I prefer the term "Aggressive Re-Cycler"
I've recently restored this BBQ grill that I resurrected from the curb.

It was a 2 year old Stainless Steel Kenmore 4 burner w/side burner, electronic ignition and a timer.....with a full bottle of Propane!
It was thrown away because it was dirty

How I maintain my Grill.
After using the grill I leave it on for a while to totally burn any residual grease/food. Then I wire brush it every time.
In summer, every 2-3 weeks, depending on use I remove the burners, scrape the Flame shields, run the Grates through the Dish washer and blow out the lower area.
What do you do to maintain your BBQ Grill?
Happy Trails
