21 oz. Standard Mouth Bottle with Flex Cap

Materials: Metal, Plastic, Rubber

Origin: Imported

Care Instructions: Hand-wash your flask and cap with hot, soapy water. Rinse the flask as well as the cap, and it is ready for adventure. Wash your flask with a bottle brush. Shop cleaning accessories here and use the Bottle Brush and Straw and Lid Cleaning Set as frequently as possible. You can use household white distilled vinegar to help remove any stains or discoloration on the inside of your flask. Recommend putting the ½ cup of vinegar in your flask, gently swirling the vinegar around to wash any affected areas and let sit for 5 minutes. Rinse thoroughly with warm water and repeat if necessary. For those stubborn spots inside your Hydro Flask, mix 2-3 tablespoons of baking soda with a small amount of warm water to form a scrubbing paste. Dip the bristles of your bottle brush in the paste and work the paste into the affected area on the inside of your flask. Repeat as necessary until stain disappears. The Hydro Flip Lid and Wide Straw Lid are top-rack dishwashers safe. The cap may last longer if it is hand washed, but if it needs to be deep cleaned, the dishwasher is acceptable. The dishwasher can get hot enough to affect the insulation property of the flask as well as discolor the powder coat. Similarly, soaking your entire flask in hot water can discolor the powder coat. Due to the double wall vacuum insulation, the water inside will be protected from the temperature inside the freezer and won’t freeze. If you want to ice cold water, put some ice cubes inside your flask and notice how long it takes them to melt. Due to the double wall vacuum insulating property of the flask, the outside temperature will not change the inside beverage temperature. If you put your flask on any sort of stove or heat source, the heat will damage the outside of the flask. The flex cap, wide flat cap, flat cap, standard loop cap and narrow Loop cap can take on water when they are run through the dishwasher or submerged in water for an extended time. Recommend hand washing them with hot, soapy water, rinsing and allowing them to dry. Use bleach or chlorine to clean our products. Those chemicals will ruin and rust stainless steel, therefore they should not be used on our products.
