I have some tools, screw drivers, hacksaw, tube cutters, sawzall,
grinder...that occasionally will come in contact with moisture, especially
when working with cutting plumbing lines or working outside when it
rained...I try to wipe the tools dry with a rag but sometimes it's hard for
example when I am cutting a sprinkler line and the sawzall blade extended
all the way into the dirt as I made the cut for the line as well as nearby
roots.

Even if I wipe it dry, moisture would have gotten inside the ball bearing
and I can't clean that anyways. Sometimes I spray some WD40 and tuen the
tool on for a second or two.

Recently a friend told me he has a neighbor that has a 5 gallon bucket of
sand, he then pour in a gallon of used motor oil so the sand is now soaked
in oil. Then when he finishes working with hand tools that may be wet he
insert these hand tools into the oil soaked sand bucket and leave them there
and that supposedly keep things from rusting? Anyone does this? I would
think this would not work for power tools you don't want sand to get
anywhere near the ball bearings.

What are your tips and tricks in keeping your tools in good condition
without too much hassle in cleaning them all the time?
