Thanks for the Ideas! I especially like option 3. I don't think I'd ever try option 2 as I don't ever want to introduce any lighter fluid smell to the lava rocks. If option 3 doesn't work I think new rocks are in order!
Electric Smoker
I have a Model 810-7090-S They sell at Home Depot for about $70. I got mine a few years back for about $50 -$60. I does have something akin to Lava rock in the base (below the element).
Lava Rocks in a Smoker
I too have a Brinkman (electric) smoker. The lava rocks that set below the element are getting gummy because of the fats that drip off the meat. Is it necessary to replace them periodically or is there a way to renew it?
