You’ve got a few handy options, and they’re easy to use.

• Straw cleaning brushes: Slim brushes sized for straws reach all the way through to scrub residue.
• Tube/pipe brushes: Similar tools with different diameters for narrow or wide straws.
• Bottle brush sets with straw tools: Many sets include a long bottle brush plus a separate straw brush, so you can clean lids and cups too.

Pair your brush with warm, soapy water. Choose a brush that fits your straw’s diameter and length so it glides through without forcing. A gentle pass from both ends can help lift buildup without scratching.

Walmart carries a range of straw cleaners online and in select stores.

• Single brushes and multi-packs: Options include assorted diameters and lengths for different straw sizes.
• Extra-long styles: Brushes around 8–10 inches for tall tumblers and bottles.
• Bundles and sets: Cleaning kits that combine bottle brushes with dedicated straw brushes; some include storage holders.

You can browse the Household Essentials/cleaning tools section to compare features. Depending on location, pickup and delivery options may be available. Product availability varies, so it’s a good idea to check the listing details for sizes, materials, and what’s included in each set.

1. Rinse first: Run warm water through the straw to loosen debris.
2. Soak briefly: Fill a cup with warm, soapy water and let the straw sit a few minutes.
3. Brush through: Choose a snug-fitting straw brush and gently push it through from both ends, rotating as you go. For narrow straws, use a thinner brush from a variety pack.
4. Focus on trouble spots: Pay extra attention to bends and the mouth end.
5. Rinse and dry: Flush with clean water and let the straw air-dry upright.

These steps can help lift residue without harsh chemicals. If your straw has specific care instructions, follow those for best results.

A straw cleaner is a slim brush designed to reach inside reusable straws and small drinkware channels.

• Deep cleaning: Its narrow shape gets where rinsing can’t, helping remove leftover liquids and residue.
• Versatility: Commonly used for straws in water bottles, tumblers, and sippy cups, and can also reach tight spots in lids and tubes.
• Practical sizing: Many are long enough for tall straws and come in multiple diameters to match different openings.

Using a straw cleaner with warm, soapy water can support more thorough cleaning between uses.

• Match the diameter: Pick a brush that fits snugly in the straw without forcing. Variety packs with multiple sizes help cover narrow and wide straws.
• Consider length: Choose a brush as long—or longer—than your straw. Many options are around 8–10 inches for tall drinkware.
• Check materials: Brushes often use nylon bristles on a flexible stainless steel core for balanced scrubbing and maneuverability.
• Think beyond straws: If you also clean bottles and lids, a set that includes a bottle brush plus straw brushes can be more convenient.
