How do I clean fire glass in a gas fire pit?
With the gas off and the glass fully cool, scoop it out, rinse it in a bucket of warm water with a little mild dish soap, swish to loosen soot and dust, then spread it on a towel to dry completely before it goes back in. Never return wet fire glass over a burner — trapped water can flash to steam. Skip harsh chemicals and abrasive pads.
Why it goes dull
Fire glass loses its sparkle from three things: soot if the flame's ever run rich, everyday dust and pollen (and WNC lays down plenty of both in spring), and a mineral film left behind when rainwater dries on it. None of that means the glass is bad — it just means it's due for a wash.
The wash, start to finish
Turn the gas off and let everything cool. Scoop the glass into a bucket or a colander, run warm water with a squirt of mild dish soap, and swish it around to lift the grime. Rinse until the water runs clear.
Then dry it thoroughly — spread it on a towel in the sun if you can, and be patient. This is the step people rush, and it's the one that matters most: any water still trapped in the pieces can turn to steam over the burner. Once it's bone-dry, spread it back evenly and don't bury the burner ports.
When cleaning isn't enough
If pieces come up cloudy, etched, chipped, or permanently soot-black after a good wash, the glass is spent and it's time for fresh media. We can point you to the right glass or rock for your burner so you don't overfill it or choke the ports. Questions on media or a burner that's sooting the glass? Call (828) 545-0525.
