[AT] Phosporic acid - where to find it?

[Larry D. Goss]

You could probably use Rustbeeter (www.rustbeeter.com) to clean the tank
or go down to your favorite ag supply store and buy a bag of beet
molasses (horse food supplement) and mix up a brew in your kids wading
pool to soak it in.  The ratio is supposed to be around 18 pounds to 55
gallons of water.

>From what I've read and heard about this concoction, it won't remove
paint (unless it's blistered), but will remove both the black and brown
iron oxide.  The process takes several days, but is very environmentally
friendly.  As I understand it, beet molasses is a by-product of sugar
beet processing and it contains the chemicals that allow the beets to
absorb iron out of the ground.

Most likely what you are looking for is under the brand name "Ospho".
It is made to be painted on, but you could just pour it in, roll the
tank 
around to insure complete coverage and drain the excess. It is
recommended 
that the excessive, loose rust be removed first, but you've probably
already 
done that.

>Hey all - I've got a rusty gas tank I'm cleaning out.  I want to use 
phosphoric acid so I don't have to use a sealer once the tank is
cleaned.  
But doggone if I can find anybody that carries this stuff.  I called a
couple 
lumber yards, Menards, Fleet Farm, and Sherwin Williams - everybody has 
Muriatic acid, but no phosphoric acid.

I'm told Sherwin Williams carries this product...can anybody give me a
brand 
name or some sort of product name to identify the stuff rather than 
just "phosphoric acid?"  I don't think most people I'm talking even knew
such 
a thing existed.  I figure a brand name will help out.

Thanks,
