How to Clean Metal Straws

Why Metal Straws Need Thorough Cleaning

Metal straws — usually stainless steel — are durable and reusable, but the narrow interior is impossible to clean without the right brush. Residue from smoothies, juices, and coffee builds up inside and can harbor bacteria if not cleaned after every use.

What You'll Need

• Dawn Platinum Dish Soap
• Cup lid gap cleaning brush set (includes straw brushes)
• Bottle Bright cleaning tablets
• White vinegar
• Baking soda

Daily Cleaning After Every Use

1. Rinse the straw immediately after use under running water — push water through the straw to flush out residue
2. Add a drop of dish soap to the straw brush from your cleaning brush set
3. Insert the brush and scrub the full length of the straw, twisting as you go
4. Rinse thoroughly under running water, pushing water through the straw
5. Air dry standing upright or on a clean surface — make sure the interior dries completely

Deep Cleaning: Bottle Bright Method

1. Place metal straws in a tall glass or container of warm water
2. Drop in one Bottle Bright tablet
3. Let soak 15–20 minutes — the effervescent action cleans inside the straw
4. Rinse thoroughly and air dry

Removing Stains and Odors

For stubborn stains or odors inside metal straws, soak in equal parts white vinegar and water for 30 minutes, then scrub with the straw brush and rinse. For mineral deposits, the vinegar soak dissolves them effectively.

Are Metal Straws Dishwasher Safe?

Most stainless steel straws are dishwasher safe, but the dishwasher doesn't clean the interior effectively. Always use a straw brush for the inside, even if you run them through the dishwasher for the exterior.

Final Thoughts

A straw brush from your lid gap cleaning brush set is essential for cleaning metal straws properly. Scrub after every use, rinse thoroughly, and do a weekly Bottle Bright soak to keep them hygienic and odor-free.
