Abstract
A servicing composition which is sprayed from a container on or into a medical instrument e.g. a dental handpiece. The servicing composition includes an oil and propellant mixture for lubrication purposes but, for improved sterlizing purposes during subsequent hot-air heating and sterilizing of a medical instrument, an alcohol-aldehyde active substance combination in a proportion of 5 to 15% by weight is added to the mixture which is sprayed on the instrument. The preferred alcohol is isopropanol and the preferred aldehyde is formaldehyde or a succinic acid dialdehyde complex, and the preferred ratio of alcohol to aldehyde is 1:1.
