I was at my friends getting ready for a BBQ, and he asks me how to clean a BBQ Smoker.
To clean a BBQ Smoker, start by removing the ashes from the fire pit, and get a big bucket of soapy water. Brush the grates, remove them, and remove any other removable components of the BBQ smoker and put them into the bucket. Scrape any gunk or build-up on the inside and vacuum it out. Wash and scrub the smoke, then spray it down, allow everything to dry, and reinstall any components and the grates. Re-season the smoker and is ready to use.
Why Do I Need to Clean a BBQ Smoker?
A smoker is slightly different than a standard BBQ grill because it cooks meats over multiple hours, allowing the flavor to seep in so that it is tender and delicious in the end. Some foods have to smoke for up to 24 hours to achieve the right taste, and that means your smoker is working that whole time. It’s not too complicated if you were wondering how to clean a BBQ smoker. All you need to do is follow a few simple directions, and your smoker can look good as new in no time.

Different Types of Cleaning
Your Annual Deep CleaningScrape and Remove
Just how should you get started with your once- or twice-a-year cleaning? Ideally, you should put a tarp down underneath the smoker and put gloves on because this is a messy job! Get a big bucket, put water and dish soap in it, and then set it aside for now. Then, brush your grates with a grill brush. If the BBQ grates are porcelain, be sure to use a brush with brass bristles, so you don’t nick or scratch them. Place the BBQ grates in the water bucket to let them soak for a while.
If your smoker has a heat diffuser plate, scrape and brush that as well, then unscrew the dome from the chimney and place both the dome and the diffuser plate in the bucket. Clean the inside of the smoke chimney with a wooden stick of some type or even a stiff brush. The interior of the chimney must be extra clean since this is where smoke build-up can occur.

Scrape and Remove
Grab a paint scraper and scrape both the cooking chamber and the inside lid of the firebox. Check the bottom of the cooking chamber to make sure that you get any dried food or grease out of the smoker. Use paper towels to wipe up the mess and make sure that you don’t miss anything. You can clean the grease gutter with the same wooden stick used earlier, and you can take a wet/dry vacuum to scoop up any loose debris.

At this point, you can clean out drippings from the grease catcher after removing it. Go ahead and put that into the bucket as well. Then use a hose to thoroughly clean your smoker, including the cook chamber, firebox, and the exterior surfaces. If you have a pressure washer, now is the time to use it. You can use a degreaser to remove any stubborn dried-on messes. Make sure that you wipe off the gasket as well.

Finishing the Job
A Few Tips That May Help
If you need additional tips to make cleaning your smoker a little easier, here they are:
- The outside of your smoker should not be forgotten. You can clean it by using a towel and some hot soapy water every month or so.
- Since the hot plates can get food stuck on them rather quickly, you can crumple up an old newspaper to clean them, and does a great job of cleaning the smoker without scratching it.
- Your drip tray is one of the messiest parts, and clean it after every four or five uses.
- Avoid using Wire grill brushes because they can break off and get stuck to the food, increasing the odds that you’ll swallow the pieces, and this can be dangerous. If you refuse to give up your wire brush, make sure that you replace it every season because the older ones tend to break more often.
Regular cleaning can increase your grill’s lifespan, not to mention allowing it to work more efficiently and making your food taste better. A little bit of cleaning after each use and a deep clean at least once a year goes a long way in ensuring that your BBQ smoker works better and lasts for you to use year after year.
