Topic: Evaporust and Wiring

[midlife]

Yesterday, I played around with Evaporust and wiring, specifically a 1966 fuse box that was reasonably rusty.  After 1.5 hours, there was little improvement, so I went a full 17 hours (overnight!).  There was some improvement, but to tell you the truth, I was very disappointed in the results.  I think the issue is that the fuse box clips are cad-plated, nickel-plated, and copper cores, although some appear to be steel-cored.  Evaporust appears to work best on steel and iron rust.  The Evaporust did not affect the insulation of the wires or the bakelite fuse box itself. 

I think I'm going to stick with bead-blasting the fuse box and clips to get rid of the rust, followed by a coating of dielectric grease to prevent rust.

Here are the before, during, and after pictures:

You may want to wait longer Randy. I've had some parts that really didn't start to clean up until 3-4 days. You can scrub with a nylon toothbrush once a day and that seems to help

Well, that'll really drag out the timeframe for me to refurbish harnesses!  I can bead-blast the fuse box and any male/female bullet connectors and apply dielectric grease in less than 5 minutes. 

The important thing, though...is if anyone wants to apply evaporust, it doesn't hurt the wire insulation.

How old is your evaporust?  If it's been used a lot, it might not be as potent as it was.  Might try a new bottle.

Second use; the first was a test sample on a single bolt, nut and washer in a small jar.

Midlife, what temperature would your evaporust be during use ? It works faster when it's warmer.
I have a couple of fish tank heaters in the tubs with the evaporust, heats to about 80 degrees F.

This was in my climate-controlled garage: 76*.

I have had some but very few poor results with evaporust. You mentioned that zinc coated parts didn't work well. I've found the opposite with zinc. Took the rear 1/4 window slider plates and front side window frames which are both zinc coated steel and after a day of soaking any rust disappeared and zinc looked feashly plated. I have SS trim rings and GT caps soaking as I am posting.
