<VV> Muriatic Acid Vs. Phosphoric Acid

[Harry Yarnell]

I've used muriatic acid diluted 50% with water.
It won't remove grease or oil, but WILL remove rust. If left unattended, it
will continue to eat the steel. Nasty stuff, so be careful.
Wash with water, but treat it as soon as it dries, as what you just
de-rusted, will start rusting immediately'
Purchase at building supply stores, as it's used to wash brick walls.

I have read about both of these acids in the Corvair tech guide, does anyone
have any experience with either one of these. 
 
I want to clean up some half-shafts and suspension parts. Is Phosphoric acid
easily found , if so where? Which one seems to work better? 
 
What's the mix ratio of water to acid on the Muriatic acid. Once dipped in
the Muriatic acid, what additoinal prep is needed other than washing them
off prior to painting. 
 
Thanks.
