How to Clean a Reusable Coffee Cup

Why Reusable Coffee Cups Need Daily Cleaning

Reusable coffee cups accumulate coffee oils, milk residue, and tannin stains quickly. The lid and drinking spout are particularly prone to mold and bacteria if not cleaned thoroughly after every use. A proper daily clean keeps your cup tasting fresh and hygienic.

What You'll Need

• Dawn Platinum Dish Soap
• Dish brush set
• Cup lid gap cleaning brush set
• Bottle Bright cleaning tablets
• Baking soda
• White vinegar

Daily Cleaning After Every Use

1. Disassemble completely — Remove the lid, any silicone sleeve, and the gasket. Each part needs separate cleaning.
2. Rinse immediately — Rinse all parts with warm water right after use to prevent coffee and milk residue from drying.
3. Wash the cup body — Add a drop of dish soap and scrub with a dish brush.
4. Clean the lid thoroughly — Use a lid gap cleaning brush to scrub the drinking spout, hinge, and all crevices. This is where mold most commonly grows.
5. Scrub the gasket — Remove and scrub the silicone gasket separately.
6. Rinse all parts thoroughly and air dry with the lid off.

Removing Coffee Stains

For stained cups, sprinkle baking soda inside the wet cup and scrub with a brush. For stubborn staining, drop a Bottle Bright tablet in warm water and soak for 15–20 minutes — it removes coffee stains and odors without scrubbing.

Removing Milk and Dairy Odors

Milk residue causes the worst odors in reusable cups. Rinse immediately after use — never let milk sit. For existing odors, soak in equal parts white vinegar and water for 30 minutes, then wash with dish soap and rinse thoroughly.

Is Your Reusable Cup Dishwasher Safe?

Check the manufacturer's label. Many reusable coffee cups are dishwasher safe on the top rack, but lids and gaskets should be hand washed to preserve the seal. High heat degrades silicone gaskets over time.

Final Thoughts

The key to a clean reusable coffee cup is rinsing immediately after use and cleaning the lid thoroughly every day. A lid gap brush is essential for the drinking spout and crevices. Weekly Bottle Bright soaks handle stains and odors effortlessly.
