Bubbles are entirely natural, but foaming is not. Although a bubble bath in a conventional tub is enjoyable, the accumulation of foam is an issue in a hot tub. 

Several firms have professional de-foaming chemicals that may be mixed with the water. However, if you choose a more organic and cost-effective approach, there are a few domestic things that you can use to keep foam away from your precious hot tub.

Sit back and read through to understand how to get rid of foam in hot tubs naturally.

How is Foaming Caused in a Hot Tub?

In theory, a few distinct factors may cause the hot tub to foam. However, they are all connected to modifying the chemical concentration in the water.

Any compounds you may be using, such as perfume, cosmetics, cologne, shampoo, and soap residue, affect the water’s chemical levels in the hot tub. 

Children frequently prefer to bring their food and beverages with them. However, the presence of oils and carbohydrates in food might also cause the hot tub to froth up.

Every human being perspires and has dead tissue sheds hair. All of this will affect the pH levels in the hot tub, which will ultimately lead to further troubles.

How to Determine the Cause of Foaming in Hot Tubs?

Finding an acute treatment might be difficult with several potential reasons for foaming in hot tub water. You can commence a practical solution by determining the source of the foam. 

You can begin by having your water tested by an expert.

Suppose the chemical levels in your water are out of equilibrium. In that case, there is a significant likelihood that your problem is caused partly by the water’s poor chemical balance.

If your water balance is OK, but your sterilizer levels have dropped, the problem might be related to bacterial formation. 

Add extra disinfectant and retest your water the following day (you can purchase a home testing kit to determine the chemical levels during the next test). If the sanitizing level drops again, the hot tub most likely has a microbial accumulation.

Suppose your water level is neutral and has a decent sanitizer residue. If you see an oily “circle” on the casing of the hot tub surrounding the surface of the water, this might be due to an accumulation of oils and creams.

In that case, the problem might be an oil or lotion accumulation.

If you still can’t discover an obvious explanation, surfactant accumulation is the most probable explanation for your problem.

Ways To Naturally Fix Foaming in Hot Tubs

Fixing the foam in your hot tub naturally should be much easier if you determine the cause of the problem.

Firstly, adjust your freshwater to treat frothy water appropriately (if needed). If changing the water does not resolve the issue, you will have to remove the accumulation of waxes, creams, and cleansers causing these problems. 

Start by adding an oil-absorbing pad to the water to do this. This absorbent will slowly soak in any oils, cleansers, or cosmetics on the surface of the liquid. You should observe the foam diminish and then cease after a few days. 

Suppose the foam does not disappear after a week. In that case, you can add a second sponge to accelerate the process or just empty and refill the hot tub.

Suppose you feel that your frothy water problem is caused by biofilm. In that case, the only solution is to empty and clean the hot tub’s pipelines to eliminate the bacteria accumulation.

Although “anti-foam” compounds may be added to water, they are only intended to gradually dissolve the link between the water and the surfactants. 

If the water is not subsequently treated, the foam will reappear once the anti-foam compound has been depleted (typically within 24 to 48 hours).

Other Natural Home Remedies to Eradicate Foam From Hot Tubs

Vinegar is an excellent de-foaming solution. You must make this solution at a 10 to 1 ratio. If there is only a tiny foam coating in your hot tub, you may pour vinegar into the liquid. 

Put 1 gallon of vinegar for every 100 gallons of water in the hot tub. The negative is that the liquid may have a slight vinegar odor, but this will dissipate with time.

Combine baking soda, two parts vinegar, and seven parts water to make a vinegar and baking soda mixture in a container. Although this mixture may produce an initial froth, the vinegar will activate the baking soda. 

Fill the hot tub with the solution and leave it to operate for at least half an hour.

The vinegar solution will destroy the skin cells and oils responsible for the foam.

If you’ve applied these remedies, but the hot tub is still foamy, the best option is to drain it, carefully clean it, then refill it with new water.

At this point, you can apply the chlorine shock method to limit the possibility of foaming. 

Suppose the chlorine shock fails to aid you. In that case, home remedies will not be powerful enough to remove the foam. 

You will need to apply a de-foaming chemical to remedy the problem.

Conclusion and Prevention of Foam Accumulation

The most straightforward technique to keep your hot tub from foaming is to decrease the number of lubricants, moisturizers, and cleansers you use in it. 

The most straightforward approach is to take a quick shower before entering the hot tub to eliminate the majority of the beauty products you may have on your skin.

You may also significantly minimize the quantity of washing soap and fabric softener released into the water by cleaning your bathing suits separately with a lesser amount of cleansing solution.

Think about utilizing a protease cleaner like Spa Perfect or Spa Synergi Cleanse if you do everything mentioned above.

However, no matter how tough, surfactants will gradually accumulate in the water. If the liquid in your hot tub is becoming old and bubbly, adding a tiny amount of anti-foaming agents to the liquid weekly can help eradicate the foam.
