I followed this from the start, but refrained from comment- but took all on board and immediately applied it to practice.....I've had a pipe cutter that sat for a while unused in dampish conditions, and when i needed it the cutter wheel was totally seized -lucky the other two rollers were ok after some work.....that was at least a few years ago...was on a job at the time and a guy had a product I can't remember the name of but swore it was the ducks nuts only thing I could find that it may have been was 'Yield' - no go, now I'm swearing back at him 40 bucks a can f*** off, so Tried Olevs idea and the other day pulled it out of the soak.......voila !!!!!. I'll be using that again...still needed a bit of work but not much
