Quoted from PinJim:
I’m kinda blown away by the molasses thing. Who knew? Something to try next time. How do you keep parts from flash rusting after removal?
You have to work them. I have a 4" tube for legs as the other poster does. I read 2 oz. per gallon does the trick but I make my mix stronger ( you know, the weed killer says it will do 5000 sq. ft. when truth is closer to 1000 sq. ft. )
The stuff does get rank. It is an organic product and sweet. The flies and moths got trapped in my solution all of the time. It will get moldy. THe water evaporates but like the other guy, I just keep adding water.
For legs with light rust a couple of days soak works. For the real heavy rust down at the bottom I may soak for 10-14 days. If the chrome is gone all you will have left is black spots; Same with any rust removal process.
As soon I pull them and rinse them I manually dry them with a towel. I don't don't let them air dry or surface rust will appear. On the inside of all my legs I will spray them with silver or gray paint. Some times on the outside I will hit them will some spray can clear or just some wax.
I did a Gottlieb coin door with vinegar once like the one you are doing. Following the grain I scrubbed with a scotch brite and toweled it dry. Then hit it with some wax. But you might try some spray can clear to help keep the rust away. Semi-gloss clear might look close to natural.
Jay Leno's Garage had a father/daughter business team on one time who sells a special product to keep the rust from coming back for around a year. I can't remember the product but it looked cool.
P.S: I discovered the molasses trick when I was watching a you tube video of a couple of guys removing rust from some old car body panels. He was real cagey about what they were using and talking like they had something proprietary but said it had a sweet taste. In the end, the only these guys had were some big soak tanks.
I googled how to remove rust and the molasses thing came up big time. All of these car guys are de-rusting their old car skin panels with molasses and they were proud of what they were doing.
