tumbler

Hand-wash only is strongly recommended — dishwashers generate high heat, harsh detergents, and pressurized sprays, which can damage the sublimation prints, coatings, or seals.
Disassemble lids, gaskets, straws, and other components for better cleaning access.
Use a bottle brush or soft brush to reach the bottom and curves.
Rinse thoroughly and allow all parts to air-dry before reassembling.
Occasionally, for deep-cleaning odor or residue, combine baking soda + vinegar or use mild citric acid. Swirl, let fizz, rinse.

These tumblers are typically designed to hold both hot and cold beverages.
Pre-warm (or pre-chill) the tumbler by adding hot (or cold) water for a minute before pouring in your drink to maintain temperature performance.
Avoid carbonated drinks, which may build pressure and cause leakage or popping.

Avoid using in dishwasher, especially on “sanitize” or “high heat” cycles.
Don’t use bleach, strong detergents, or chlorine-based cleaners.
Do not use abrasive scrubbers or sharp scouring materials, as they can scratch the surface or wear off printed designs.

general

Always wash before first use with warm, soapy water, then rinse thoroughly.
Use mild dish soap and non-abrasive sponges or cloths.
Avoid harsh or abrasive cleaners, bleach, scouring pads, or strong chemicals.
Do not soak for long periods—especially lids or parts with decals.
Dry completely before storing. Moisture trapped in lids or seals can promote mold or odor.
Avoid exposing the drinkware to extreme temperature changes (e.g. pouring boiling water into a frozen cup).
Do not use metal utensils or sharp objects inside — they may scratch the surfaces and designs.

Wash by hand or dishwasher-safe depending on manufacturer labeling (many Libbey glass cups are dishwasher safe).
Use warm water and mild dish soap.
Avoid sudden temperature shifts (e.g. pouring boiling water into a very cold glass) to reduce risk of cracking.
Inspect rims and glass edges before use — chips can worsen over time.
Store carefully to avoid knocks or stacking too tightly.

Many are dishwasher-safe, but to preserve colorful prints or special finishes, hand-wash is preferred.
Use non-abrasive sponge/cloth and mild soap.
Avoid droppings or impacts—ceramics chip or crack.
For mugs with thermochromic or color-changing coatings, avoid prolonged dishwasher cycles or high-heat exposure. Some manufacturers recommend hand-washing to maintain the effect.
Microwave-safe depends on the mug — check manufacturer specs. Some mugs with metallic or specialty coatings may not be microwave-safe.

These require extra care to maintain both the glow effect and the design integrity.

Best Practices:

Hand wash only with mild soap and lukewarm water. Avoid dishwashers and high-heat cycles.
Use soft sponges or microfiber cloths — do not use rough scrubbers or brushes that can scratch the glow surface.
Avoid soaking or submersion for prolonged periods, especially on lids or areas with glow coatings.
Do not expose to direct, intense sunlight or UV light for long durations when stored — UV can degrade or bleach the glow pigments over time.
Avoid high-temperature fluids or excessive heat — heat may affect the glow layer over time.

Tips for Longevity:

Before storing at night, rinse and dry thoroughly to prevent residue buildup.
When recharging glow (if applicable), use a UV or bright light source briefly.
Handle with care — avoid drops or scratches to maintain clarity of the glow surface.
