I'm not too particular usually but have been considering getting a poker and digging out some of that gooey funk.
How about you?

I leave it alone. I think it forms a new raised bottom for the pipe which will prevent the bottom from burning out. Cobs are all I smoke these days and it's never given me any problem. The low maintenance is one of the things I love about them.
