Can you clean a fireplace insert glass with razor blade?

No, it is not recommended to clean a fireplace insert glass with a razor blade. The glass on fireplace inserts is usually made of a ceramic or glass material that can be easily scratched or damaged by sharp objects like razor blades. If the glass is scratched or damaged, it can cause the fireplace to become less efficient or even dangerous.

There are much safer and effective ways to clean fireplace insert glass. Some methods that you can try include:

1. Using a glass cleaner: Spray a glass cleaner onto the insert glass and wipe it off with a soft, lint-free cloth.

2. Using warm water and a mild detergent: Mix a solution of warm water and a mild detergent, and use a soft cloth to clean the glass. Be sure to rinse the glass thoroughly to remove any residual detergent.

3. Using a commercial fireplace cleaning product: There are many commercial fireplace cleaning products available that are specifically designed for cleaning fireplace insert glass. Be sure to follow the instructions on the product label carefully.

4. Using a dryer sheet: Dryer sheets can help to remove dust and lint from fireplace insert glass. Rub the glass with a dryer sheet and then wipe it off with a clean, dry cloth.

No matter which method you choose, be sure to avoid using any sharp objects or abrasive cleaners, as these can damage the glass. If you are unable to clean the glass yourself, you may want to call a professional chimney sweep to have it cleaned.
