ORIGINAL: Aneirin Yeah, I have borax too, but it gets used as a flux for soldering. One of the problems I have discovered in using old substances, is sourcing them. Castille soap, though I know of it's uses in other things, I can't find it in my town, Glycerin, the same, I can't find it, ask a shop assistant, they don't even know what it is. I had even to give reasons why I wanted borax when I got it from the pharmacy, as they would not supply it otherwise. Me thinking here, all these basic substances that were around at one time, might now be restricted, due to what other things can be made out of recipes of basic substances, a product of our present age no doubt. Nitric acid, now, that is impossible to get hold off locally, even the horticultural suppliers get iffy when one asks for pH down, no, I don't want the one with phosphorous in it, I want the nitric acid variant, (about 38% pure) Phosphoric acid won't take the pH down as low as nitric acid does, but it actually has some advantages. Besides the acidity, the phosphate anion will chelate iron and other metals, which make it a better rust remover. Oxalic acid, which is sold under various brand names, is even better as a rust remover. Muriatic acid should be pretty readily available. It's widely used for cleaning concrete. I can't think why you'd want nitric acid anyway for cleaning. It's an oxidizing acid, which makes it better for solubilizing some things, but that shouldn't matter for general cleaning. And its fumes are likely to turn your fingers brown.
