I clean my racks too. With the Masterbuilt XL, I thought I cut a fat hog in the a$$ with the chrome racks. Just put them in the dishwasher, right? Wrong!! They're about 1" too long to fit, AARGH. But I found a plastic Mortar mixing tub at Home Depot that work perfect for under $10. Pam on the racks before the smoke makes the gunk come off easy.
There is nothing worse that trying to clean my grates on my MES. I tried in the sink with soap and water, and that was not working. So I fired up the Weber propane grill and place all the grills on there for a few minutes on high and everything burned off. Ran a brush over them and were nice and clean. Never going to waste an hour of my life and scub these things again.
Clean?? You Mean we are suppose to Clean Em? OMG Man Epic fail lol , Naw I usually Just Knock Off the big stuff and Move On I wipe grates with Oil or spray with Pam . I'm old school I Like the Taste of a Seasoned cook ( I don't smoke fish ) so It works well. But I will take it to a Car wash and hose every so often to do a once over, Lining the bottom with a drip pan or foil keeps the Greasiness down to a Minimum. and If The Racks do get funky I use a brass brush on a grinder and Bam clean in 2.5 rinse then oil. But I never Use soap, I dont like the taste if you miss rinse it
