Evapo-Rust vs Apple Cider Vinegar

[Skamaniac]

A few days ago I decided to do an experiment to see what worked better for rust removal - Evapo-Rust or apple cider vinegar. A month ago or so I recovered an old gate hinge that was equally rusted on both ends. I filled one soup can with the Evapo-Rust and the other with the apple cider vinegar. Then I placed one end of the hinge in each can and left it for 3 days. I pulled it out, gave each side 5 strokes with a metal brush and rinsed.

I was surprised that the AC vinegar appears to have worked better. In the photo, the Evapo-rust side is on the left, vinegar on the right.

That apple cider vinegar works really good, I've used it on certain things. I prefer electrolysis though the the vinegar acid can eventually eat right into the metal. I usually do electrolysis cause I can keep a close eye on the progress.

Very scientific, thanks for sharing the results!
Always good information to know.
Too bad I cannot stand the smell of vinegar.

Last year my brother was razzing me about all the different methods that I had for cleaning my finds, soon after I held a glob of rust in front of him, he said whats that crap, I said it's a knife and I am going to show you what apple cider vinegar can do. :grin:

I have an electrolysis setup also, but I have to get a new power source for it. I'm looking for an old-school battery charger without all the electronic safety features.

Here's the last thing that I did electrolysis on. I used a 10amp battery charger on this with baking soda and water for electrolyte.

Good post . Personally I use apple cider vinegar . It works , it is cheap, and it is simple; and doesn't involve a fancy set up, electricity or a battery. Down side is it smells so my set up is an outside garage. I let the item soak for a few days then wire brush it , let it soak more if need be wire brush it again and then dry the object and spray it with clear lacquer. I'll put the results up against electrolysis any day.

The new charger I have senses something isn't right and automatically shuts off, like a GFI on on an outlet does. The old chargers just let the power go through no matter what. With the newer charger I have to connect it to a battery in need of charging and then attach the electrolysis to the the battery.

Hi My Fellow TH'er
Congrats on the find and it appears to have cleaned up reasonably well. That looks like a Military issue knife that was used in Vietnam. As I recall they were referred to as a 'TL-29'. I sure wished that I had kept the ones that my late Dad brought back from Vietnam as he had a local change out the plastic handle pieces with nice Mahogany wood. I get up to Jackson, Michigan once a year to visit relatives and do a little TH'ing in the local parks. The soil is so much easier to dig there compared to the clay/rock of Northern Virginia. It is nice here in Wilmington, NC lots of sand. Congrats again!
