Hi Rose Marie: My dentist also saves her old drills (burrs for
polishing, etc.) for me - in fact lots of her little instruments as
they get worn down for her job, - and gives them to me. I simply drop
them in a pan (especially used for this) of water and boil the heck
out of them, along with a thorough washing of bleach and soap. I
rather imagine this helps. Sometimes when her office has time, they
chunk everything in the autoclave and give it to me sterilized. But
then I chunk it on my filthy workbench so…go figure.
I think early on boiling used to be the way even doctors treated
their instruments and was the basis on which the autoclaves were
designed. Be that as it may, yes, I do think one must be somewhat
careful with the things you get, but I’ve made it to the ripe old age
of 79, have used these drills from some years now, and haven’t had
any major problems with them and am not anticipating any problems
from here on out.
But then I grew up using asbestos hot pads, painting with lead based
paint, drinking water out of the hose, going barefoot and getting
cuts all the time and somehow plain old soap and water seemed to keep
me going. I just think today sometimes we get too carried away with
fear of “germs”. We need to be careful, but we also need to not worry
ourselves to death either.
