Deep Cleaning Fireplaces and Hearths

Yes, Jacksonville Homes Have Fireplaces

It surprises people who haven't lived here, but many Jacksonville homes have fireplaces. From the wood-burning fireplaces in Riverside's historic homes to the gas units in modern builds in Nocatee, fireplaces are common across Northeast Florida. And while we don't use them as often as folks in Boston, the few months we do use them — typically December through February — they accumulate soot and creosote that needs regular deep cleaning.

The National Fire Protection Association recommends annual fireplace inspection and cleaning, even for occasional users. Here's how to deep clean your fireplace and hearth properly.

Safety Before Cleaning

Before you start, ensure the fireplace is completely cold and has been unused for at least 24 hours:

• Never clean a warm fireplace — residual heat can cause burns
• Wear an N95 mask to avoid inhaling soot and creosote particles
• Wear safety goggles to protect your eyes from ash dust
• Spread a heavy drop cloth over the hearth and surrounding floor — soot stains are nearly impossible to remove from carpet and upholstery
• Keep a trash bag and a bucket nearby for waste

Wood-Burning Fireplace Deep Clean

Step 1: Remove Ash

• Shovel the bulk of the ash into a metal bucket — never use a vacuum for this step, as live embers can hide in ash and destroy your vacuum
• Use a shop vac for the remaining fine ash only after you're certain there are no embers
• Scoop ash from the firebox floor and the ash dump if your fireplace has one
• Dispose of ash in a metal container with a lid, stored outside away from combustibles
• Leave about an inch of ash — it actually helps the next fire start more easily

Step 2: Clean the Firebox

• Scrub the firebox walls with a stiff wire brush to remove loose soot and creosote
• Apply a paste of cream of tartar and water to stubborn soot stains, let sit 10 minutes, scrub
• For brick fireboxes, use a masonry cleaner or TSP solution
• For metal fireboxes, use a degreaser safe for the metal type
• Rinse with a damp sponge — don't saturate the masonry

Step 3: Clean the Damper and Smoke Shelf

• Reach above the damper with a stiff brush and flashlight
• Scrape creosote from the damper blade — it restricts airflow when built up
• Clean the smoke shelf (the area just above the damper) where creosote and debris collect
• This area is the #1 spot for creosote buildup, which is the leading cause of chimney fires

Gas Fireplace Deep Clean

Gas fireplaces in St. Augustine and Jacksonville are cleaner than wood-burning but still need attention:

• Turn off the gas supply and wait for the unit to cool completely
• Remove the glass front and clean it with a gas fireplace glass cleaner — regular glass cleaner leaves a film that clouds when heated
• Clean the logs and burner with a soft brush — never wash ceramic logs with water
• Vacuum the firebox interior with a soft brush attachment
• Check the gas lines and connections for any signs of wear or damage
• Clean the exterior mantel and surround with appropriate cleaner for the material

Hearth and Surround Cleaning

Brick Hearths

• Vacuum loose soot and debris first
• Scrub with a solution of 1/2 cup dish soap and 1/4 cup salt in hot water
• Use a stiff-bristle brush and work in small sections
• For stubborn stains, apply a paste of baking soda and water, let sit 30 minutes, scrub
• Rinse with a damp cloth and dry with a towel

Stone Hearths

• Use a stone-specific cleaner — acidic cleaners like vinegar will damage marble and limestone
• Scrub gently with a soft-bristle brush to avoid scratching the stone surface
• Seal natural stone hearths annually to protect against soot staining

Tile Hearths

• Clean tile with all-purpose cleaner and a sponge
• Scrub grout lines with a grout brush and oxygen bleach
• Seal grout after cleaning to prevent future soot staining

Mantel and Wall Cleaning

Soot and smoke residue travel beyond the fireplace opening:

• Wipe the mantel with a degreaser — smoke leaves an invisible film that attracts dust
• Clean the wall above the mantel with a degreasing solution, working from top to bottom
• Check for smoke stains on the ceiling — they appear as yellow-brown discoloration
• Clean fireplace tools and log holders with steel wool and a degreaser

Preventing Fireplace Mess

• Always open the damper before starting a fire and close it after the fire is completely out
• Burn only seasoned hardwood — softwoods and wet wood produce more creosote and smoke
• Have your chimney professionally inspected and swept annually
• Install a chimney cap to keep out rain, animals, and debris
• Use a fireplace screen to contain sparks and embers
