I burn BB store pellets and when I do a clean out I have resorted to using a 5-1 tool to scrape the clinkers out of my Burn Pot Liner. This has served me well for years but sometimes its a real PITA to get the really baked on stuff to come off. For the real stubborn stuff I have tried soaking the liner in solvent, ran it thru my ultrasound tank, and even the "blowtorch" method. All of these failed. Now I have found a fantastic method that gets about 95% of the clinkers. This is after the clean out. Sorry I didn't get a before picture. I know it still looks dirty, but believe me, the clinkers are gone. So what is the new clinker tool It makes quick work of the clinkers. Does a real great job. Wear hearing protection as it is loud. I bought it for cleaning up my welding. This a small needle scaler about 12" long. I have had great service from every Astro tool I own and they are usually well priced. This one is currently $87.00 on the big A. Hope this helps ---Nailer---
IIRC Oven cleaner is Lye and a few other solvents based. It is an excellent grease remover it might loosen the carbon as well. I have not tried it but have tried MEK, Acetone, Berrymans B-12 (Carb Cleaner), Simple Green, Plain Water, and Denatured Alcohol. None of them worked well. The Needle gun does a great job of breaking up the hard deposits. If I get really tempted I may throw the burn pot liner into my electrolysis tank and see if that gets everything off. I don't think a BP liner needs to be spotless for use so that may be way overkill. lol. ---Nailer---
I have one that I use on my stove refurbs and they work great! Does an amazing job on the Quad burnpots.
Now we need a portable battery power one! I tried it at the shop, We used pen power which was used for cleaning molds. It did OK, But still needed to beat the tar out of the carbone to get it off. Did a nice job on it for weld prep though.
Yessssssss indeed....A rattler...I used to work in a welding and fab shop...Before we all went to wire feed welders and ran stick....Every work station had one of those...We called them "Rattlers" They really go after slag and other crud really well..... Sand blaster works good too... Good deal....Glad you found a tool the works well....
Hello Some people use oven cleaner for getting the stained areas of the fire door glass clean and it does work! Like Snowy said, I use white aluminum oxide in a blasting cabinet I picked up with a good model Quincy and their chiller for good dry air. Trinity Trinco Model 24 Trinco 24 x 18 x 23" Working Dimensions Free-Standing Pressure Sandblaster 16 CFM @ 80 psi, 26" Overall Cabinet Width x 62" Overall Cabinet Height x 18" Max Cabinet Depth, Steel, Dust Collector 10000240 - 82944042 Since the Harman Burn Pot does not remove easily, I installed a compressor air drop near it and use the Harbor Freight Air Scraper for cleaning the old Harman black carbon speed bump. The HF Air Scraper Kit Only $29.99 you cannot go wrong! Works amazingly well! https://www.harborfreight.com/air-t...pers/6-piece-pneumatic-scraper-kit-95826.html I also use an air gun on the air drop to blow out the air wash slot to keep the fire door glass nice and clean.
I have that same needle scaler, it rips! Great for rusty old trucks. Is your burn pot easily removeable? Once a year I put mine in the media blast cabinet and take it down to bare metal. Every two or three years I have to weld some more metal on to it and drill new air holes.
The burn pot liner on a M-55 is easily removable. I have an OEM set and an Aftermarket set. I am getting ready to weld up the OEM set. I don't have a blast cabinet but just changed jobs and the new place has a nice one. I see some afterhours work in my future. lol ---Nailer---
