Can You Put Bottles in the Dishwasher?
When it comes to kitchen cleanup, the dishwasher is a lifesaver for many. But a common question arises: *Can you put bottles in the dishwasher?* Whether it’s baby bottles, reusable water bottles, glass wine bottles, or plastic containers, the answer isn’t a simple yes or no. It depends on the type of bottle, its material, and the dishwasher’s settings. In this detailed guide, we’ll explore the ins and outs of washing bottles in the dishwasher, offer practical tips, and dive into related considerations to ensure your bottles come out clean, safe, and undamaged. Let’s break it down step by step.

Understanding Bottle Materials and Dishwasher Compatibility
The first thing to consider is the material of the bottle. Not all bottles are created equal, and dishwashers can be harsh environments with high heat, powerful water jets, and detergents. Here’s a breakdown of common bottle materials and their dishwasher compatibility:
Glass Bottles
Glass bottles, like those used for wine, beer, or sauces, are generally durable and heat-resistant. According to the experts at Good Housekeeping, “Glassware can typically go in the dishwasher, but avoid placing delicate or thin glass items in there, as they’re more prone to cracking under heat or pressure” [(( Good Housekeeping ))]. So, your average glass soda bottle or Mason jar? Usually dishwasher-safe. That said, always check for manufacturer markings—some glass bottles may have decorative coatings or labels that don’t hold up well in the machine.
Plastic Bottles
Plastic bottles, such as reusable water bottles or baby bottles, are trickier. The key is to look for a “dishwasher-safe” symbol (typically a small dish with water droplets) on the bottom. “Most modern plastic bottles, like those from brands such as Nalgene or CamelBak, are made from BPA-free materials like Tritan or polyethylene, and many are labeled dishwasher-safe,” notes REI’s blog on bottle care [(( REI Expert Advice ))]. However, older plastics or cheaper bottles might warp or leach chemicals when exposed to high heat. If there’s no label, it’s safer to hand-wash.
Stainless Steel Bottles
Stainless steel water bottles (think Hydro Flask or Yeti) are increasingly popular, but dishwasher compatibility varies by brand. Hydro Flask’s official stance is clear: “We do not recommend washing your Hydro Flask in the dishwasher as it can affect the powder coat finish and potentially compromise the vacuum insulation over time.” Instead, they suggest hand-washing with warm soapy water. Yeti, on the other hand, states that their Rambler bottles are dishwasher-safe, though they recommend the top rack to avoid dents from heavy items.
Baby Bottles
Baby bottles deserve special attention due to hygiene concerns. Dr. Brown’s, a leading baby bottle brand, assures parents that “All Dr. Brown’s bottles and most components are dishwasher-safe (top rack only), but hand-washing is recommended for longevity” [(( Dr. Brown’s FAQ ))]. Silicone nipples, however, often need hand-washing as dishwasher heat can degrade them faster. Always check the packaging—some brands like Philips Avent or Comotomo have specific instructions.

How to Safely Load Bottles in the Dishwasher
Assuming your bottle is dishwasher-safe, placement matters. Improper loading can lead to poor cleaning, damage, or even a mess in your machine. Here’s how to do it right:
1. Top Rack vs. Bottom Rack: Most bottles—especially plastic and delicate glass—should go on the top rack, where water pressure and heat are less intense. Stainless steel bottles might tolerate the bottom rack, but check the manufacturer’s advice first.
2. Secure the Bottles: Bottles can tip over during the cycle, trapping water or detergent. Use the dishwasher’s prongs or a specialized bottle holder (common for baby bottles) to keep them upright.
3. Separate Components: For bottles with lids, straws, or valves (like reusable water bottles or baby bottles), disassemble everything. “Place small parts in a mesh bag or the utensil basket to prevent them from falling to the bottom and melting,” advises The Spruce [(( The Spruce ))].
4. Avoid Overcrowding: Give bottles space for water and detergent to circulate. Crammed dishes mean dirty bottles.

Potential Risks of Dishwashing Bottles
Even if a bottle is labeled dishwasher-safe, there are risks to consider:
- Heat Damage: High-temperature cycles (like sanitizing modes) can warp plastic, crack thin glass, or weaken insulation in stainless steel bottles.
- Detergent Residue: Harsh detergents might leave a film or odor, especially on plastic. Opt for a mild, fragrance-free detergent if this is a concern.
- Label and Finish Wear: Printed labels or powder-coated finishes (common on stainless steel bottles) may fade or peel over time.
- Bacterial Growth: If bottles don’t dry completely—say, because they tipped over—moisture can linger, encouraging mold or bacteria. Running a heated dry cycle can help.

Alternatives to Dishwashing Bottles
If you’re unsure about putting bottles in the dishwasher or want to extend their lifespan, hand-washing is a reliable fallback. “Fill the bottle with warm water and a drop of dish soap, then use a bottle brush to scrub the interior,” suggests Wirecutter’s guide to cleaning water bottles. For stubborn residue (think dried milk in baby bottles or smoothie gunk), a mix of vinegar and baking soda works wonders—just rinse thoroughly after.
For sterilization, especially with baby bottles, boiling is an option. The CDC recommends placing disassembled bottles in boiling water for five minutes to kill germs, though this isn’t necessary after every use unless the baby is immunocompromised.

Special Cases and Tips
Vintage or Collectible Bottles
Got an antique glass bottle or a limited-edition beer bottle? Skip the dishwasher entirely. These items often have fragile labels or sentimental value that hot water and jets could ruin.
Bottles with Straws or Narrow Necks
Reusable bottles with straws (like those from Stanley or Owala) need extra care. Dishwasher heat can damage straws, so hand-washing with a straw brush is often best. Narrow-neck bottles might not get fully clean in the dishwasher—use a bottle brush for precision.
Eco-Friendly Considerations
Running a dishwasher uses less water than hand-washing a full load, according to Energy Star. If you’re washing multiple bottles, the dishwasher might be the greener choice—just ensure they’re safe to include.

Frequently Asked Questions (FAQ)
Q: Can I put any plastic bottle in the dishwasher?
A: No, only plastic bottles labeled “dishwasher-safe” should go in. Check the bottom for the symbol or consult the manufacturer. Unlabeled or thin plastics (like disposable water bottles) can melt or warp.
Q: Will the dishwasher sterilize baby bottles?
A: Most dishwashers don’t reach the 212°F (100°C) needed for true sterilization, though a sanitizing cycle gets close. For guaranteed sterilization, boil the bottles or use a dedicated sterilizer.
Q: Why do my bottles smell after the dishwasher?
A: This could be from detergent residue or trapped moisture. Use a milder detergent, ensure proper drying, and rinse bottles beforehand if they held strong-smelling contents.
Q: Can I dishwasher-clean bottles with stuck-on labels?
A: Yes, but it might not remove the label. Soak in warm soapy water first to loosen adhesive, then run them through the dishwasher for a thorough clean.
Q: Are stainless steel bottles always dishwasher-safe?
A: Not necessarily. Brands like Hydro Flask advise against it to protect insulation and finishes, while others like Yeti say it’s fine. Check the care instructions.

Conclusion
So, can you put bottles in the dishwasher? In most cases, yes—provided they’re made of dishwasher-safe materials like sturdy glass, certain plastics, or approved stainless steel, and you load them correctly. However, always double-check labels and manufacturer guidelines to avoid damage or health risks. For delicate, sentimental, or tricky-to-clean bottles, hand-washing remains a safe bet. With the right approach, your bottles can stay spotless and functional, whether they’re for hydration, feeding, or storage. Happy cleaning!
