Re: Removing Rust.
Oxalic acid is safe and very effective for removing rust. Some pharmacies carry it. The next best product for actual iron rust removal is Super Iron Out, sold in places like WalMart. When I retreat to the farm house I have to add that to wash clothes, toilet bowl & tank, tub, wherever that iron rich water goes.
