When you get a brand new drum smoker you need to season it, which is basically burning in some cooking oil. So what I like to do is pull up my oil spray and coat the entire inside of the drum with some cooking spray. 

It’s just regular old canola oil. Then fill it up with your favorite brand of charcoal and light it up with your chimney starter or gas burner, you can do it both ways. You can also throw a wax cube in there and light it that way but I really like doing it with my favorite fire starter.

Here’s the reason why you want to burn a drum in. It’s because it’s got the factory oil and just like a cast-iron skillet you have to season it before use.

And it’s a really simple process. It’s just about getting the metal nice and hot and just like pores on your skin the metal once it heats up it starts to expand and the pores if you will start opening up allowing the oil to get absorbed or get baked on.

That helps season the drum. Remember to also oil up the bottom side of your lid.

I don’t need to leave the vents open because my charcoal is already lit from the firestarter. That way I can go ahead and close this lid so I’m gonna put my grate in there right away and let that burn-in as well.

Don’t forget to spray the grate down with oil as well and you can go ahead and shut the intake valves or leave it a quarter of the way open I know that’ll usually gets me to about a 300 degrees which is where you want it for seasoning the metal.

There are a couple of products that I think are a must-have. I keep all of my drums clean, nice and shiny. I like to keep the external looking fresh and new and what I use is this McGuire’s quick detailer with just a rag and you only need to spray it on and wipe it down. 

If you try to do that after every time you grill you’ll keep the paint looking nice and neat.

One thing I also like to use is a multi-purpose absorbent.

Before grilling I’m going to dump probably a quarter of an inch of that oil absorbent at the bottom and the reason I do that is if you do have some grease that falls on the bottom you don’t want a grease fire.

Because obviously that’s going to burn your food and you don’t want that so I always pick up a big bag of absorbent.

You do have smaller bags but quite honestly you’re spending just a couple bucks more and that’ll last me a long time. Again, you just need a quarter of an inch or so on the bottom just to absorb any grease and to prevent any grease fires so that’s what I use as well.
