Clean Kitchen Practices

  • Never pour oil and/or grease down any drain or into any toilet

  • Use less oil and liquid oil instead of solid grease or lard

  • Scrape food scraps into designated trash receptacle

  • Dry wipe, with a paper towel, all oily/greasy dishes, pots, pans, containers and utensils prior to putting them into hot water or placing them into the dishwasher

  • Collect, recycle or dispose of used oil/grease through an approved grease hauler – Liquid Waste Transporter (LWT)

  • Use baskets and/or screens in all kitchen sinks to help prevent food debris from entering the drains

  • Make sure all floor drains are properly screened

  • Capture the oil and grease accumulated in ventilation and exhaust hoods through routine cleaning and filter changes

  • Clean (pump) grease interceptors on a regular basis

  • Keep grease interceptors well maintained and properly working

  • Make sure the used oil/grease intended for the oil/grease dumpster ends up inside the dumpster instead of spilled on the surrounding area
