Evapo-Rust

[Dronic69]

Evening All,

Just curious in those that may have used the "Evapo-Rust" product?

It states that it will remove rust and won't affect any paint work underneath?

I have an item (Mild Steel) that has surface rust both on the bare steel which also extends over a part painted section.

The before and after photos looks promising as highlighted in this BOCN thread:

Evaporust rust remover on my 1941 M42 3". Step by step.

I do not want to damage the yellow paint on this shell. The rust is thick in some places, hopefully not deeply pitted under the rust. Hazord recommends Evaporust, I found it at O'Reilleys auto store, $10. I jumped right in and followed directions. I painted the liquid on, wrapped in a rag, used...

Anyone else obtained similar results?
Is soaking the item the way to go?

All feedback and thoughts welcome.
Thanks
Cheers
Drew

I use it. If you leave it too long - over night, etc - it could give you some issues, but use it per the instructions and it is a miracle worker. You can re-use it a number of times depending on how much rust you actually remove, but it takes longer (thus the overnight issue). I buy it by the gallon.

Firstly, thank you for the great feedback!
Yeah I would be closely monitoring the progress.

Interesting ......according to the website, it states that it doesn't affect non-oxide paints:

From my limited painting knowledge, oxide paints are normally used for anti-rusting purposes - i.e. protect bare steel etc.
How would one know if a non-oxide /oxide paint was used? (apart from testing a small area)

The item I have in question is a torpedo striker mechanism with attached whiskers - of which the tips have been painted black (looks to be the original paint job)
Were most projectiles painted with non-oxide paints?
Thanks
Cheers

It's a good product, but one word of caution. Immerse the whole object otherwise you may well get a 'tide' line which will not disappear with subsequent treatment. It depends how long you leave it but I learnt this to my cost.

Concur with all previous comments. Good stuff.
I've left items to soak for a week with no ill effects. Only paint with rust incursions is affected. Otherwise, paint is untouched.
My 5 gallons has been in a bucket in excess of 5 years. Have regenerated with water.(Keep a lid on it, it evaporates.) The active ingredients are still producing rust removal results.

I left a projectile with original paint (presumably enamel) in Evapo Rust for 4 hours and there was no paint left. So don’t use it for too long and monitor frequently

It is the good stuff.

A couple of reference pics of the item in question - IMHO it's the original paint (hence I don't want to "rush" into it) as I have seen another one with the exact same black painted areas:





I'll definitely give it a ago and closely monitor the process.

Thank you all for all the great feedback!!!

Have used it. Find it does also remove some paint.

The other option is perhaps used a rust converter, which attacks the active rust - but is more acidic.

I'm not worried re the bare metal as I can get the Dremel onto those parts...........

Hum - I'll sleep on it

It is a great product. The photo shows a before and after photo of my Linco needle firing pistol.
This is how it looks after a couple of hours submerged in Evapo Rust,
and no cleaning or mechanical cleaning has taken place.
This is how it literately looked after I pulled it from the Evapo bath.

Workshop Hero Metal Rescue Rust Removal Bath 5L - MR5​

SKU: A1290583

Haven't tried this product, but looks to be similar. The example in their video seems to retain the paint. available from Repco.
I note that Evaporust is now a CRC product, previously was an independent brand, must have been bought out or sold the name?.

Thanks for this - I checked it out and it seems to be almost an identical product - instructions /cautions were virtually the same.

Yes - CRC now distributes the product.

Well, there must be a God (which one I'm not sure off ) as I found a perfect Evapo-Rust test piece - a small hand axe with similar surface rust and BLACK paint:





Interesting, the instructions recommend rinsing the item in water prior to dropping it into the solution:

To my shock /horror - while I was rag drying it (this was after just rinsing in cold water) the black paint started to come off on one side -



The other side seem less affected or not affected at all


OK as it was just a test piece into the bucket it went - monitoring the progress.

After approx. 1 hour:





I rinsed again and carefully dab dry - after which the paint section seems to have now stabilized.

I tested the striker and as expected the black painted sections didn't show any signs of coming off after the water rinse Phew!
(Yeah - they don't make them like in the old days!!)

Interesting results.......

The striker mechanism was soaked for up to six hours with regular monitoring every 30-60mins.
Most of the bare metal rust was removed, however there were still rust spots present on the painted areas even after 6 hours albeit diminishing some what.
I removed the item, rinsed then let dry - after a short time very light rust was forming all over.
I decided to used a rust converter and that actually removed the remaining spots on the painted areas.
Let dry and dremel the bare metal areas with a small circular wire brush attachment.

Here is the final result:





Just for comparison:




Note:
I was conscious of not wiping/ rubbing the painted areas while the item was in solution and even after rinsing, left the item to drip dry. Seems the solution does to a degree softens the paint!
Once dry the painted areas could be handled as normally.

Quite happy with the result!
Cheers

BTW - It is the original paint!!!!

Evaporust claim too that if you leave a clean solution on the item it will resist corrosion. Handy if you have a delay before painting. Bare steel will rust in front of your eyes otherwise!

Perhaps I should just do away with the suggested water rinse after soaking and let it drip dry!
CRC also recommends using RUST-BLOCK - yes another one of their products
