I am using a regular cloth, it is extremely cheap, you can use same or some old cloths. Wiping that surface layer was easy, but still was a harder dirty layer. I guess that was a layer as a result after being so long in white vinegar bath or just a tarnish after so many years.

Now, when I removed the surface rust successfully, it is time to remove this tarnished layer. For that I will use plain steel brush, I am quite sure you have some in work shop or you can buy one. Steel brush is dirty cheap!

Wow! I am pleasantly surprised. This is going so easy and so quickly. Several times with steel brush and rust is gone. Nice! Check out how nicely vinegar (and steel brush) has removed all rust on this part of multi tool! Looks like brand new.
