Learn how to clean, store, and maintain your Hasami porcelain tumbler to preserve its natural texture and stackable design. Simple steps for daily use.
Quick Answer
Hand wash your Hasami porcelain tumbler with mild soap and a soft sponge, avoid thermal shock, and store it nested with other Hasami pieces to protect the natural matte finish.
Why Hasami Porcelain Needs Special Care
Hasami porcelain is a blend of porcelain and clay, giving it a natural, slightly textured surface that differs from glossy ceramic. This unique finish is part of what makes each piece feel organic, but it also means that harsh scrubbing or dishwasher detergents can dull the texture over time. The modular design—where every Hasami piece shares the same diameter—makes stacking easy, but it also means you should avoid dragging items across the surface, as this can leave fine scratches.
The Hasami Porcelain Black Tumbler Small (USD 24.15) is a versatile piece that works for hot tea, cold water, or even as a small vase. Knowing how to clean it properly will keep it looking as natural as the day you bought it.
How to Care for Your Hasami Tumbler
- Hand Wash Only with Mild Soap: Use a soft sponge or cloth with warm water and a drop of mild dish soap. Avoid scouring pads or bleach-based cleaners. Rinse thoroughly so no soap residue remains on the porous surface. Dishwasher cycles can be too harsh and may dull the matte finish over time.
- Avoid Sudden Temperature Changes: Let the tumbler come to room temperature before pouring in hot tea or ice water. Placing a cold tumbler directly under boiling water can cause thermal shock and hairline cracks. Always pre-warm the tumbler with a splash of hot water before adding boiling liquid.
- Dry Immediately After Washing: Wipe the tumbler dry with a soft, lint-free cloth instead of air drying. Water spots can leave mineral deposits on the matte surface, and standing water in the bottom may promote mold if stored stacked. Stacking damp tumblers can trap moisture, so make sure each piece is completely dry before nesting.
- Store Nested or Separately: Because Hasami pieces share the same diameter, you can stack them neatly. Place a soft cloth or paper towel between stacked tumblers to prevent the base of one from scratching the interior of another. If storing individually, keep them upright and away from heavy items that might chip the rim. The modular stacking design is space-efficient, but the matte finish can mark easily, so always use a liner.
- Remove Stains Gently: For tea or coffee stains, make a paste of baking soda and water and rub it gently with your fingers or a soft cloth. Rinse immediately. Do not use bleach or abrasive powders, as they can permanently damage the texture. If a stain persists, soak the tumbler in warm water with a denture tablet for 15 minutes, then rinse.
