| Common uses | Drinking coffee, tea, and water at home or outdoors; a mug may also be used to warm a beverage when its maker permits direct heating. | Check the product instructions first. Mugs differ in construction, handles, coatings, and intended use. |
| Food contact | Use a mug specifically sold and maintained for food and beverage contact. | Titanium is generally corrosion-resistant, but the material grade, surface finish, welds, and any coating can affect suitability. Follow the maker’s food-contact guidance. |
| Microwave use | Do not put a titanium mug in a microwave. | Metal can reflect microwave energy and may cause arcing or damage to the appliance. |
| Heating on a stove or flame | Heat the mug only if the manufacturer explicitly says it is suitable for stovetop or flame use. | Thin metal can heat quickly and unevenly. A handle may become hot, and an empty mug can overheat. Use a stable heat source and heat-resistant protection. |
| Handling hot drinks | Hold the mug by its handle, if provided, and set it on a stable, heat-resistant surface. | A single-wall metal mug does not insulate like a double-wall cup. Its sides and rim can become hot; allow hot beverages to cool before drinking. |
| Routine cleaning | Wash with warm water, mild dish soap, and a soft sponge or cloth; rinse thoroughly and dry. | Prompt washing helps prevent coffee or tea residue and water spots. Follow product instructions if the mug has a special finish or coating. |
| Stubborn residue | Soak with warm, soapy water, then clean gently with a non-abrasive sponge. | Avoid steel wool, harsh scouring powders, and abrasive pads that can scratch or dull the surface or damage a coating. |
| Dishwasher use | Use a dishwasher only when the product instructions confirm that the mug is dishwasher-safe. | Decorative finishes, coatings, attached parts, or other construction details may not tolerate repeated dishwasher cycles. |
| Chemical cleaners | Use ordinary dish soap for routine cleaning. Rinse well after any approved cleaning product. | Avoid prolonged exposure to bleach or chlorine-based cleaners, which can be corrosive to metals. Never mix cleaning chemicals. |
| Storage and inspection | Store the mug clean and dry. Inspect it periodically for dents, sharp edges, loose handles, or damaged coatings. | Stop using it if damage creates a cut hazard or if a coating is peeling or flaking into the drink. |
