Keeping your yeti tumbler clean isn't just about appearance -- it's about hygiene and performance. Here's how to do it right, with the supplies you probably already have at home.
Remove the lid, gasket, and any other removable parts. Set aside for separate cleaning.
Fill the tumbler with warm soapy water and scrub with a bottle brush. Reach all the way to the bottom and around the inside.
Wash all lid parts thoroughly. Use a small brush or toothpick to clean inside the gasket groove where mold can grow.
For lingering smells, fill the tumbler with warm water, add 2 tablespoons baking soda and 1 cup vinegar. Let fizz for 30 minutes.
Rinse thoroughly and air dry upside down on a drying rack with all parts disassembled.
