Why Your Color Changing Glass Cup Needs Special Care
A color changing glass cup adds a playful pop of color to your iced coffee, cold brew, or any cold drink. But that color-changing effect comes from a heat-reactive vinyl decal that won't survive a dishwasher cycle or a microwave zap. The good news: keeping your cup looking new is simple if you stick to a few basic habits.
What the Manufacturer Says About Care

Hand Wash Your Color Changing Glass Cup in 3 Steps
Hand washing is the only recommended method. Here's how to do it without damaging the design.
- Rinse immediately after use: Rinse the cup with cool or lukewarm water to remove residue. Avoid letting coffee or tea stains dry on the vinyl.
- Wash with a soft sponge and mild soap: Use a non-abrasive sponge and a gentle dish soap. Scrub the glass body and the vinyl decal gently. Do not use steel wool or scouring pads.
- Air dry or towel dry: Let the cup air dry on a dish rack, or dry it with a soft, lint-free towel. Avoid high heat from a drying cycle or direct sunlight.
What About the Lid and Straw?
The color changing glass cup does not come with a lid or straw unless you add them separately. If you purchase the optional bamboo lid and borosilicate straw, treat them with the same care: hand wash only, and avoid the dishwasher. The bamboo lid should be dried promptly to prevent moisture damage.
What to Avoid to Keep the Color Changing Effect
The color-changing vinyl is the star of the show. To keep it working:
- Never put the cup in the dishwasher or microwave.
- Avoid soaking the cup for long periods. Prolonged exposure to water can weaken the adhesive.
- Don't use harsh chemicals, bleach, or abrasive cleaners on the vinyl.
- Handle the cup carefully. It's glass, so dropping it can shatter it.
Storing Your Color Changing Glass Cup
Store the cup in a cabinet away from direct sunlight when not in use. Extended exposure to UV light can fade the color-changing properties over time. If you stack cups, place a soft cloth between them to avoid scratching the vinyl.
