Still have old Kerbey queso tucked in the back of your fridge? Did you forget about that half-finished smoothie you promised yourself you would drink? Today’s the day to throw it away and start fresh.

According to National Day Calendar, a website dedicated to honoring every possibly holiday on the calendar, Nov. 15 is National Clean Out Your Refrigerator Day. The day originated in 1999 from Whirlpool Home Appliances’ home economists, the website said.

“It is said that they created the holiday to encourage people to clean out their refrigerator in advance of the upcoming holidays,” the site reads. “At that time, the company even had a toll-free hotline that people could call into for cleaning tips.”

Observing the holiday can be done as thoroughly or easily as you want. Take the time to care for your overworked refrigerator. Empty the entire thing, wipe down the sides and the shelves, and toss any moldy or expired food. If you’re feeling really fired up, try vacuuming under the fridge too and clean out all those crumbs you surreptitiously kicked under there.

Old food is often pushed to the back of your refrigerator shelves & gets forgotten as new food is put in front
