If you just bought a new stove with a glass cooktop, and own lots of cast iron pots and pans, don’t despair. Using cast iron on a glass top stove can be done safely and we’ll show you just how. This article will look at how to protect glass top stove from cast iron equipment.

How to Protect Glass Top Stove from Cast Iron Pans

Cast iron cookware is heavy-duty and can be rough on your stovetop and counters. These steps will help you safely use cast iron on an electric stove and cooktops. When followed carefully, you won’t have to replace a glass stovetop every few months!

Lift Your Pans:

It can be tempting to slide your cast iron pan across the glass cooktop once you’re done cooking. After all, cast iron weighs a ton and can be hard to lift. But lifting your pots and pans go a long way in working as a glass stove top protector.

Because cast iron is rough and heavy, sliding it on the glass surface can cause tiny cracks that will eventually lead to the cooktop shattering. So instead of dropping a pot on the glass or sliding them off, gently lift them or place them down on the stove to prevent damage.

Season Your Entire Pan:

If you want to prevent scratches on glass cooktop, this is the way to go. Most people only season the inside of their favorite skillet, leaving the outside rough and bumpy. This bumpy surface can wear away your glass cooktop, breaking it out of the blue eventually.

Cast iron cookware seasoned with cooking oil will have a carbonized layer on the pan, which is essentially non-stick.

Coat the entire pan in oil, and put upside down it in the oven at a high temperature. This will create a smooth, even layer of seasoning on the cast iron cookware that will be coming into contact with your glass top stove.

As the smooth bottom cast iron skillet is even, it will greatly decrease the chances of scratching your glass top stove and will also provide the best protection possible when you use cast iron on a glass top stove.

Use Heat Diffusers:

Investing in a heat diffuser is one of the simplest ways to extend the life of your glass cooktop. A heat diffuser for an electric glass-top stove will diffuse the heat and dispense it throughout the bottom surface of a pan. Your range top heat diffuser will also protect the delicate surface from heavy and rough pots and pans.

Think of the diffuser as a buffer between the glass cooktop and the things you put on it. The diffuser is made from light, yet durable metal. This may be the cheapest and most convenient way to prevent your cooktop from cracking or scratching.

Get a Glass Cooktop Protector:

This is another easy way to prevent damage to your stove surface. A protector for glass/ceramic stove top is a thin cover that keeps your cooktop safe. They are made from rubber or silicone and are anti-slip and heat resistant.

A heat resistant glass stove top cover will also protect your stovetop from spills, grime, and scratches. They are also easy to clean and are foldable. 

A glass top stove protective cover is another buffer between your glass cooking surface and cast-iron skillet. You can also use a ceramic stove top protector if you can’t find one meant for glass cooktops.

Keep Everything Clean:

Keeping grime and grease at bay may be the simplest way to protect glass top stoves in the long run. This means regularly cleaning both your cast iron cookware and your stovetop.

Clean your cast iron cookware with warm water, dish soap, and a sturdy sponge. Get rid of any grease and bits of food stuck to the bottom of the pan. Meticulously cleaning these spots will prevent burn marks and scratches from appearing on your glass cooktop.

You should also wipe down the stove surface after cooking every day to remove grease, spilled food, and grime. Once a week, give your cooktop a good deep clean. Remember, the aim is to prevent grime from building and staining your new, shiny stove!

Here are a few things you can do to prevent and remove scratches from your glass cooktop:

  • Use a cooktop protector mat and change it when it is worn out. It is also important to clean these covers once a week, or after a hectic and substantial cooking session.
  • Don’t slide your pots and pans back and forth along your stove. Lift them away and set them down gently instead.
  • Use lightweight pots and stainless-steel cookware whenever possible.
  • Scrub the bottom of your pots and pans regularly and remove the grease and burnt bits of food there.
  • Clean spills right away and never use steel wool and metal sponges on your glass cooktop.
  • Avoid using aluminum foil on these kinds of stoves as they can leave marks and scratches on the delicate cooking surface.
  • To fix small scratches, make a paste from baking soda and water and gently buff away the scratch with this mixture. Make sure the paste is wet and rubbing dry baking soda will make the damage worse.
  • To keep your glass cooking surface looking new, use glass cleaner to keep things clean and shiny.
  • Follow manufacturer’s instructions when using and cleaning your stove and cookware.
  • Regularly season the entire surface of your cast iron cookware. You should also use newer versions of cast iron skillets as these have much smoother bottoms than older ones.
  • Avoid using cookware with round bottoms as they cause scratches. Instead, use pots and pans with smooth and flat bottoms, as they are more stable and will shift around less, reducing the chances of scratching up your glass cooktop.

Strategies to Clean Glass Stove Tops
