I assume you can turn on the pot and melt the solder, then scoop both the molten solder and the crud out, scrape it clean, fill it with fresh solder and send it out for analysis, if it passes continue production, update the maintenance schedule, and go from there.

Subject: [TN] grunge at bottom of tinning solder pot

I have two wire tinning solder pots that have not received the proper day-to-day maintenance and now there is solid crud filling all but about ¼ of the crucible.  I have tried chiseling it out and drilling it out.  All I end up with is dull tools, even carbide drills.

Other than buying new solder pots or replacing the crucibles are there any suggestions for removing this super hard stuff?
