Grease occurs when fats from food melt under heat such as frying, boiling and baking, etc. Grease is deceptive because it is a liquid after cooking, but eventually cools into a solid. Pouring it down the drain means that at some point, it will cool on the pipes in the collection system, harden, and then start a clog.

Unclogging Strategy: Pour liquid grease into a grease can or other container with a lid and place in trash can once it has cooled. Running hot water over greasy cookware in the sink only pushes it into the pipes where it hardens. Read the FAQs for more ideas.
