Quick answer
Clean your double walled glass teacup by hand with warm water and mild soap, using a soft cloth or bottle brush. Never use abrasive scrubbers or put it in the dishwasher.
Why hand washing matters
Double walled glass teacups are made of two layers of glass with a sealed air gap that keeps your tea hot and the outside cool. The dishwasher's high heat and strong detergents can break that seal over time, causing fogging or cracking. Hand washing keeps the insulation intact and the glass clear.
What to avoid
Steel wool, scouring pads, and abrasive cleaners will scratch the glass and ruin its transparency. Let the cup cool completely before cleaning—thermal shock from hot glass meeting cold water can shatter it. Also avoid stacking heavy items on top of the cup during storage.
Step-by-step cleaning and care
- Cool and rinse: Let the cup cool to room temperature after use. Rinse with warm water to remove loose tea residue. Do not use cold water on a hot cup. Always wait until the cup is cool to the touch before rinsing.
- Wash with mild soap: Add a drop of mild dish soap to warm water. Use a soft sponge or a bottle brush to gently clean the inside and outside. Pay attention to the rim and bottom edge where oils build up. A bottle brush reaches the bottom without scratching the glass.
- Rinse and air dry: Rinse thoroughly with warm water until no soap remains. Place the cup upside down on a soft, lint-free towel to air dry. Do not dry with a cloth that may leave fibers. Avoid towel drying to prevent streaks or lint; air drying keeps the glass clear.
- Remove stubborn stains safely: For tea stains inside the cup, fill with warm water and a teaspoon of baking soda. Let it soak for 30 minutes, then scrub gently with a soft brush. Rinse well. Baking soda lifts stains without scratching the glass surface.
- Store carefully: Store the cup in a cabinet away from heavy objects. If stacking, place a soft cloth between cups. Keep the lid (if any) off to allow airflow and prevent odors. Proper storage prevents chips and keeps the cup ready for daily use.
