Machine cleaning
Cleaning must be carried out after every day of use.
Use hot water, a neutral detergent/detersive if neces-
sary, and a soft brush or sponge. If another type of
detergent is used carefully follow the manufacturer’s
instructions and observe the safety rules given in the
information cards provided with the product or sub-
stance.
In order to reduce the environmental impact of pollut-
ant substances, clean the equipment (externally and
internally where necessary) with products that are
more than 90% biodegradable.
