Having a hot tub or spa tub is perfect for relaxing or entertaining friends. However, these tubs can be a breeding ground for bacteria, and over-chlorinating will not eliminate it. Most people are guilty of not cleaning out their hot tubs often enough. If you do not thoroughly clean them, the hot tubs will not only collect bacteria, but stains will form around the edges of the tub shell. Keeping a hot tub or spa cleaned well is the best way to prevent bacteria and stains from forming in the tub and prevent infections in those using the tub.


Step 1

Skim the water with the leaf skimmer. This will remove leaves, dirt and grass that are on the surface of the water.

Step 2

Vacuum the hot tub with a water vacuum. The vacuum will suck up any leaves, bugs, dirt or debris that have fallen into the water or are on the bottom of the tub.

Step 3

Drain the hot tub of all water, and take the filter bucket out. Rinse out the filter with water to wash away dirt, leaves or bugs.

Step 4

Mix 1 cup of bleach and 1 cup of water together in a large bucket. Dip a sponge into the bucket, and wipe down the interior of the tub. Use this mixture on the filter and the filter bucket. The bleach will kill any bacteria in the tub and get rid of any stains.


Step 5

Apply the bio-cleaner to the hot tub with a sponge. Clean the tub with this solution, which will also remove dirt and stains. For tough stains, apply the bio-cleaner to a hard-bristled toothbrush, and scrub the stain for 3 minutes.

Step 6

Refill the hot tub back with water.


Cleaning your hot tub with a leaf skimmer and a water vacuum daily are the best ways to keep your hot tub clean in between scrubbing it.
