Learn how to clean your 24Bottles Casa Mug 340 ml to remove coffee stains and odors, plus daily habits to keep it looking fresh.
Quick Answer
Clean your Casa Mug 340 ml by hand with warm water and mild dish soap after each use, and give it a deeper baking soda treatment weekly to lift coffee stains and odors.
Why Hand Washing Matters
The Casa Mug's double-wall insulation keeps drinks warm longer, but that same design makes it sensitive to extreme temperature changes. Dishwasher cycles can be too aggressive and may affect the vacuum seal over time, so hand washing is the safer choice for long-term performance.
The 340 ml size is perfect for a home coffee ritual, but it also means residues can build up quickly if you don't rinse promptly. A quick rinse right after finishing your drink makes later cleaning much easier.
Step-by-Step Cleaning Routine
- Rinse Immediately After Use: Empty the mug and rinse with warm water right after finishing your drink. This removes most coffee residue before it dries and stains. Never let coffee sit in the mug for hours; dried residue is harder to remove.
- Hand Wash with Mild Soap: Use a soft sponge and a drop of mild dish soap with warm water. Gently clean the inside and outside, then rinse thoroughly. Avoid abrasive scrubbers; they can scratch the surface and dull the finish.
- Deep Clean with Baking Soda: For stubborn stains or odors, add a teaspoon of baking soda to warm water in the mug, let it sit for 15 minutes, then scrub gently and rinse. If stains persist, repeat the soak, but do not use bleach or harsh chemicals.
- Dry Upside Down: After rinsing, shake off excess water and place the mug upside down on a drying rack. Ensure it is completely dry before storing. Trapped moisture can cause odors or mildew, so air-dry fully.
