Precautions
When scraping o heavy deposits of grease or oil from stainless steel equipment, never use ordinary
steel scrapers. Particles of ordinary steel may become embedded in, or lodge on, the surface of the
stainless steel. These will rust, causing unsightly stains and possible contamination of food. Where it
is necessary to scrape, use stainless steel, wood, plastic or rubber tools.
