Cleaning OWB

[Steve_M]

I have been running an Empyre 450 for the past 4 years ---365/year.  This past year I have felt that the OWB has last some of its efficency--not that it has a lot to start with.

I recently shut it down for the summer and would like to take the opprotunity to give the fire box a good cleaning.  I have done some cleaning before with scrappers, chisles, screwdrivers, ect.

Has anyone used any type of spray on cleaner with any success to get the fire box to a "like new" condition?

Should a just knock of the chuncks and not worry about the rest?

Anything a hot fire won't take care of?

on my Hicks, just open it up and let it run, might even hear the water boiling, after a little while run the brush through the tubes and it is clean.

I agree.  Get a good hot fire and a long handled scraper.  It won't get so clean that you'd eat off it, but it removes the vast majority of the build-up.
