What is this

[outback32]

I've got my amnps to work twice in my mes 30. But both times I'm left with a thick brown stuff on the glass and in my mailbox.

I never had this when I used chips in the chip tray

Smoke residue.  It'll happen with any type of chips, pellets, or chunks.  The chips don't put out as much smoke, so you may not have noticed it before.

No harm from it.  The entire interior of ALL of my pits have a nice coating of it.

Ok thank you I have a uds I built and never noticed it there. I guess it just shows well on glass

It shows VERY well on glass.  Clean your glass after each use, because once this stuff gets thick, it's almost impossible to get off.

Look on the sides of the UDS, I'll bet you have it there as well.  You'll also notice it on your chrome grates.
