Quick answer
Rinse your silicone straw set immediately after use, deep clean weekly with mild soap and a brush, and always dry completely before storing to prevent mold and odors.
Why silicone straws need special care
Silicone is soft and flexible, which makes it gentle on teeth and glass bottles, but its surface can trap oils and bacteria if not cleaned properly. Unlike metal or hard plastic, silicone can also absorb flavors and odors from coffee, tea, or smoothies over time. A consistent cleaning routine keeps your straws tasting neutral and looking like new.
The custom silicone straws designed for bkr bottles are made to fit snugly into the Straw Cap or Cup Cap. Because they create a seal, any residue left inside can lead to mold growth in the valve area. That’s why thorough drying is just as important as washing.
What you’ll need
A narrow bottle brush or straw cleaning brush, mild dish soap, warm water, and a clean dish towel or drying rack. Avoid abrasive sponges or bleach, which can degrade silicone over time.
Step-by-step silicone straw care routine
- Rinse immediately after use: Hold the straw under warm running water for 10–15 seconds to flush out milk, juice, or other residue before it dries and sticks. Use your thumb to block one end and create pressure for a more thorough rinse. Don't let a used straw sit on the counter; dried residue is much harder to remove.
- Deep clean with soap and a brush: Once a day (or after every use if you drink anything other than water), squirt a drop of mild dish soap into the straw, then run a narrow brush through the entire length. Scrub both ends and the outside. Rinse thoroughly until no suds remain. Skipping the brush can leave a thin biofilm inside that causes odors over time.
- Sanitize weekly (optional): For an extra-deep clean, soak the straws in a mixture of equal parts white vinegar and warm water for 15 minutes, then rinse well. Alternatively, boil them for 5 minutes — silicone can handle the heat without melting. Do not use bleach or hydrogen peroxide; they can break down silicone and leave a chemical taste.
- Dry completely before storing: Shake off excess water, then stand the straws upright in a drying rack or lay them on a clean towel. Make sure the inside is fully dry — you can blow through them or use a straw drying rack. Never store wet straws in a sealed bag or drawer. Moisture trapped inside is the #1 cause of mold in reusable straws.
- Store in a clean, dry place: Keep your straw set in a breathable container or a dedicated straw pouch. If you use the bkr Straw Cap, remove the straw after each use and store it separately so the cap’s valve can dry too. Storing straws inside a closed bottle with residual moisture invites mildew in the cap seal.
