using an old alcohol tank (100gallon) for a mixing tank.

[Dinnin]

Starting work on a very large mixing station, and got offered a tank that has had isopropyl alcohol in it for shipping, and is being sold as food grade.

I can't see any issues in using this as a holding tank for ro and or saltwater mixing....unless I'm missing something?

I see no problems if it's food grade.

My 55g mixing barrel had photographic developer or fixer in it. (can't remember which) I washed it well and put it to use. Almost 30 years ago. I'd rinse it and go for it.
