Got a dirty reusable straw but no cleaning brush? Don’t panic. You can get your straw perfectly clean using items you already have at home. I’ve tested countless methods, and these three consistently deliver the best results without any fuss.
After trying everything, I’ve narrowed it down to three methods that work every single time. They’re simple, use common household items, and handle everything from smoothie residue to coffee stains.
Method 1: Dish Soap and Hot Water Soak
This is your bread-and-butter technique. Simple, effective, and works for 90% of cleaning situations.
Best for: Daily cleaning, light residue, most liquids including smoothies, juices, and coffee drinks.
Hot water dissolves sugars and oils while soap breaks down proteins and fats. The soaking time lets the solution work its way into every crevice.
What you need:
- Liquid dish soap
- Hot tap water
- A tall glass or jar
Step by step:
- Fill a tall glass with hot water (hot enough that you can still touch it)
- Add 3-4 drops of dish soap
- Drop your straw in and make sure it’s completely covered
- Let it soak for 15-20 minutes
- Pull the straw out and run hot water through both ends
- Shake out the water and you’re done
Method 2: Baking Soda Power Clean
When soap isn’t cutting it, baking soda steps up. This method tackles tough stains and eliminates odors naturally. Baking soda is mildly abrasive and alkaline, which breaks down acidic stains and neutralizes odors. The shaking action scrubs the interior walls.
Best for: Coffee or tea stains, protein shake residue, anything with strong smells, and straws that haven’t been cleaned in a while.
You’ll need:
- Baking soda (1 tablespoon)
- Warm water
- A small spoon or your finger
Here’s how:
- Block one end of your straw with your finger
- Pour about 1 tablespoon of baking soda into the open end
- Add just enough warm water to make a thick paste inside the straw
- Cover the other end with your other finger
- Shake the straw like a maraca for 30 seconds
- Remove your fingers and let the mixture flow out
- Rinse with clean water until no residue remains

Method 3: White Vinegar Deep Clean
This is your heavy-duty option for when straws need serious attention or sanitizing. Vinegar’s acidity dissolves mineral deposits, kills bacteria, and breaks down protein buildup. It’s particularly effective against hard water stains.
Best for: Mineral buildup from hard water, sanitizing after illness, straws with persistent odors, and monthly deep cleaning.
Materials needed:
- White vinegar
- Water
- A container that fits your straw
The process:
- Mix equal parts white vinegar and water in a container
- Submerge your straw completely
- Let it sit for 30 minutes (longer for really stubborn buildup)
- Remove and rinse thoroughly with clean water
- Run additional water through both ends to remove any vinegar smell

Special Considerations for Different Straws
Stainless steel: All three methods work perfectly. These straws are practically indestructible.
Silicone: Can handle hot water and all cleaning solutions. Very forgiving material.
Glass: Be gentle when shaking with baking soda. Focus more on the soaking time than aggressive agitation.
Bamboo: Avoid extended soaking with vinegar. Stick to shorter cleaning times and dry immediately.
The Reality Check
Learning how to clean a straw without a straw cleaner doesn’t require special skills or expensive products. These three methods handle every situation I’ve encountered in years of using reusable straws.
Stick to soap and water for daily use, break out the baking soda for tough jobs, and use vinegar when you need serious cleaning power. That’s it. No complicated procedures, no weird household items, just reliable methods that work every single time.
Your straws will stay clean, your drinks will taste better, and you’ll never stress about not having a specialized cleaning brush again.
