Learn the best way to clean double-wall glass tea cups, prevent tea stains, and keep your Stellar double-wall cup looking clear and shiny for years.

Quick Answer

Clean your double-wall tea cup by hand with warm water and mild dish soap, using a soft sponge to avoid scratching the glass. Dry it immediately with a lint-free cloth to keep it clear and streak-free.

Why Double-Wall Cups Need Special Care

Double-wall glass tea cups like the Stellar design are loved for their sleek look and heat retention, but the air gap between the two layers can trap moisture and stains if not dried properly. Unlike regular mugs, you can't just toss them in the dishwasher without risking damage to the glass or leaving water spots inside the gap.

Hand washing is the safest method because it lets you control the water temperature and avoid harsh detergents that can dull the glass. Also, sudden temperature changes can cause thermal shock, so always let the cup cool before washing.

Trade-Off: Dishwasher vs. Hand Washing

While some double-wall cups are dishwasher-safe, the high heat and strong detergents can gradually cloud the glass or weaken the seal between layers. For the Stellar cup, we recommend hand washing to preserve its clarity and longevity. If you do use a dishwasher, place it on a gentle cycle and remove it promptly to air dry, but expect a shorter lifespan.

Step-by-Step Cleaning and Care Routine

Let the cup cool completely: After finishing your tea, wait until the cup reaches room temperature. Plunging a hot glass cup into cold water can cause it to crack due to thermal shock. Never wash a hot double-wall cup with cold water.
Rinse with warm water: Hold the cup under warm running water to remove loose tea leaves and residue. Avoid boiling water, as extreme heat can stress the glass. Use warm, not hot, water for rinsing.
Wash with mild dish soap and a soft sponge: Apply a drop of mild dish soap to a soft sponge or cloth and gently clean the inside and outside. Avoid abrasive scrubbers or steel wool, which can scratch the glass surface. Stick to non-abrasive tools to keep the glass clear.
Rinse thoroughly: Rinse the cup under warm water until all soap suds are gone. Leftover soap can leave a film and affect the taste of your next cup of tea. Ensure no soap residue remains inside.
Dry immediately with a lint-free cloth: Use a soft, lint-free towel to dry the cup right away. This prevents water spots and keeps the double-wall gap from trapping moisture, which can cause cloudiness over time. Drying immediately is key to maintaining clarity.
Store upright in a safe place: Place the cup upright on a shelf or in a cabinet, away from the edge to avoid accidental knocks. Stacking cups can scratch them, so store them separately or with a soft cloth between. Proper storage prevents chips and scratches.
