How do you remove the coffee smell from an insulated cup?

- Baking Soda: Fill the cup with equal parts baking soda and hot water. Let it sit for several minutes, then scrub the inside of the cup with a sponge or brush. Rinse thoroughly and let it air dry.

- Vinegar and Water: Mix equal parts white vinegar and hot water. Fill the cup with this solution and let it sit for at least 30 minutes. Scrub the cup with a sponge or brush, then rinse it thoroughly.

- Dishwasher: If your insulated cup is dishwasher-safe, you can also place it in there along with a cup of white vinegar. Run a hot water cycle and let the cup air dry.

- Oxygen Bleach: Fill the cup with hot water and add enough oxygen bleach powder to create a paste. Let it sit for several minutes, then scrub the cup with a sponge or brush. Rinse thoroughly and let it air dry.

- Citrus Peels: Place the peels of citrus fruits like oranges, lemons, or grapefruit in the cup and add boiling water. Let it sit overnight, then rinse the cup thoroughly. The citrus will help remove odors and freshen up the cup.
