This (or similar) was around here, in Australia, in the 1950s when I was 
an apprentice in a powerhouse.

The old tradesmen preferred to hand-scrape the white-metal (babbit) 
bearings, which they could do much more quickly. However I experimented 
with it later when I had a power house of my own, but it was slow, 
especially as I took special precautions to wash all remnants away 
afterwards.

I believe the abrasive material was pumice.
