Why Stone Fire Pits Need Special Care

Stone fire pits are naturally durable, but they require unique maintenance needs that differ from those of metal or concrete models. Why? Because stone is porous, it can absorb moisture, soot, and grime, especially when exposed to the elements.

Taking a few simple steps can protect the color, structure, and integrity of your fire pit. That means fewer repairs, better performance, and a longer life. Here’s more about the benefits of maintaining and cleaning a stone fire pit regularly.

Common Issues to Watch For:

  • Soot and smoke can cause staining or darkening over time
  • Moisture buildup may lead to cracking or discoloration
  • Harsh cleaning methods can damage the stone surface

How Do I Clean Stone Exterior Without Damaging It?

When it comes to cleaning fire pit surfaces, knowing what to avoid can help prevent damage and keep your setup looking great.

Routine cleaning (monthly or after heavy use):

  • Use a soft-bristle brush to sweep off debris, ash, or soot
  • Mix warm water with a few drops of mild dish soap
  • Wipe the surface with a sponge or soft cloth
  • Rinse with clean water and let it air dry completely

Deep cleaning (every few months):

  • For tough stains, use a stone-safe degreaser or non-acidic cleaner
  • Avoid bleach, vinegar, or harsh chemicals; these can damage the stone
  • Never use a pressure washer, which can force water deep into the pores

Should I seal the stone, and how often?

Yes, sealing stone fire pits is essential for preserving their natural look and protecting against the elements.

  • Frequency: Once every 12 to 18 months, depending on your climate and usage
  • Product type: Use a breathable, stone-specific sealant (penetrating, not glossy)
  • Where to apply: Only on clean, dry stone; never seal over dirt or moisture

If you purchased your fire pit from Fire Pit Outfitter, ask our support team for sealant recommendations designed for your stone type.

Gas Fire Pit Maintenance: Protecting Your Burner and Ignition System

Proper gas fire pit maintenance helps avoid costly repairs and ensures safe operation.

Here’s how to protect the internals:

  • Let the fire pit fully cool before covering
  • Use a heavy-duty fire pit cover to protect against rain, snow, and UV damage
  • Wipe down the burner tray periodically to remove dust, leaves, or ash
  • Consider installing a tempered glass wind guard to minimize debris and protect the flame

What’s the Best Way to Winterize My Fire Pit?

Winterizing is essential if you live in a colder region or even if you just won’t be using your fire pit for a while. It ensures your setup stays clean, safe, and ready to go next season. This step alone can extend the life of your fire pit by several years.

Winterizing checklist:

  • Clean the fire pit thoroughly (follow steps above)
  • Remove and store loose components indoors (lava rock, logs, burner covers)
  • Cover the fire pit tightly and check periodically for moisture under the cover

Can I Leave My Fire Pit Outside Year-Round?

Yes, as long as it’s properly covered and cared for. Fire pits are built for outdoor use, but they still need protection from the elements.

Rain, snow, and UV rays can wear down even the most durable materials. Moisture buildup during freeze-thaw cycles can lead to cracking.

What to do:

  • Always use a snug-fitting, breathable cover
  • Elevate slightly if standing water pools nearby
  • Remove snow buildup to reduce weight and moisture

What Accessories Make Maintenance Easier?

Smart accessories do more than look good; they help protect your fire pit and extend its life.
