliances that give your kitchen a perfectly modern look. You will not struggle to clean any mess that spills on it. Unfortunately, failure to maintain it properly results in some ugly scratches or even dangerous cracks that can cause electric shock. So, what causes it to crack or get scratches?

Causes of Cooktop Damage

Wiping With Abrasive Materials

When cooking, the chances of food particles spilling on the cooktop are high. But what do you use to wipe out the mess? Instead of using a soft cloth or sponge, some use steel wire or even a scrubby sponge. As a result, the cooktop gets some scratches.

Wrong Cookware's

If you drag cookware with irregular surfaces on your cooktop, the chances of causing scratches are high. So, if possible, use cookware with flat surfaces and avoids dragging anything on your cooktop. Also, ensure that the cookware has no paint on the bottom since it can melt and stain your stovetop. 

Misusing The Stovetop

Why should you use the glass cooktop as a chopping board? Though the surface is flat and smooth, the manufacturer never designed it as a chopping board. The knife will leave small scratches, which will deepen with time, causing serious cracks. 

Heavy Objects

Once the food is ready, do you leave it to cool on the cooktop? Then that's a recipe for cracking your cooktop. No matter how tired you get after cooking, never lean on your cooktop. The manufacturer has not designed it to support heavyweight. 

Cleaning Mistakes

You don't want anything to mess the beautiful shinny look of your cooktop. But do you wait for the cooktop to cool before cleaning it? If you want your cooktop's finishing to last longer, then use cleansers only when the cooktop cools. Again, be careful of the cleaners that you use. Some glass cleaners such as Windex, have strong ammonia that can easily damage your cooktop.  

Regulator Failure

The glass cooktop has a temperature regulator that protects it from overheating. If the regulator fails, excess heat will cause the cooktop to crack. 

Is It Safe To Use A Damaged Cooktop? 

If you notice that your glass cooktop has some cracks, avoid using it. If it has scratches, you can repair it easily. But if it has cracks, the chances of electric shock are high. You need to replace the cracked surface first before using it. 

Repairing Scratches

Knowing the secret on how to remove scratches from the glass stovetop will save you from incurring high repair costs. It will also protect the scratches from worsening and becoming cracks. There are several methods of fixing scratches. Check some of the two methods below.

Using Baking Powder Paste

Start by accessing how deep the scratchers are. If there are too deep, then you may have to replace the ceramic glass top surface. But if the surface has light scratches, then arm yourself with water and baking powder. Here is the process

1. Make a wet baking powder paste 

2. Apply it on the scratched surface and rub it gently

3. Wipe the excess paste and clean the surface

4. Dry it and use your glass stovetop.

Clear Nail Polish

You require a clear nail polish, glass polish, and a buffing pad. Check the process below.

1. Apply the clear nail polish on the scratches, wipe any excess and let it dry.

2. After an hour, buff the surface using a buffing pad softly to avoid making the surface dull. Excess buffing can also worsen the scratch. 

3. Add some glass polish and continue buffing the surface in the circular motion.

4. Let it dry before using the glass stovetop.

Fixing a Cracked Glass Cook Top

In case of crack, you need to order another glass cooktop from your manufacturer. If you don't mind, the hardware near you may be selling some glass cooktops. If the two options are not available, order them online. Once you get it, follow the process below.

1.  Switch off the power-Trying to dismantle your stove cooktop before switching it off is dangerous. You are likely to get an electric shock.

2.  Read the manual- If it's your first time to replace, go through the manual first. The internet could offer you a soft copy if you misplaced the hard copy. 

3. Unscrew it-Use that knowledge to unscrew your glass cooktop. 

4.  Label the wires-Note that before disconnecting the wires, you must label them to avoid confusion. 

5.  Replace-Lift your glass top and replace it with the new one.

6.  Restore it back-Do the reversal of the process above and use your glass top.

Rust, Burns, and Plastic Stains

You already know how to fix the scratches and cracks. But how do you deal with rust, tough burns, and plastic stains? If a plastic melts on your burner, you need to switch off the burner first before removing it. A metal spatula will help you remove the plastic melt without scratching the surface.

Make sure you have the oven mitt to avoid burning your figures. Wipe the mess with a paper towel before washing it with the right non-abrasive cleaner. 

In case of tough burns and rust, use an applicator pad to rub them off smoothly. Use the right cleaner and restorer for perfect results. 


A glass cooktop gives your kitchen a beautiful modern look. If some mess spills on it when cooking, you can easily clean it. It makes your cooking easier and safe since the area around the burner doesn't heat up. Its ease of maintenance makes many households use it. Unfortunately, it can get scratches or even crack. You can fix the scratches easily using baking powder paste. Clear nail polish can also act as a substitute. Cracks leave you with the option of replacing and not repairing. You require the manual to get the direction of dismantling the glass stove top and replacing the cracked surface. After replacing, take care of your glass stovetop to avoid unnecessary costs. Remember placing a heavy object on it or even using it as a chopping board is not recommended.
