Is It OK to Wash Baby Bottles in the Dishwasher? A Practical Guide
Learn whether you can safely wash baby bottles in the dishwasher, plus tips on safe detergents, rack setup, cycle choice, and best practices from Dishwasher Tips.
Yes, it can be okay to wash baby bottles in the dishwasher, but only under strict conditions. Confirm that all bottle parts are labeled dishwasher-safe, load bottles on the top rack in a dedicated basket, use a gentle or sanitize cycle, and choose a mild, baby-safe detergent. Do not run damaged parts, and always follow the manufacturer’s guidance.
How dishwashers handle baby bottles
Inside modern dishwashers, hot water and mechanical cleaning remove milk residue, then a sanitize phase can reduce potential germs. Baby bottles, nipples, rings, and caps come in different materials—plastic, silicone, and glass—so heat, detergents, and cycle length affect each part differently. According to Dishwasher Tips, whether you should run bottles through a dishwasher depends on the bottle’s material, the dishwasher model, and the exact cycle you select. Not all components are dishwasher-safe; nipples and small silicone parts can warp or crack if exposed to high heat or aggressive detergents. Before loading, read both the bottle maker’s guidance and your dishwasher’s user manual. If a component is labeled dishwasher-safe, you can proceed with careful top-rack loading and a gentle or sanitize cycle using a baby-safe detergent.

Tools & Materials
- Baby bottle rack basket(Use a dedicated basket or rack for bottles and nipples to keep parts separated and secure during washing.)
- Mild, baby-safe dish detergent(Choose a detergent formulated for baby bottles, free of harsh scents and additives.)
- Bottle brushes with flexible neck(Have a bottle brush and nipple brush on hand for pre-cleaning and post-wash inspection.)
- Dishwasher-safe nipples, rings, and caps(Only load parts that are explicitly labeled dishwasher-safe.)
- Heat-resistant tongs(Useful for safely handling hot items after the cycle.)
- Drying rack or clean towels(Air-dry or pat-dry bottles and parts after washing.)
Steps
Estimated time: 15-25 minutes
- 1
Check bottle parts for dishwasher-safety
Inspect every bottle, nipple, ring, and cap to confirm dishwasher safety. If any part lacks a clear label or shows wear, skip it in the dishwasher and wash by hand instead. This step reduces the risk of warping or cracking under heat.
Tip: If unsure, contact the manufacturer or keep a dedicated non-dishwasher set for travel and daycare use. - 2
Pre-rinse to remove milk residue
Rinse bottles and nipples under warm running water to loosen dried milk. Pre-cleaning reduces the burden on the dishwasher’s cycles and improves overall cleanliness.
Tip: Rinse away milk at the sink or with a spray bottle before loading. - 3
Load bottles on the top rack in a basket
Place bottles upside down in the top rack so water and detergent reach the interior. Use the basket to separate nipples and rings from the bottle body to prevent nesting or trapping residue.
Tip: Avoid stacking parts on top of each other; air must circulate for effective cleaning. - 4
Add detergent and select a gentle/sanitize cycle
Pour a baby-safe detergent into the dispenser and choose a cycle with a sanitize option or a gentle heat profile. If your dishwasher allows, enable a longer rinse to reduce soap residue on plastic.
Tip: Do not use hot-wash cycles meant for heavy cookware; they can degrade plastics. - 5
Run the cycle and cool before handling
Start the cycle and allow the dishwasher to complete its run. Let the rack cool briefly before removing parts to prevent burns and reduce the risk of warping from sudden temperature changes.
Tip: Use heat-resistant tongs or a dry rack mat to handle hot items. - 6
Inspect, dry, and store properly
After washing, inspect each piece for warping, clouding, or cracks. Dry with a clean towel or air-dry on a rack before storing away from contaminants.
Tip: If any part remains milky, cloudy, or discolored, replace it before next use.
