cleaning

[pistolpete]

SO I have a lot of parts to clean remove rust and degrease, what does everyone use . I have seen these tanks (parts washers) that you fill will fluid and spray, They look pretty good and our not expensive, but controlling fumes with a tank for of solvent?


Cheers

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.

try citric acid. buy granules and mix up

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...

Thank you great advise the electrolysis is currently part of my Sons science project, so I know what he's doing after school for the next few months Practical!!!

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 !

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!!

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

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!
