Alcohol has been shown to bind blood and protein
to
stainless steel. The use of alcohol with
dental
instruments should therefore be avoided.
6.58 It is not good practice to refill spray bottles used to
apply cleaning or disinfecting solutions. Bacteria
can contaminate the bottles and become adapted to
these solutions and grow in the spray mechanisms
Such bottles, whether supplied pre-filled or empty, should be single use.
So, no alcohol on instruments but spray (any) is allowed as long as bottles aren't refilled.
(there is a discussion that
alcohol free wipes/spray damage the surface of more or less everything so...watch this space)
