Help please.

After looking at the ports of the torch this evening I'm a little concerned.
I use to have the ports nice and brass. Now it is black or soot color. What is happening to the torch.

Let me know what to do please.

Found out. Read on Arrowsprings dite. Dirty propane and or clean torch head along with the out side if the torch head. Go figure.
