Bacteria and other impurities may make their way into your spa water daily. It is essential to maintain enough circulation to prevent these pollutants from becoming an issue in the first place.

During circulation, the water flows through the filter, trapped by the suspended particles in the water.

It comprehensively distributes sanitizing chemicals, killing germs, eliminating unwanted substances, and assisting in preventing issues.

In most cases, people think flushing their hot tub scum balls with warm water in the sink will be sufficient.

However, this is not always the case, and you will need to ramp up the amount of cleaning. Let us have a look.

Four ways of cleaning Hot Tub Scum Balls

A wide range of reusable hot tub scum balls is available in the market.

You must, however, ensure that all of the muck and slime has been removed from the product before re-introducing it to the water source.

It’s possible to clear the scum ball by thoroughly washing it with water if there isn’t a lot of muck on the surface.

However, if this is not the case, one of the below procedures should be used.

Soap and Water

A solution that has been proposed is to clean the hot tub scum balls using soap and water.

When scumballs are collected from hot tubs that have been used often, they may need to be cleaned two or three times to remove all of the oils absorbed by the ball.

Washing Machine

Scumballs with gunk on them may generally be washed on the washing machine’s delicate cycle. Place them in a delicate bag and wash them in the washing machine.

When they come out of the washer, they will be clean, but they will most likely be twisted. However, after a few hours of soaking in your hot tub, they will return to their previous shape and size.

Vinegar Cleaning

Some people choose to clear the filth generated by the scum ball with vinegar rather than water.

Although the acidic characteristics of vinegar make it a good cleaning agent, they may also cause the hot tub scum balls to degrade over time if not used properly.



Occasionally, it’s simply better to chuck your trash after a few months and start over with fresh ones. They’re not prohibitively costly compared to hot tub chemicals, and with a wholly new scumball, you won’t have to worry about cleaning or the possibility of hot tub foam building up in your tub.
