hi:
   i would like to make an acid bath to remove the rust from small parts.
the stuff you get with gas tank cleaning/sealing kits seems pretty
impressive. what is it ?  i figured that it must be phosphoric acid. ....
but a local chemist tells me that phosphoric acid has no odor . the tank
acid has a very distinct odor--much like prep-sol or navel jelly.   i will
need a fairly large batch to  make the vat useful, probably about 4 gallons
(diluted ?). 

 thanks,  fred zampa
