Begin with warm water and mild detergent
Rinse soon after use, then wash with a soft sponge and a small amount of detergent. Too much detergent can be harder to rinse away and may leave a film.
For mineral spots
Soak the mug briefly with a diluted food-safe descaling solution such as white vinegar and water, then rinse thoroughly. Do not combine cleaning chemicals, and follow the mug maker's care instructions.
Dry before spots return
Use a clean, lint-free cloth or allow the mug to drain fully. If your water is mineral-heavy, hand-drying can reduce visible spotting.
Avoid abrasive tools
Steel wool and gritty cleaners can scratch the surface. Replace the mug if you find a crack, a sharp chip or damage that could worsen with heat.
