It’s okay to pour grease down the drain as long as I run hot water.

Hot water only gives the illusion of dissolving grease. The grease will eventually cool and build up in the pipes.

Liquid oil at room temperature won’t clog the pipes.

Liquid cooking oils, like canola oil and olive oil, float on wastewater and easily adhere to sewer pipes.

Using dish soap will prevent grease from hardening in my pipes.

While dish soap temporarily breaks up grease as you wash your dishes, the soap will eventually lose its effectiveness causing the grease to solidify in the pipes.
