How to Clean a Gas Fire Pit: A Step-by-Step Guide

A gas fire pit is a low-maintenance alternative to traditional wood-burning fire pits, providing instant warmth and ambiance without the hassle of ashes or soot. However, regular cleaning is essential to keep it functioning safely and efficiently. 

Dirt, debris, and weather exposure can cause burner blockages, affect flame quality, and even lead to long-term damage. In this guide, we’ll walk you through the best practices for cleaning your gas fire pit, from routine maintenance to deep cleaning, so that you can enjoy a safe and beautiful flame all year round.

Why Regular Cleaning of the Fire Pit is Important

Maintaining a clean gas fire pit is about more than just aesthetics—it directly impacts performance and longevity. Here’s why you should clean your fire feature regularly:

• Ensures Proper Gas Flow – Dirt, soot, and debris can clog burner ports, leading to uneven flames or difficulty igniting.
• Prevents Corrosion and Rust – Exposure to moisture and outdoor elements can cause wear and tear over time.
• Enhances Safety – A buildup of grease, dust, or insects in gas lines or burners can become a fire hazard.
• Extends the Lifespan of Components – Routine maintenance reduces wear on ignition systems, burners, and decorative elements like fire glass or lava rocks.

For best results, a light cleaning should be done monthly, while a deep clean is recommended at least once per season or after heavy use.

Tools & Supplies Needed for Cleaning

Before you start cleaning your gas fire pit, gather the following supplies:

• Soft cloth or microfiber towel
• Mild dish soap and warm water
• Soft-bristle brush or old toothbrush
• Compressed air or a vacuum with a hose attachment
• Stainless steel cleaner (for metal fire pits)
• Non-abrasive sponge
• Fire glass/lava rock sieve or colander (for cleaning media)
• Protective gloves
• Dry towel for drying components

Avoid using harsh chemicals, abrasive pads, or power washers, as they can damage the fire pit’s finish or internal components.

Routine Cleaning: Quick Maintenance for Everyday Use

For regular upkeep, follow these simple steps:

1. Turn off and cool down – Ensure the gas supply is completely turned off and allow the fire pit to cool before cleaning.
2. Wipe down the exterior – Use a damp cloth and mild soap to remove dust, dirt, or water spots from the fire pit’s surface.
3. Inspect burner ports – Look for any obstructions or soot buildup in the burner holes. If needed, use a soft brush or compressed air to clear blockages.
4. Clean fire glass or lava rocks – Shake out debris using a colander and rinse with water if dirty. Let them dry completely before placing them back in the pit.
5. Check gas connections – Ensure hoses and fittings are secure and free of leaks before lighting the fire pit again.

Performing this routine maintenance every few weeks will keep your fire pit looking great and working correctly.

Deep Cleaning: Seasonal Maintenance

For a more thorough cleaning, follow these steps every few months or after heavy use.

Step 1: Turn Off Gas Supply and Disassemble Components

• Close the propane tank valve or shut off the natural gas line.
• Remove fire media (lava rocks, fire glass, or ceramic logs) and set them aside.

Step 2: Clean the Burner and Ignition System

• Use a vacuum or compressed air to remove dust, debris, and cobwebs from the burner and ignition area.
• If there’s a grease buildup, use a damp cloth with mild soap to clean the burner. Avoid soaking electrical components.
• Inspect the burner holes for clogs and clear any obstructions with a toothbrush or soft brush.

Step 3: Wash Fire Glass or Lava Rocks

• Place fire glass or lava rocks in a colander and rinse with warm water to remove dirt and soot.
• Let them air dry thoroughly before returning them to the fire pit.

Step 4: Clean the Fire Pit Exterior

• Use a specialized stainless steel cleaner to remove fingerprints and maintain shine for stainless steel fire pits.
• Scrub gently with mild soap and water for stone or concrete fire pits. Avoid pressure washing, as it can erode the surface.
• Use a non-abrasive sponge with mild soap to prevent scratching for painted or powder-coated metal fire pits.

Step 5: Reassemble and Test

• Once everything is dry, place the fire glass or lava rocks back into the burner pan.
• Check that all components are secure before turning the gas back on.
• Perform a test ignition to ensure everything is working correctly.

5. Preventative Maintenance Tips

Keep your fire pit in top shape with these simple precautions:

• Use a protective cover – Shield your fire pit from rain, dirt, and UV damage with a weatherproof cover.
• Store propane tanks safely – Keep propane tanks in a dry, ventilated space away from direct sunlight.
• Avoid spilling grease or liquids – If using your fire pit near an outdoor kitchen or dining area, prevent spills that can cause stains or damage.
• Perform seasonal inspections – Check hoses, fittings, and ignition systems periodically for signs of wear or leaks.

With proper care, your gas fire pit will provide years of warmth and enjoyment without frequent repairs or replacements.
