Bottle Sterilizers, Dryers and Drying Racks (2026): What the CDC Actually Recommends

You may not need a bottle sterilizer. The CDC says sanitizing matters most for babies under 2 months, preemies and babies with weakened immune systems, that a hot dishwasher cycle with heated drying counts, and that 5 minutes in boiling water does the same job. Below is what the CDC says, then six sterilizers and steam bags and three drying racks compared against it.

How we chose: nine products sold by Amazon.com and in stock in September 2026, described from their listings and makers' claims (we did not test them), measured against the CDC's How to Clean, Sanitize, and Store Infant Feeding Items. We found no CPSC recalls of sterilizers or drying racks from these brands; Boon's June 2026 recall covers its NURSH 8 oz bottles, a different product from the Lawn rack here (CPSC notice).

When the CDC says to sanitize

The CDC separates cleaning (washing off milk and formula) from sanitizing (an extra step to kill remaining germs). On sanitizing, it says:

• "For extra germ removal, sanitize feeding items at least once daily. Sanitizing is particularly important when your baby is younger than 2 months, was born prematurely, or has a weakened immune system."
• "Daily sanitizing of feeding items may not be necessary for older, healthy babies, if those items are cleaned carefully after each use."
• "If you use a dishwasher with hot water and a heated drying cycle (or sanitizing setting) to clean infant feeding items, a separate sanitizing step is not necessary."

Sanitizing only works on items that are already clean. The CDC says to clean feeding items, bottle brushes and wash basins first, then sanitize everything, "even the bottle brush and wash basin."

Key point: if your dishwasher has a heated drying or sanitize cycle and your bottles are dishwasher-safe, you may not need a sterilizer at all.

The CDC's three ways to sanitize

The CDC lists three and says to check with the item's manufacturer about which to use:

1. Boil. Put disassembled items in a pot, cover with water, bring to a boil and "Boil for 5 minutes." Remove with clean tongs.
2. Steam. "Place disassembled items in microwave or plug-in steam system and follow the manufacturer's instructions for sanitizing, cooling, and drying the items." Every sterilizer and bag here works this way, and the CDC adds that if you steam an item, "be sure the entire item fits in the steamer."
3. Bleach, if you can't boil, steam or use a dishwasher. Mix "2 teaspoons of unscented bleach per gallon (16 cups) of water," submerge everything with no air bubbles, soak for at least 2 minutes, and don't rinse. The CDC says any remaining bleach "will break down quickly as it dries and will not hurt your baby."

Electric sterilizers

If you sanitize daily and want drying built in: the Dr. Brown's All-in-One steams and dries six bottles. The Baby Brezza Advanced holds eight bottles and two full pump part sets and dries with HEPA-filtered air, per the brand. Baby Brezza says contents stay sterile for 48 hours inside, and Dr. Brown's says up to 24 hours with the lid shut; those are the makers' claims.

If you will air-dry anyway: the Dr. Brown's Deluxe and Chicco 3-in-1 steam without a dryer, and the Chicco also works in the microwave, per the listing.

Steam sterilizers leave mineral scale on the heating plate; Baby Brezza tells owners to descale regularly, so check your model's manual for the method.

Microwave steam bags

The Medela Quick Clean bags (12 per box) and the reusable Dr. Brown's silicone bag use your microwave to make steam. Medela says each bag can be reused up to 20 times and cleans pump parts in 3 minutes. Dr. Brown's says to add 2 oz of water, microwave for 3 minutes in a 700 to 1250 watt microwave, and let the bag sit 10 minutes before handling. Follow the maker's steps exactly, since the CDC's steam method depends on them.

Bags suit pumping at work, travel, and the occasional sanitize once your baby is older and healthy.

Drying: a clean towel may beat a rack

The CDC says to "Allow to air dry thoroughly," on "a clean, unused dish towel or paper towel in an area protected from dirt and dust," and warns: "Do not use a dish towel to rub or pat items dry because doing so may transfer germs to the items."

On racks it says: "Air-drying infant feeding items on a clean dish towel or paper towel is probably more hygienic than using a drying rack. Drying racks may trap moisture, allow mold and germs to grow, and be difficult to clean."

If you use a rack, the CDC says to keep it for your baby's feeding items only and, every few days (or at least daily if your baby is under 2 months, premature or has a weakened immune system), "wash it, sanitize it, and allow it to dry thoroughly."

Fewer parts means less to scrub. The Boon Lawn splits into two pieces with a removable tray that Boon says is antimicrobial. The OXO Tot holds eight bottles over a drain board. The Munchkin holds the most, 16 bottles, but has the most pegs to wash.

Pro tip: with a sanitizing dishwasher, a rack or clean towels is all you need. For a newborn, a preemie or a pumping parent, a sterilizer dryer saves boiling every day.

Storing clean bottles

Once everything is completely dry, the CDC says to wash your hands, reassemble the parts and store them "in a clean, protected area such as inside a closed kitchen cabinet that is used only to store clean dishes." Items stored damp can grow mold.

Frequently Asked Questions

How long do I need to sterilize baby bottles?

The CDC gives no age cutoff. It says sanitizing is particularly important when your baby is younger than 2 months, was born prematurely or has a weakened immune system, and that daily sanitizing may not be necessary for older, healthy babies if items are cleaned carefully after each use. Ask your pediatrician about your baby.

Does the dishwasher sterilize bottles?

It can replace sanitizing: the CDC says a dishwasher with hot water and a heated drying cycle (or sanitizing setting) makes a separate sanitizing step unnecessary. Check that your bottles and parts are dishwasher-safe.

How long do you boil bottles to sterilize them?

Five minutes. The CDC says to put disassembled items in a pot, cover them with water, bring it to a boil, boil for 5 minutes, and remove the items with clean tongs.

Should I towel-dry baby bottles?

No rubbing or patting. The CDC says to let them air-dry thoroughly on a clean, unused dish towel or paper towel, because rubbing or patting with a dish towel may transfer germs.

Are drying racks bad for baby bottles?

Not bad, but the CDC says a clean towel is probably more hygienic, because racks may trap moisture, let mold and germs grow, and be hard to clean. If you use one, keep it for feeding items only and wash and sanitize it every few days, or daily for babies under 2 months, preemies or babies with weakened immune systems.
