Molasses also works very well as a stripper/derusting agent. Takes a bit of time though. https://youtu.be/mzoQj91glP4 https://youtu.be/h7EOw5Thuo0 https://www.christinedemerchant.com/molasses-rust-removal.html Rick ___ http://www.okiebenz.com To search

Not in itself but your ability to mix to the strength you want is a big advantage in vinegar. Got something heavily rusted? Add a bunch of crystals. Something delicate? Use fewer. Its cheaper (5# for $20 delivered from Amazon has lasted me 8 years.) and doesn't smell as strongly. Mixed strong

You can easily make it stronger, whereas vinegar can only easily be made weaker. On Tue, Jun 23, 2020 at 7:09 AM Dimitri Seretakis via Mercedes < mercedes@okiebenz.com> wrote: > Is citric acid more effective than vinegar? > > Sent from my iPhone > > > On Jun 23, 2020, at 7:55 AM, Curt Raymond

For something that size an overnight soak in citric acid will do a really good job, scrape it with a wire brush ever couple hours for maximum rust removal.Once the rust is gone a couple hours of naval jelly adds the phosphor that helps key the paint. You could use evaporust (or other similar)

Yeah that does work like magic. Just be sure you get the positve and negative connected the right way, if you aren't sure about the chemistry or what "anode" means. Postive goes to the sacrificial iron, and negative goes to the part you want to de-rust. A good (old) web page about it:

For something like that where you can tank it, using a battery charger and a bit of scrap iron to electrically convert the rust back to iron is cheap, easy, and highly effective! Plastic tank, water, a bit of electrolyte (any acid, or base, or salt) plus sacrificial anode and the battery charger
