Quick Answer

Rinse your HydroJug straws with warm water immediately after each use, then wash them weekly with a bottle brush and mild soap. For stubborn residue or odor, soak the straws in a baking soda and vinegar solution for 15 minutes before scrubbing. This keeps the straws tasting fresh and prevents bacteria buildup.

Why Straw Cleaning Matters

HydroJug straws are designed for repeated use, but the narrow interior can trap milk, smoothie residue, or sugary drink particles. If not cleaned properly, these residues can develop odors or even mold over time. Regular cleaning preserves the taste of your water and extends the life of the straws.

The HydroJug 40oz Sport Straw Pack includes four BPA-free, dishwasher-friendly straws. While they can go on the top rack of a dishwasher, hand washing with a dedicated straw brush is more thorough and helps you see when the inside is truly clean.

What You’ll Need

A long, flexible straw cleaning brush (available at most kitchen stores or online), mild dish soap, baking soda, white vinegar, and a clean drying rack. Avoid using bleach or harsh chemicals that could damage the BPA-free plastic.

Step-by-Step Cleaning Routine

  1. Rinse Immediately After Use: Hold the straw under warm running water for 10-15 seconds, flushing water through both ends. This removes loose particles before they dry and stick. Common mistake: letting the straw sit with leftover drink inside. Even a short delay can make cleaning harder.
  2. Weekly Soap Scrub: Fill a cup with warm water and a few drops of mild dish soap. Dip the straw brush into the soapy water, then insert it into the straw. Push the brush back and forth several times, then rinse thoroughly with clean water. Checkpoint: hold the straw up to the light after rinsing. If you see any cloudiness or residue, repeat the scrub.
  3. Deep Clean for Odor or Stubborn Buildup: Mix 1 tablespoon of baking soda with 1/2 cup of white vinegar in a tall glass (it will fizz). Submerge the straws and let them soak for 15 minutes. Rinse with warm water, then scrub with the brush if needed. This method is gentle on the plastic but effective against coffee, tea, or smoothie stains. Do not use bleach.
  4. Air Dry Completely: After washing, shake off excess water and place the straws upright in a drying rack or on a clean towel. Allow them to air dry completely before storing them in a drawer or the straw pack. Trapped moisture inside a closed container can encourage mold. Drying fully is just as important as washing.
