Polypropylene Plastic
Polypropylene is thermoplastic and stands
temperatures under boiling temperature of water. It is
molded into tubs and parts for washers and dishwashers
and other items; and made into fibers for carpets and
upholstery, when the name "Olefin" is often used, as a
trade name. It is not affected by most common alkalis
and acids, but is damaged by solvents, boiling water, and
citrus fruit rinds.
Avoid contact with boiling water, high heat, flame
such as cigarettes, and abrasives.
Wash in warm sudsy water. Never use scouring powder.
