    These have been used before for rust treatment of tins, but I used them consecutively (12 hours for each), and I am very pleased with the results.

    It could be dangerous to mix them together, but they work great one after the other with a cold water wash in between.

    That’s a fine result. I’ve used the Hammerite for that task but not phosphoric acid too. I’ve supposed that that’s what the Hammerite mostly consists of, though I’ve not checked the label.

    Nice result.there @Twoberth. I have the Hammerite, but yet to actually find a phosphoric source. I think I looked a while ago but can't remember the link now. I've several waiting patiently for me to get my act together.

    coke for phosphoric acid, the cheaper stuff is fine

    coke was used to clean out clutches in rally cars so it must be good for you...

    Cheers @ally, I'm off to check the large stack of Diet Cokes we have. Thought it might be a little too agressive for just rust conversion purposes and I'm not sure if anyone has mixed wallpaper paste with it either.
