OutdoorKing Repair Forum Forums Restoring, Customising and Modifying Paint and Decals Rust and Corrosion - Removal Options ?

Has anyone used...

Metal Rescue - pre-mixed about $50/5L @ REPCO, apparently re-usable

Evapo-rust - pre-mixed about $88/5L @ Supercheap (much more expensive than Metal Rescue).. or for Concentrate $100 (makes 6L) from the website. Also apparently re-usable

Rust Bucket by 'Action Corrosive', comes in 1L concentrate(makes 5L) - about $40. Unknown if re-usable.

Have read a few reviews of Metal Rescue and evapo-rust.. not much about Rust Bucket though.

Just wondering how they may compare to, say, using Acidic Rust Removers and Electrolysis ?
From the pics/videos, they seem to clean up nice.. and being water based, seems easier to clean? plus I 'think' I read they don't flash-rust as easily as other methods??



Thoughts?

G'day Widget,

Well, all I can say [as a field chemist with Baker Hughes in a past life, which included quite a lot of oilfield corrosion related work and training] is that there's far too much 'snake oil' in the blurbs for all of those products, for my liking.

And none of them have a readily downloadable MSDS available.

So for me, the bottom line is that they may well 'work like it says on the packet'. But their pricing is highly likely to be in the 'predatory' class, for what's actually in them...

What's everyone's thoughts about vinigar or coke? Not interested in connecting power supplies up etc I just want an easy old school method

G'day Tjames,

Well, it doesn't get any more old school than the Molasses/water bath described earlier in this thread, and also pictured in this one; https://www.outdoorking-forum.com.au/forum/u...-160cc-isolation-project.html#Post105218

Coke is just an exy way of buying the 'active ingredient', which is actually the Orthophosphoric Acid in it! The Food Additive No. is 338 for that stuff.

Thanks alot for that. I want to give it a go!
Got a camando that I want to restore

Yes I find the molasses bath a great thing, yesterday threw in the cutting disc off a Victa Cortina 2 at about lunchtime today pulled it out a gave it a pressure wash which really blasts the crud off and it is now back in overnight.
I would say lunchtime tomorrow another blast and it will be ready for a bit of a sand and I spray with Lanotec to stop the rust flash until I am ready to paint, when ready I wash off in the parts cleaner pressure wash wipe over with wax and grease remover before painting.

Beech

Yes Beech, I have had a similar result with it - just strips it right off. An older guy I know bought a few 44gal drums when a business closed in the 80s and soaked a tonne of parts in it before it became so saturated it lost effectiveness.

For any WA guys, Mirco Brothers of Neerabup and Bibra Lake have molassis by the kg for $1.6/kg. About the cheapest I have found over here so far.

BYO bottles or they also have a 15l pail with lid for $4.

Plus, if you want epsom salt for the lawn for spring, its $25 for 25kg. Tried to calculate the cost it would be at bunnings but typing 6.85/kg x 25 into the calculator made my eyes water too much haha
