How to Clean the Stanley Yerba Mate Bombilla Straw

Quick Answer

To clean your Stanley Yerba Mate Bombilla Straw, rinse it immediately after use, then soak and scrub with a small brush to remove yerba mate residue and keep the filter unclogged.

Step-by-Step Cleaning Guide

1. Rinse Immediately After Use: Hold the bombilla under warm running water for 10–15 seconds, rotating it to flush out loose leaves and residue from both ends. This prevents debris from drying and sticking inside the filter. Don't let the bombilla sit with dry leaves—rinsing right away makes every later step easier.
2. Soak to Loosen Stubborn Residue: Fill a small cup or bowl with warm water and a drop of mild dish soap. Submerge the bombilla completely and let it soak for 5–10 minutes. This softens any dried-on tannins or oils. Avoid using boiling water or harsh chemicals—they can damage the stainless steel finish over time.
3. Scrub the Filter and Straw: Use a narrow bottle brush or a dedicated straw cleaning brush to gently scrub the inside of the straw. For the spoon-shaped filter, brush both sides carefully to dislodge particles trapped in the slots. Rinse thoroughly under running water. A pipe cleaner or thin craft brush works well if you don't have a straw brush—just make sure it's soft enough not to bend the filter slots.
4. Dry Completely Before Storing: Shake off excess water and place the bombilla upright in a drying rack or on a clean towel. Allow it to air dry completely for at least an hour before storing it in a drawer or your mate kit. Storing a damp bombilla can promote mold growth inside the straw—always confirm it's bone dry.
