So, I tried the advice I got on the old “Vostok Mods.” thread on how to improve the scratched (stainless steel) case on my vintage Amphibia, and thought I’d report back.
In essence, the instruction looked like this (or read here):
First use steel wool and polish the case all over (in the direction of the grains).
Then move onto Scotchbrite (also in the direction if the grains).
Finally you have 2 choices to finish it off, either a Cape Cod cloth (Amazon), or Autosol (Amazon).
You will notice a massive improvement from the steel wool alone, and may even want to stop at that stage.
I made myself some simple tools attaching the steel wool and Scotchbrite to the end of the handle of tea spoons using cable tie.
To be honest, I couldn’t see any difference from the steel wool and Scotchbrite treatment at all. I kept going with pretty high pressure and speed on a small area for about 15 minutes with the steel wool first and then for about 15 minutes with the Scotchbrite. It was pretty laborious...
I should mention that before I did this I had cleaned the case using first detergent and a toothbrush, and then toothpaste and a toothbrush. It could be that the polishing effect of the toothpaste had already done what could be done using steel wool!?
The Autosol on the other hand made a nice difference making the stainless a lot shinier, but as far as I could see it didn’t remove (or add) any scratches.
So, I guess I won’t be using steel wool and Scotchbrite again.
