Brown residue in firebox help

[clbraddock]

Hi, 

I have recently been using a Yoder offset smoker. I have developed an issue with residue in the firebox. The interior of the firebox has a normal black color, but when I try to wipe it down I get smears of a brown residue that wasn't visible prior to wiping. This problem is only in the firebox - the cooking chamber is seasoned and has not has any issues. Im thinking it is possibly creosote, but am unsure. Is there a good way to remove this? Water somewhat works, but I am reluctant to wet down the firebox due to rust concerns. Any help would be appreciated.

Thanks!

Chris

No worries in firebox...it is normal it is from combustion process.

Let that stuff build up. It will eventually start to peel and fall down into the fire. Who in the heck cleans the firebox?

Hello.... OCD. Hahaha....

Yeah, I might just be being to ocd about it. The smoker was really expensive for my budget so Im just paranoid to make sure I'm taking care of it properly. 

If you guys don't think it is an issue, I won't worry about it.

Thanks,
