Hi Annie
If you look up this article or many others like it on the net the simplest and most effective disinfectants are 70% alcohol or one of the aldehydes for most organisms remembering that you are only disinfecting a hard surface with no visible volume of liquid containing organisms.  We are fortunate to have 2 Thermo cryostats which have an inbuilt decontamination system using concentrated formaldehyde which can be run overnight performing a defrost and decon and as the microtome is not in the refrigerated chamber there is no problem with ice build up in the moving parts of the microtome.
