The process disclosed is characterized by a first, cleaning, phase in which the corks are treated, particularly with stirring, at ambient temperature in an aqueous alkaline solution containing a mixture of sodium hydroxide, sodium silicate and hydrogen peroxide, by a second, drying, phase in which the corks are dried at a temperature of the order of 40 - 80 DEG C and by a third, disinfection, phase in which the corks are treated with an aqueous acidic solution containing a mixture of acetic and peracetic acid plus hydrogen peroxide in equilibrium, this third phase being followed by a further drying phase.
