How to Clean Bricks on a Fireplace

Introduction

Fireplace bricks naturally collect soot, smoke stains, and grime over time. Cleaning them restores their appearance and prevents buildup that can become harder to remove. With the right tools and method, you can freshen your fireplace safely and efficiently.

What You'll Need

• Soft-bristle scrub brush

• Bucket of warm water

• Mild dish soap

• Baking soda

• White vinegar (optional)

• Microfiber cloths

• Spray bottle

Steps

Mix warm water with a few drops of dish soap in a bucket.
Dip a soft-bristle brush into the soapy mixture and scrub the brick in circular motions.
For stubborn stains, apply a paste of baking soda and water, let it sit for 10 minutes, then scrub.
Rinse the bricks with a clean damp cloth to remove residue.
Allow the fireplace to air dry completely before using it again.

Alternative Methods

• Use a vinegar-and-water spray for light soot stains

• Use a commercial masonry cleaner designed for indoor fireplaces

• Use a steam cleaner for deep cleaning without chemicals

What NOT to Do

• Do not use wire brushes, which can damage the brick surface

• Do not use harsh acids unless they are specifically safe for interior masonry

• Do not clean bricks while the fireplace is still hot

FAQs

How often should I clean my fireplace bricks?
