Black residue when cooking with propane?

Question

My indoor range (and oven) use propane, but it always leaves a black film on all of my pots and pans. What is causing this and how can I fix it? We don't ever have problems with pans in the oven, but the grills in the oven end up covered with the black film as well. If you need more details, ask. Any advice would be much appreciated.

Answer 1

Sounds like the air to the burners needs to be adjusted. If it is getting too little air it will not burn clean.

Answer 2

Gas pressure may be too high, but most likely the air mixture on the burners needs to be adjusted.
