Product Care

SPILE flasks are intended to be your long-term partner in hydration. To maintain its design and function, follow the simple steps below.

Before Initial Use

SPILE flasks are to be cleaned by handwashing only. Prior to your first use, handwash your flask and cap with warm, soapy water. Rinse both of them afterward and let it air-dry.

What to do
  • Use a bottle brush frequently to clean your flask thoroughly.
  • Use white distilled vinegar to remove any discoloration or stains on the inside of your flask. Put ½ cup of white distilled vinegar in your flask, swirling it around to reach the affected areas, then let it sit for 5 minutes. Rinse thoroughly with warm water and air-dry.
  • Use baking soda to remove stubborn spots inside your flax. Make a paste consisting of 2-3 tablespoons of baking soda and a small amount of warm water. Use a bottle brush to spread the paste inside your flask and let it sit for 15 minutes. Rinse with hot water afterward and let it air dry.

What not to do
  • Do not put clean your flask through the dishwasher or soak the exterior in hot water. Repeated exposure to hot temperatures can cause discoloration in the powder coat of the flask. If it needs cleaning, handwashing is the best option.
  • Do not put your flask in the freezer. Due to its ThermaShield Technology, drinks inside the flask will be protected from the outside temperature. Thus, it will not freeze even if it's in the freezer. If you want your drinks colder, SPILE flask's wide mouth can accommodate ice cubes!
  • Do not put your flask on the stove or on the grill. Due to its insulating properties, your drink's temperature will not be influenced by the outside temperature. If the flask is put on any source of heat, the extreme temperature will damage the outside of the flask.
  • Do not use chlorine or bleach to clean your flasks. These strong chemicals can ruin and rust the stainless steel; thus, they should not be used nor applied to your flasks.
