When the operations are over, protect the parts more exposed to oxidation doing as follows.
• Use lukewarm water with a bit of soap to clean the parts;
• Rinse the parts thoroughly, without using pressurised and/or direct water jets;
• Dry the surfaces carefully using non-abrasive material;
• Pass over all the stainless steel surfaces using a non-abrasive cloth slightly moistened with
Vaseline to create a protective coating.
For appliances with doors and rubber gaskets, leave the door slightly ajar to let it air out and spread protective
talcum powder on the rubber gasket surfaces.
Air out the appliances and rooms regularly.
