Which baby bottle brushes are best?

One of the biggest hygiene problems with infants is the baby bottle — old milk and other gunk builds up in the crevices, the nipple and at the bottom, which leads to bacteria growth and potential health problems for the baby.

That’s where baby bottle brushes come in. Baby bottle brushes like Dr. Brown’s Deluxe Bottle Brush are effective because they reach all the way down to the bottom of small bottles and gently clean them.

What to know before you buy a baby bottle brush

Some designs work better for some bottles

Before choosing a baby bottle brush, double-check the size and shape of the baby bottles you primarily use. Avoid getting a regular bottle brush, since these are usually designed to clean larger containers like jars or water bottles. These brushes are often too large or stiff to be suitable for baby bottle cleaning.

Different bottle brushes come in different widths, lengths and materials. A straw brush can clean out long, narrow plastic straws and usually has stiffer bristles. A miniature brush is perfect for smaller baby bottles with a tapered opening because they have shorter bristles. And nipple brushes have a special design to clean the hard-to-reach areas in the baby bottle’s nipple. Some of these brushes come with bristles on one end, while others have a molded tip.

It might have other uses

Since baby bottle brushes normally have more delicate bristles than other bottle brushes, they are also effective at cleaning other glassware. This includes champagne flutes, wine bottles and even small home appliances or aquariums.

Sets vs. individual brushes

Baby bottle brushes come individually packaged and in sets. Most individual brushes serve a specific purpose. Sets often include a variety of brush styles for cleaning different types of baby bottles. Even with sets, many people tend to have a preference of one or two brushes over the others.

What to look for in a quality baby bottle brush

Bristle material

Most baby bottle brushes are made from nylon, silicone or polyester, but what matters most is the material of the bristles. The most common material for bristles is nylon due to its strength and stiffness. This can be good if you need something a little abrasive, but it can also scratch more fragile bottles.

Silicone bristles, meanwhile, are softer and more flexible than nylon. This makes them ideal for cleaning delicate items. Silicone also usually lasts longer than other materials, but such brushes do require thorough, gentle cleaning.

Finally, there are polyester brushes. These are less common, but are still highly effective at cleaning bottles without damaging them. Instead of the standard bristles, these brushes usually have a scrubber or handle.

Brush handle

The handle of most baby bottle brushes is made from plastic, silicone or wire. Some come with an ergonomic grip to allow for easier handling, but this isn’t common. When looking for a good bottle brush, look for a handle with a good amount of flexibility so the brush can reach all the corners inside the bottle.

Bristle size and placement

In general, bristles that are less than one inch in length are more rigid than longer bristles, and are thus better at scrubbing and removing buildup in the bottle. Brushes with too few bristles or with bristles located along the handle can be useful for cleaning along the sides of bottles.


Some baby bottle brush sets come with a traveling case, a caddy for counter storage or a drying rack. If you travel or don’t want to buy all baby bottle brush items separately, consider purchasing a set.

How much you can expect to spend on a baby bottle brush

On the low end, expect to spend around $4-$10 on a baby bottle brush or small set of brushes. For a larger set, or if you’re looking for a specific high-quality brush, buyers may pay around $15.

Baby bottle brush FAQ

How often should I replace my baby bottle brush?

A. If you take care of your brushes and use them as intended, they should last a long time. However, it’s best to replace them every month or month and a half to avoid potential bacteria growth or worn-out bristles.

How can I clean a bottle brush?

A. Fill a sink with hot water and gentle liquid dish detergent. Place the bottle brushes in the water and let them soak for 30 minutes or so and then rinse. For newborns, pour hydrogen peroxide over the head and handle of the brush to kill any germs. Let it sit for 15 minutes, rinse and let it air-dry.

My baby bottles are dishwasher-safe. Do I still need a bottle brush?

A. Yes. Washing a bottle in a dishwasher may not clean every nook and cranny. If leftover formula or milk gets caked onto the base of the bottle, the dishwasher may not be able to get it off. Additionally, if you plan to travel, a couple of baby bottle brushes can be handy.
