CIDYAUST P0403 10-Inch Straw Cleaning Brushes, 4-Pack with Nylon Bristles

After a smoothie or a day out with a reusable tumbler, a long brush makes it easier to clean the inside of a straw. The CIDYAUST P0403 set includes four 10-inch brushes for reusable straws and other narrow drinkware parts.

Spiral nylon bristles reach along the straw’s interior, while the flexible stainless steel core helps the brush follow curved straws. A soft silicone tip is designed to protect the surface as you clean.

Use them for Stanley cup straws, water bottles, baby bottles, silicone tubes and other narrow items. The hanging loop makes each brush easy to store between cleaning sessions.

Key takeaways

Each brush combines PA6 nylon bristles with a 304 stainless steel core. The bristles are arranged in a spiral to scrub around the inside of a straw, and the flexible design helps when cleaning curved tubes. A soft silicone tip helps protect the surface at the end of the brush.

The set contains four reusable brushes, so you can keep one near the kitchen sink and store the others with your drinkware or cleaning supplies. Their 10-inch length is intended to reach into deep cups and longer straws. When you’re finished, rinse a brush with water or put it in the dishwasher for cleaning. The hanging loop also gives you a simple way to keep it accessible and allow it to dry.

Buyers often describe the brushes as straightforward to use for routine straw cleaning, and some mention a snug fit in Stanley straws. These are customer impressions rather than a substitute for choosing a brush that suits the straw opening.

Quick sizing guide

The brushes are 10 inches long and have a 0.4-inch diameter. The product is described for use with 20 oz, 30 oz and 40 oz Stanley cups, including their straws. The length is useful when a straw or tube extends well into a deep tumbler, the bristles work against its inner surface as you move and rotate the brush. For narrower drinkware parts, match the brush diameter to the opening before use.

Who it’s for

It’s a good fit if you use reusable straws and want a dedicated tool for cleaning inside them, rather than relying on a cloth or a general-purpose bottle brush. The four-piece set also suits households that regularly wash water bottles, baby bottles or other narrow tubes. At home, at the office or while camping, the long handle helps reach into drinkware that is awkward to clean from the opening alone.

The brushes can also be used for hummingbird feeders and other suitable narrow items. For these jobs, the same practical combination applies: a long reach, spiral nylon bristles and a flexible core. Compared with a shorter brush intended for small, straight straws, this 10-inch format is designed to reach farther into deeper cups and curved straws.

Buying verdict

Choose the CIDYAUST P0403 set for a reusable straw-cleaning tool that pairs a long reach with flexible construction and a protective silicone tip. Four brushes make it practical to keep a cleaner close to the drinkware you use most, while the hanging loops support tidy storage. It’s a useful choice for regular care of tumbler straws, bottles and other narrow tubes.
