To remove rust I usually use a wire wheel in a drill or the wire wheel on my bench grinder. Then a couple of coates of Metalmorphosis https://www.ebay.co.uk/sch/i.html?_nkw= ... b63ec286c7 followed by paint of your choice.

Pete, you can use solvent that's of the type that evaporates easily (which is what I believe you are thinking of) or you could use a water-based cleaning solution which works quite well. For the latter, it's like using Gunk, but having several chances without the need to keep rinsing. A nylon bristled-plastic brush is also a good idea because at times the mechanical action of thee brush is much better than the fluid "jet" (it's not really a forceful jet) or the gentle detergent action on their own.

I followed various tests on YouTube and Evapo-Rust came out tops in all the tests.

Water, bicarbonate soda, wires and small plates and an old style battery charger. Loads of demos on utube. No fumes.

I should clarify, my recommendation is for grease removal, looks like the others have covered rust removal.

For rust removal - what Bash said - using electrolysis - the easiest way and it only removes the rust. Takes a bit of setting up, but easy after that.

When I did my engine rebuild I just used petrol and an old toothbrush for grease removal. Grates to spend that much tax on a cleaning liquid, but it was still cheaper than Gunk! Maybe not with the price of petrol this week... :roll:

Why are you all faffing about removing rust ? There is a special paint called Hammerite. All you have to do is paint it straight onto any rush after tickling it with a wire brush and all your problems are solved ! :lol: :lol: :lol:

To think I used to spend my hard earned on that rubbish as a lad. I don't know how they get away with selling it

To remove rust on smallish parts I've been using the old bath of vinegar ploy

Electrolysis guys - do you get any deposits on parts after the rust has gone? I currently use citric acid (+ surfactant) bath but after the rust has gone you get a dark grey deposit witch needs wire brushing off - lots of work. If electrolysis leaves a cleaner finish I'll defo try it (now most of my parts are done!! :roll:

Hi Pete, I haven't done it for a while, but a very light and quick brush afterwards with a wire brush was all it needs, if that. Definitely worth trying, especially for bits that are hard to clean or get a wire brush into. It does work on "line-of-sight" with the steel connected to the other end of the power supply. Can't remember which is the anode or cathode :D

For rust removal, I use this https://bilthamber.com/product/deox-c/ absolutely brilliant. Just mix with water, check the bits in and leave it for a while. It removes all traces of rust and leaves a rust resistant coating on parts until they can be coated with whatever you choose. No toxic and it just works. :)

So - here's a bit I've just removed from the Merc I'm working on:

I've just put it into a citric acid bath. I'll do the "after" photo later!
