Abstract
A method of cleaning a pressing and/or curing apparatus includes providing a cleaning mat on the interior of the apparatus and subjecting the cleaning mat to elevated temperature and/or pressure. The cleaning mat is pre-treated with a cleaning composition which preferably includes sodium carbonate. The method obviates and/or reduces the need to disassemble a pressing apparatus (e.g., remove die sets) for periodic cleaning.
