How to Get Calcium Deposits Off a Hot Tub

A hot tub is a luxury item that can help relax your tired muscles at the end of a long day. Part of owning and maintaining a hot tub is keeping it clean. You may notice white, flaky deposits collecting on your hot tub over time. These flakes are calcium deposits, which are also referred to as "lime scale" or "hard water scale." Calcium and other minerals in your water leave behind this residue. Remove calcium deposits from your hot tub with inexpensive household items.
