Are Hydro Flask Bottles Dishwasher Safe?

Yes, Hydro Flask bottles are dishwasher safe. Their powder coated finish offers heat resistance to the drying cycles on most dishwashers, so feel free to put your bottle on the top rack to get clean. Of course, if you don't own a dishwasher, you can hand wash your Hydro Flask bottle as well. If you choose to hand wash your Hydro Flask, be sure to use warm, soapy water. You might also want to use the brand's bottle brush and Straw and Lid Cleaning Set to ensure that every nook and cranny of your bottle and its lid are clean.
Additionally, if you'd rather skip hand washing, you can use the Natural Cleaning Tablets to clean the inside of your bottle or tumbler. To get started, just fill the bottle with warm water, then drop in a single tablet per 32 ounces of water. Let the water stand for 15 to 30 minutes depending on the soil level, then rinse. However, you should not soak the entire bottle in water. Gently wipe down the exterior with warm, soapy water as needed and dry immediately.

Are Hydro Flask Lids Dishwasher Safe?

Yes! If you choose to wash your cap or lid in the dishwasher, place it on the top rack only. If you don't own a dishwasher or prefer to hand wash your items, that's also an option. Use warm, soapy water to clean—the brand officially recommends using the Straw and Lid Cleaning Set for best results. Additionally, Hydro Flask offers Natural Cleaning Tablets to clean their bottle accessories. Simply fill a large bowl with warm water, place your lids or other accessories in the bowl, and drop in one tablet per 32 ounces of water. Let the items sit in the mixture for 15 to 30 minutes, then rinse and let dry. If it's been a while since you washed your straw or lid, a deep cleaning is in order.

Are Hydro Flask Mugs Dishwasher Safe?

In short, Hydro Flask coffee mugs are not dishwasher safe. They do not have the same powder coated finish as Hydro Flask bottles and therefore cannot be put in the dishwasher. However, the cap or lid on your coffee mug is top rack dishwasher safe.

How Do I Clean Rust in My Bottle?

While stainless steel resists rust, it is not entirely rust proof; as such, there's a small chance you might see rust on your bottle or tumbler. If so, mix baking soda and vinegar to form a paste, then spread the mixture on the spot and let sit for 5 to ten minutes. Then, gently scrub the spot with a sponge or a bottle brush to remove the rust and leave your Hydro Flask looking good as new.

Cleaning Other Hydro Flask Items

Hydro Flask offers other items including insulated totes, insulated lunch boxes and bottle slings. All of these items should be cleaned with a damp cloth and air dried. For all of these products, avoid using harsh cleaning agents or chlorine bleach.

In Summary

While some Hydro Flask products are dishwasher safe, not all of them are. Be sure to get the most out of your cute new insulated cup or mug with the proper care, whether you're tossing it in the dishwasher or washing it by hand.
