How do you arrange glass in a fire pit?

Evenly disperse the fire glass across the burner area and make sure to not overfill the burner area with glass as the gas supply needs air circulation in order to produce a flame. If you have so much glass, that your flame is muddled or its blocking the gas output, immediately shut off the fire and remove some fire glass.

How to Clean Fire Glass?

Proper cleaning and maintenance of your fire glass will help keep it looking its best. Here's a step-by-step guide to help you through the process:

Supplies You'll Need:

  • A bucket
  • 1 gallon of water
  • 1 gallon of household vinegar
  • Plastic scoop for removing glass from your fire pit or fireplace
  • Large wire mesh strainer (such as those used in the kitchen to drain pasta)
  • Tarp or plastic trash bag
  • Supplies for cleaning your fire glass


  1. In a bucket, create a mixture of equal parts water and vinegar.
  2. Use the plastic scoop to remove the dirty fire glass from your fire pit, focusing on the top layer and areas around the edges or near the burner.
  3. Add the dirty fire glass to the bucket of water and vinegar solution.
  4. Stir the fire glass in the solution using the scoop, ensuring thorough cleaning.
  5. Remove the fire glass from the water/vinegar solution and place it in the wire mesh strainer.
  6. Rinse the fire glass with clean water, using a garden hose for convenience.
  7. If you are using tempered fire glass, it is recommended to dry it completely before using it again. Spread the glass out on a plastic bag or tarp in a sunny area, or leave it overnight in a non-sunny or indoor location.
  8. Once dry, your fire glass is ready to be used again, providing a beautiful and safe fire feature.

Properly maintaining your fire glass will ensure its longevity and keep it looking vibrant for many enjoyable fires to come.
