Quick Answer

Clean your child's trainer cup daily by disassembling all parts and washing them in warm soapy water or the dishwasher. Pay special attention to the 360° valve and spout to prevent mold and keep the cup leakproof.

Why Regular Cleaning Matters

Kids' trainer cups collect milk, juice, and water residue that can quickly grow bacteria and mold if not cleaned properly. The 360° drinking rim and silicone valve are especially prone to trapping liquid, so thorough daily cleaning is essential for your child's health.

Regular care also extends the life of the cup. A well-maintained trainer cup stays leakproof longer, saving you money and reducing waste. The Mepal Mio 360° trainer cup is designed for easy cleaning, but even the best design needs the right routine.

Common Cleaning Mistakes to Avoid

Many parents assume a quick rinse is enough. Milk residue can cling to the valve and rim, leading to sour smells and mold. Always disassemble the cup completely before washing.

Another mistake is using abrasive sponges or harsh chemicals. These can scratch the plastic and damage the silicone seal, causing leaks. Stick to soft sponges and mild dish soap.

Step-by-Step Cleaning Routine

  1. Disassemble Completely: Separate the cup body, 360° drinking rim, silicone valve, and lid. Remove the valve from the rim by gently pulling it out. Common mistake: leaving the valve attached traps liquid and leads to mold. Always remove it.
  2. Rinse Immediately After Use: Rinse all parts under warm running water to remove leftover milk or juice. This prevents residue from drying and sticking. Checkpoint: if the cup sat for more than an hour, soak parts in warm soapy water before scrubbing.
  3. Wash with Warm Soapy Water: Use a soft sponge and mild dish soap to clean each part. Pay extra attention to the valve's inner flaps and the rim's drinking channel. Common mistake: using a bottle brush too aggressively can tear the silicone valve. Use a soft brush or your fingers.
  4. Dishwasher Option (Top Rack Only): Place all parts on the top rack of the dishwasher. Use a gentle cycle and avoid high heat to preserve the silicone seal. Checkpoint: do not place the cup on the bottom rack near the heating element—heat can warp the plastic.
  5. Air Dry Completely Before Reassembling: Lay all parts on a clean drying rack or towel. Allow them to air dry fully before putting the cup back together. Common mistake: reassembling while damp traps moisture and encourages bacterial growth. Wait until every part is bone dry.
  6. Inspect the Valve and Seal Weekly: Check the silicone valve for tears, stretching, or discoloration. Replace it if you notice any damage to maintain the leakproof seal. Checkpoint: a worn valve is the most common cause of leaks. Replace it every 2-3 months or sooner if needed.
