You are more right than you probably realize

Since I obviously didn't want to start with all that in there, I took a wire wheel on my hand drill and cleaned it out. Since the pot liner is stainless steel on the RCBS, I got it all out.
SAFETY NOTE: Airborne lead dust is not good for you...wear a respirator!!!
It took about 10 minutes, but I got the pot back down to shiny. I blew it out with compressed air outside, cleaned the nozzle and put it back together. I loaded it up with some fresh Lyman #2 and commenced casting.
I was blown away with the quality of the boolits. A picture is attached. I reasoned that the residue from that Marvellux was coating the sides of the pot. When I would stir the pot, bits of it would break off and contaminate the melt with that stuff. Somehow, as is mentioned above, it would get into the spout and into the boolits. Pete
Mr Zbench sir, I couldn't agree with you more. Several years ago I literally threw a full can of Marvelux in the trash. I wouldn't allow that horrid stuff anywhere near my loading/casting room.
Like you I had to use a stiff wire wheel on the drill motor with considerable time and effort to try and clean it off. That was with the RCBS pot which is now clean and completely free of that disgusting white powder. Since I got the Magma 40 pound pot a few years ago it has seen NOTHING but saw dust and the inside is spotless to this day and so are my boolits.
It's not uncommon for me to be asked how my boolits look so good and the answer is very simple, clean alloy, clean pot. So why is my alloy and pot so clean? Simple, very, very simple. Sawdust. No Marvacrap, no wax, no oil. IMHO wax's and oils are only slightly better than Marvacrap, they gunk up the inside of the pot and most wax's and oils stink something horrible.
Flux is like boolit lube, when someone has their favorite there is no talking to them about it, their way is best and that's that. Ok, fine. Let them scratch their heads trying to figure out why they have inclusions in their boolits.
