Rust Removal

Convert the rust (iron oxide) to iron tannate by wetting the rusted surface down with tannic acid. The the surface will turn black. If it doesn't, then the surface wasn't rusted or the rust was not treated sufficiently. Tea has tannic acid and is the reason why you shouldn't drink tea with meals. It will convert the iron compounds to iron tannate and may result in being anemic.
