Thread: A ? or 2 on Evapo-Rust.

Seems like an ideal rust removal option. For those of you that use it: what sort of container do you use when soaking razors in the stuff? From what I read on the packaging, it's "safe on most materials". But would it eventually eat through something like a disposable Tupperware? Also: is there any kind of gas production? I'm not really worried about fumes, but if I need to put a lid on it to safeguard against spills during the soak, it would be pointless if gasses just popped it off anyway lol.

Looking forward to your thoughtful responses!

Sincerely,
Crawler.

Nope, empty water bottle works great for a couple of blades. Screw on the top and check it in an hour. If it needs more another hour, 2-3 should get most anything off.

Do not throw the solution away, just screw on the top and mark what is in the bottle, it last a long time, years even when it is brown dirty, still working.

Rinse in water and dry.

There is an old post I made a couple years ago with photos on Evaporust.

Just use an old Chinese/ takeaway tub here works fine for me
I have left a blade overnight with no problems

A big test tube holds a couple of blades.

Word of caution: Do not let the level of the solution get below the top of the blade. The blade must be fully immersed.

Even a couple of days is OK

just tried this rust dissolver gel a few days ago with good results. I like that it's a gel and I can apply it only to the rusty bits. Nice for scale on restorations and lightly etched blades. It took off all the stubborn black rust in about 10 minutes.

I grab a tall kitchen glass... tie the blade to a string, and the string to a pencil... hang the blade from the pencil resting across the top of the glass.

Once done, the glass goes in the dishwasher... good as new.

I had a very poor experience with Evapo Rust. I left it on a blade over night and it came out blackened:



It's almost as if it had been blued and it did nothing for the black rust in the pits on the blade.

From the Evapo Rust web site:
"Q) I get a black film on some parts after using EVAPO-RUSTTM. What is it and how do I remove it?
A) The black is carbon from the steel. Generally high carbon steel is used in making items that are flexible (e.g. springs, saw blades) High carbon steel and tool alloy steel items when de-rusted will have a darker appearance. Much of the carbon can be removed simply by wiping with a cloth."

The carbon on the blade did not wipe off, not much with polishing paste either. I had to use green rouge on my buffer to get the blade clean again.

Not to mention the possible effects of decarbonizing the steel a little.

I won't do that again.

I get the exact same blackening with the Evapo-Rust, and it literally just wipes off with 1000 grit sandpaper. After a first round with the 1k sandpaper, it's gets a scrub with toothbrush and toothpaste, then a good long round of sanding with the 1000 grit, then 2k, 3k, then 4k grits and I end up with a close to mirror finish.

Same experience with rubbing off for me, too... though I used a low grit sandpaper to try and get the rest of the blob off that EvapORust did not get off. (soaked one blade twice, 24 hours each, sanded, another 24 hours, sanded... this was a serious blob!)

I wonder what the difference was in the steel that caused Heart's stain from hell?
