Removing Rust with Citric Acid

[SuperNovaSS]

Thanks John,


I have seen it as drain cleaner at stores. What is the approximate ratio you use? What precautions do you use? I love the term "metal laundry" by the way.


Thanks,

Jason

Usually I mix a two pound container to 10 gallons of water. If you mix it weaker, it just takes longer. Always add the lye to the water, never pour water into lye crystals. Just like with your acid dip, it is necessary to hose off the slime, and then I blow the part dry to keep it from rusting. If you are going directly to the acid dip, all that is needed to spray off any paint, grease or lye residue.

This stuff is hard on skin, so be careful not to get it on skin or in eyes.
