The juice plant I worked at we had some welds in our piping that started to rust. We found out we had bad filler rod. I really don't think it was the vinegar that caused it.

usually stainless only rusts if its low grade stainless or if carbon is introduced to the weld , via bad filler wire ,or using wire brushes or wheels that have ground steel. stainless carries some pretty bad stuff and is fine . find it hard to believe vinager is worse than the stuff that gets run in paper mills and chemical plants

Acetic acid (vinegar) can severely damage 304 stainless. It has only minor effects on 316 stainless.

It seems that according to the table the severe effects occur at extremely high acid concentrations. The stuff we use as regular consumers is very low concentration (I believe 5%). However, time and high temperature would likely enhance those effects.Originally Posted by DrTimPerkins

Evaporation of the water will concentrate the acid.
And time will make it worse. There are pinholes, or just surface rust? What do you burn in the evaporator? How do you clean the underside of the pan? How was the pan stored over the off-season?

I would bet my money on a bad weld, I can’t tell exactly by the picture but that seams most likely. If they don’t make the situation better I would sell it as soon as season is over and just get a SL since it will always have a lifetime warranty and his stuff is better welded than anything else I have seen out there.

Does this mean that those of us who use vinegar to clean our pans are taking a significant risk or is this situation unique?

Ther is insufficient information at this point to determine the exact cause(s) of this problem.
