[Coral-List] Underwater Drill Oil Toxicity

I ordinarily just lurk on this list.  I hope I am not out of my place
in suggesting to look for "refined vegetable oil."  I have seen
reference somewhere, don't remember where.  I am hoping to use it for
my knife sharpening stones, since vegetable cooking oil seems to go
rancid.  Don't know whether this is relevant.

We have used the same drill for three years now, keeping it alive by total submersion in pneumatic tool oil between uses.  After a recent discussion with a colleague from the University of Hong Kong, it was brought to my attention that pneumatic tool oil and many other oil and hydrocarbon lubricants can be quite toxic to the reef environment and that common household vegetable oil works just as efficiently at keeping the drill lubricated with minimal toxicity levels.  I have tried in the past to wash my tools thoroughly before use but it's quite hard to remove all traces of the toxic oil.  Just a suggestion in hopes that we can tailor our methods and practices to reduce our impact on the environment we enjoy working in as much as possible.
