A somewhat disgusting truth? The average reusable water bottle is teeming with bacteria. Reports vary (and different styles of water bottle tend to attract and trap different amounts of bacteria), but needless to say, cleaning your water bottle regularly should be a priority. That's why the best dishwasher-safe water bottles are a fantastic investment, and are made with dishwasher-safe materials that are effortless to clean.
First things first, you want to decide: glass, plastic, or stainless steel. There are perks and drawbacks to all three. A reusable glass water bottle is usually easier to spot when it needs to be cleaned (clear glass will show dirt or grime), but is also more breakable and doesn't regulate temperatures as well as an insulated bottle. Plastic, on the other hand is super durable, but you also have to take extra caution to wash it out and let it dry completely to prevent mold from building up and it also doesn't tend to offer insulation. And, stainless steel usually will do the best job of keeping cold water cold, but tends to be opaque, making it harder to spot when it needs to be cleaned.
You'll also want to pay mind to the top. The debate on straw versus no straw is ongoing, and you'll want to ensure the top of your water bottle is compatible with the way you prefer to sip your liquids. You'll also want to consider the size and shape of the water bottle, to make sure it cooperates with your lifestyle and cupholders. Ultimately, the best choice for you will depend on your personal preference and what you need it for.

1. The Overall Best Glass Water Bottle
- Available sizes: 12, 22, 32 ounces
This dishwasher-safe glass water bottle has a glass body surrounded by a silicone sleeve that protects it a bit from unexpected drops (but it's not unbreakable).

And, convenient time markers are printed on the sleeve to encourage you to drink more. Designed with a stainless steel twist lid, this bottle comes without a straw. When you're ready to clean it, simply slip off the silicone sleeve and put the rest in the dishwasher. This bottle comes in four different colors and three different sizes.

And because it has a slim design that's one of the smaller ones on this list, it can fit into virtually any cupholder.

According to one reviewer: "I got the bottle a couple of weeks ago and it is easy to hold. Very handy with a practical handle and useful flip-lid.The material is the best because it has no smell at all and can be used in dishwasher. Many of these bottles smell of plastic.
