Thread: Rust converter

Tweet

This topic seems to come up every year at least once, so you could do a search and read lots of responses from the past.

In the short run products like Rust Mort, Naval Jelly, and hosts of others, including etch primer, contain phosphoic acid. The acid attacks the rust and converts it to iron phosphate. Very effective for arresting rust. The frame pictured below was scuffed to knock off any loose rust particles then washed down with phosphoric acid solution (I bought a gallon of it 20 years ago and make my own solution with water, still have a good part of the bottle). Though the frame looks "clean" there probably is some microscopic rust formed(ing), so it will get washed down again before priming. This is in my garage near Seattle, so it's not like I have dry air to help keep it from forming rust. Hand prints will accelerate the rate of corrosion, even when treated.

Here's a link to one thread you'd find in a search"\: http://clubhotrod.com/forums/showthr...t=rust+removal

Edit: I should go without saying, but then again.............whenever handling acid you should make sure you use chemical resistant gloves, eye protection, and be in a well ventilated area. Keep a box of baking soda handy too to neutralize any spillage.
