When I worked at the solder factory they used a water soluble grease to lubricate the wire as it was going though the sizing dies. It was some rendered animal product. It was a secret formula, so it had a cryptic name like 'J15.' That wasn't cool enough so most folks nicknamed "bear grease."
The problem with bear grease was that it volatilized and got into the air. It ended up coating EVERYTHING, including the innards of the computer gear. It produced a black tarry coating that nothing, including TSP would cut easily. It undoubtedly ended up in folks' lungs. I had a whole slhs after working there.ew of health problems that magically cleared up about 6 months.
Just be real careful with bacon grease (or bear grease) as a flux.
