Our holiday gatherings may be smaller this year, but greasy leftovers can still cause huge problems. When it comes time to clean-up, whatever you do — don’t dump the scraps down the drain! Fats, oils, and grease can clog pipes, causing nasty sewage backups and serious damage to your home. So instead of rinsing in the sink, scrape, pour and wipe your greasy scraps and toss them in the trash.
