Its time. I've had the OKJ now for about 2 years and I've noticed a creosote build up on the dome in the smoking chamber.I also noticed a build up of grease on the heat baffle as well so I think its time to give the Longhorn a good bath. I'll be using a 2800psi power washer and the most gentle nozzle along with plain soap. I was thinking about using Dawn as it does cut grease very well. Mix in some GOOP perhaps... Since tomorrow weather wise looks reasonably warm, the plan is to remove all the grates and plate, then power wash both the cooking chamber and the dome. Leave it open to air dry, then go over it with Olive Oil before covering. Has anyone else done anything similar? I plan to power wash the heat baffle and the grates as well. Might as well start the 2015 smoking season right..
