Furnace cleanup

[Echo]

I have this old Potter 3-lb furnace I used to use for small jobs. No control, I ran it through a Router Control from Harbor Freight. Haven't used it in years, and decided to fire it up, and it heats. But it is really dirty inside, with some little trash & stuff (been sitting out on the covered patio). Would it be OK to put a couple drops of soap in it, mostly fill it with water, sit it in the sink, turn it on, and boil the crud out? I would maintain a reasonable watch on it so it doesn't boil dry...

I just hit mine with a Dremel with a little wire brush to take off the heavy funk when I first got it, but normally it stay full of lead so not much clean up is required. Oddly enough it is my best pot for pressure casting.

I'd just put some alloy in there and flux, scrap, scoop ...flux, scrap, scoop ...flux, scrap, scoop.

Check out this thread. I did it to a Seaco pot recently and it worked great.

Wow, Minerat, that works GREAT! But. I decided just do a little disassembly, clean 8up the externals, and add alloy, flux, scoop, as JonB suggested. Will publish after completion. Here it is as before - note added stop...

Mine wasn't quite that bad as I had been using it. I did what JonB suggested before I drained it and then gave it the Hydrogen Peroxide treatment. It did not look like the RCBS pot shown in the post, but it really cleaned scale off the rough iron guts in the Seaco. Good luck.
