Duct Seal Solvent?

Yeah, I suppose that's not bad. But, I feel like if I'm digging lead outta duct seal, chances are that would take most/all of the savings outta the process. :)

(LOL, and ALL of the fun and danger of doing stupid stuff!)

IDK should get a bunch of tins out if it if you let it drip for a while, of course Acetone is way cheaper, or at least it was. I'd find a different way to trap the pellets. Like Rubber Mulch and Carpet to hold it in place.

Smoking duct seal goop and tape may actually be significantly worse than the solvent fumes.. LOL.

This entire thread is sketchy to some degree. :)

Way back in the old days, I had to go into a block house with 55gal drums of Acetone, to clean molds, let's just say that ventilation was minimal, still here 52 years later. It did suck, thusly the well ventilated area.

Acetone will break it down, remember, no open flame, use in a well ventilated space. You MIGHT try a little ultrasonic cleaner, might speed up the process. No need to dump your acetone until it gets really nasty.

Got a small sample in a covered dish of acetone in the basement tonight. No joy with the denatured alcohol test.

Something else that will work is that orange oil cleaner, you can safely heat it up and no chance of a painful encounter in the ER. Breaks down the adhesive, rinse in soapy water then clear water. If you are on the West Coast just put them outside, rinsed in 3 minutes.

What is the brand name of that orange oil cleaner? Will try it if it's not too much $$

Many of the solvents that have been mentioned are definitely not something that you want to be breathing in. In very small quantities they are generally not too bad, but in the quantities needed for the intended purpose a respirator would likely be needed and done outdoors.

It seems to me that the using a two-pot system for melting the lead down might be the easiest. The first pot would be to get the majority of the junk out and then a second melt, in your regular pot to finish the job. I can only imagine that the duct seal would rise to the top once the lead melted. I bet you could get an appropriate pot for cheap at good-will or someplace like that.

Would consider that. I really DON'T want to put that gunk in my PB boolit casting pot. We were melting 300 lbs of lead once to make cannon projectiles and threw in a bunch of old roof flashing covered with tar. The tar caught fire and burned for over an hour. When done there was a layer of ash on the top BUT there was black stain all over the smelting chamber.

wheel weights are dirty , decades ago I used to melt in 100 pound pots with propane any garbage will float to surface just ladle off and melt into a cube then throw cubes in lee melting pot ,

Me being a mechanic I used to pour my ingots into a old bmw medal hub cap perfect size to fit into Lee pot , I feel washing is waste of time espially with cleaners mentioned cost more then pellets lol

Melted hundred of pounds of those over the years. The old school ones had a metal clip only that floated right on top. The ones with rubber make an ungodly mess in the pot. Heat treated wheels weight metal is the same as Lyman #2 alloy.

Those days are far behind me. I do try to keep the stupid stuff to an absolute minimum.

If all else fails try MEK. Get it at the paint stores. Stuff will melt PVC and ABS pipe

Fun stuff, totally awesome to light it on fire and play in the flames. (They're super cold flames, takes forever to burn you)

The issue with the more volatile solvents is their tendency to evaporate quickly. If I was using them, I'd either seal it in a can, or add something less volatile to keep it from evaporating as quickly.
