Never pour grease or cooking oil down drains. They solidify in pipes and choke drains.
Don’t put potato peels, poultry skins, bones, rice or pasta down the garbage disposal. Disposals can handle scraps in very small quantities but most food waste belongs in the trash can.
Make sure the disposal is running before you drop in small food scraps.
Don’t flush wet wipes down toilets. Most won’t dissolve and can clog pipes.
