Black grease spots on beer can burgers in PBC

[qposner]

A while back I made 6 good sized beer can burgers on my PBC. Sadly, they ended up with black grease on them. I assume from the fat dripping and vaporizing. Obviously not very appetizing. Anyhow, making a few tonight and would live to avoid this problem. May just cook them indirect in the kettle. Anyone know how to avoid that on the PBC? I used 80/20 ground beef. Thanks!

The only time I’ve had that issue is after long periods of no use and/or high humidity.

Just gotta burn it out and get rid of the excess moisture in the PBC.
