Oxalic Acid + water = Crazy easy rust removal! No scrubbing @ all,
just mix and let soak!

Dan Gorsline.



Oxalic Acid has historically been used for years by radiator shops and machine shops for boiling engine blocks.  It's also been used in toilet bowl cleaner and other such cleaning agents.  It occurs naturally in a lot of plants, such as rhubarb. My neighbor lost a bunch of sheep when they ate up his wife's rhubarb patch. Oxalic acid has needle-like crystals which are a severe irritant to the digestive tract.  if you insist on ingesting your rust remover use citric acid instead.  I've used citric acid for years and recently purchased a 25 pound bag of the stuff. Recently took a 5 gallon bucket full of a rusty nuts and bolts and soaked in a solution containing about a fourth of a cup of citric acid, let the bucket sit in the hot sun for two or three days,  rinse them off and they look like new. I demo it's safety features to friends by licking the stuff out of my hand.
