Cleito tanks are a popular type of water bottle that come in many different colors and designs. They are perfect for taking a drink while you work or play, and they can also be used as a place to store water or juice. To clean the Cleito tank, you will first need to remove the top. This will allow you to access the cleaning material inside. Next, use a mild soap and water to clean the inside of the tank. Be sure to use plenty of soap because Cleito tanks can get dirty quickly. Finally, dry the tank completely by using a dryer sheet or an oven on high heat.
