Using your Dirty Diesel Big Swig water bottle is super easy. Just unscrew the leak - proof cap, fill it with your favorite drink, and screw the cap back on tightly. You can carry it around with you all day, thanks to its large 1240ml or 42fl oz capacity. The grippy bottom ensures it won't slide off surfaces. When it comes to cleaning, you can use mild dish soap and warm water. Avoid using abrasive cleaners as they might damage the powder coat finish. Also, make sure to dry it thoroughly before storing to prevent rust. That's all you need to know to enjoy your water bottle for a long time!
