There's also the slow, low-tech approach to rust removal. grin

It looks like this: [Linked Image]

And it does smell about the way it looks! Definitely outdoor use only.

What this is, is a bath made up from stock feed grade Black Molasses and water. I've seen mix ratios from 1+5 to 1+10 molasses/water recommended, but this 1+10 one is working just fine for me. Made up by weighing the molasses into the plastic bath [a cut-down 25L polycube], then adding a bucketful of hot water, stirring, and topping up from the garden hose.

I cover it with an old washing machine cabinet panel, to keep insects etc. out [and spray around it with Surface Insect Spray for ants].

One of the main advantages of this method is that it will only remove rust, and won't corrode good metal, if the workpiece is left in a bit longer than optimal.

It does take a while; up to a few weeks, for heavily rusted bits. Those will also require periodical removal from the bath, and scrubbing off the loosened rust with a nylon brush, a few times.
