Quick Answer
Hand wash your Wuthering Waves Tidal Letters ceramic mug with mild soap and a soft sponge to preserve the printed design. Avoid the dishwasher and abrasive cleaners to prevent fading or scratching.
Why Hand Washing Matters for Anime Mugs
The Tidal Letters mug from FUN4YEAH features a full-color character print that is applied to the ceramic surface. While the mug itself is dishwasher-safe in terms of material, the high heat and harsh detergents in a dishwasher can gradually fade the artwork over time. Hand washing gives you control over the temperature and cleaning method, helping the print stay vibrant for years.
Frequently Asked Questions
Can I put the mug in the dishwasher?
The ceramic body can technically go in the dishwasher, but the printed design is not guaranteed to withstand repeated high-heat cycles. For long-lasting artwork, hand washing is safer. Stick to hand washing for best results.
What should I use to clean the mug?
Use a soft sponge or cloth with mild dish soap. Avoid steel wool, abrasive pads, or bleach-based cleaners, as they can scratch or strip the print. Soft sponge + mild soap = safe cleaning.
How do I remove coffee or tea stains?
Make a paste of baking soda and water, gently rub the inside with a soft sponge, then rinse thoroughly. Do not use harsh chemical stain removers. Baking soda paste works well without damaging the mug.
Can I microwave the mug?
The ceramic material is microwave-safe, but the printed area may heat unevenly. To protect the design, limit microwave use and avoid sudden temperature changes. Use cautiously; hand-warm liquids only.
How should I store the mug?
Store in a dry cupboard away from direct sunlight. Stacking other mugs inside can scratch the print, so place it separately or with a soft cloth between items. Store separately to avoid scratches.
