Product Care & Cleaning Guide Page
Thank you for purchasing the AI Master Double-Wall Stainless Steel Bamboo Tea Infuser Tumbler. Crafted with a 100% natural bamboo exterior and premium food-grade 18/8 (304) stainless steel interior, your tumbler is designed to provide years of dependable temperature retention with proper care.
Because bamboo is an authentic organic material, following these care and cleaning guidelines will protect its natural beauty and preserve its vacuum insulation.
Initial Use: First-Time Cleaning
Before using your tumbler for the first time:
- Disassemble all components: the bamboo tumbler body, the two-piece stainless steel infuser basket, and the lid.
- Wash the stainless steel interior and infuser basket thoroughly with warm water and mild dish soap.
- Gently wipe the exterior bamboo and lid with a damp, soft cloth.
- Rinse the interior thoroughly and allow all parts to air-dry completely with the lid off.
Daily Cleaning & Washing Instructions
1. The Bamboo Exterior & Lid (Hand-Wash Only)
- Never place in a dishwasher: High heat, aggressive detergents, and pressurized water cycles will strip the protective seal and cause natural bamboo to warp, split, or discolor.
- Do not soak or submerge: Never submerge the tumbler in a sink of water. Excess water immersion degrades natural wood fibers.
- Wipe clean: Simply wipe the bamboo exterior clean using a soft sponge or cloth with warm water and mild dish soap, then dry immediately with a clean towel.
2. The Stainless Steel Interior & Infuser Basket
- The food-grade 18/8 (304) stainless steel interior resists rust, stains, and flavor retention.
- Rinse with warm soapy water after every use using a soft bottle brush or non-abrasive sponge.
- The two-piece stainless steel infuser basket can be separated and rinsed under running water to clear out loose tea leaves or fruit remnants.
3. The Silicone Leakproof Gasket
- The lid features a removable, food-grade BPA-free silicone sealing ring.
- Gently remove the silicone ring once a week for a thorough rinse to prevent tea residue or moisture buildup. Ensure it is completely dry before reseating it into the lid groove.
Deep Cleaning & Stain Removal Tips
Over time, dark teas or coffee can leave natural tannin stains on the interior stainless steel. To restore your tumbler's interior shine without harsh chemicals:
- Baking Soda Method: Add 1 to 2 tablespoons of baking soda into the tumbler, fill with warm water, and let sit for 20–30 minutes. Gently scrub the interior with a soft bottle brush and rinse thoroughly.
- Vinegar Rinse: For stubborn mineral buildup, fill the tumbler with equal parts warm water and distilled white vinegar. Allow it to soak for 15 minutes, rinse thoroughly with fresh water, and let air dry.
Maintaining the Natural Bamboo Luster
To keep the natural bamboo casing looking rich and hydrated, apply a few drops of food-grade mineral oil, organic coconut oil, or cutting board conditioner to the bamboo surface every few months using a soft cloth. Let it absorb for 15 minutes and buff away any excess.
Important Safety & Usage Precautions
- Do NOT Microwave: The tumbler contains double-wall vacuum stainless steel and must never be placed in a microwave or conventional oven.
- Do NOT Freeze: Freezing liquids expand and can damage the vacuum seal between the steel walls.
- Hot Liquids Caution: The double-wall insulation keeps beverages piping hot for up to 12 hours. Always test temperature before drinking and exercise care when opening the lid to avoid steam or hot splashes.
- Keep Dry When Stored: Always store your tumbler with the lid off to allow proper airflow and prevent moisture retention.
