To most people, soaking up in an inflatable hot tub is the highlight of their day because they can relax after a long day of work. However, one of the most common problems that people encounter when they take a dip in their hot tub would be the spa foaming problems. This happens when unhealthy foam builds up on the surface of the water and makes it thick and dirty. Thus, it’s very important to use the best hot tub defoamer to make your hot tub 100% foam-free and germ-free.
What Is a Hot Tub Defoamer
Most people would ask themselves why do some hot tubs get foamy? The answer lies in the chemicals and dirt that stick to the water after it is used. If you want to know how to get rid of hot tub foam, as well as how to prevent hot tub foam effectively, then this article is for you.
A hot tub defoamer is an anti foaming chemical that prevents the formation of foam in water. There are various kinds of defoamers such as oil types, silicones, alcohols, and glycols. We will further discuss some of the common types later in the succeeding sections. What it does is that it reduces the tension in the water that the foam creates. This, in turn, would dissipate the foam and make the water clearer and thinner.
What Are The Advantages of Using a Hot Tub Defoamer
- It makes the water clearer. Since foam is one of the main reasons as to why the water is turning murky, then using the best hot tub defoamer can actually clear the water by dissolving the foam.
- It eliminates the foam build-up in the water. Aside from dissipating foam, it can also prevent foam from building up by staying in the water for a while and balancing out the chemicals in the water.
- It makes the water less thick and gooey, which is caused by the foam. The foam in the water makes the water thick and dirty looking, so if you use the defoamer to take out the foam, the water will be less thick.
- To a certain extent, it cleans the pool from the chemicals that create the foam. The foam buildup is usually due to the chemical buildup that is, in fact, quite harmful to your body. By cleaning up the foam, you are actually getting rid of the chemicals as well.
- It dissipates the dirt and the other unwanted materials that build up foam in the water. Aside from the chemicals, it also cleans away dirt and other unwanted components that contribute to the foam build-up.
Types of Defoamers
The following the different types of hot tub defoamers:
- Oil Based Defoamers
The oil based defoamers make use of oil such as vegetable oil or mineral oil in order to dissolve the foam. It is insoluble in foam and can clear the foam from the water. Because it contains a bit of wax, the performance is more effective. This type of defoamer may even prevent further spread of the foam. This is the type that is often used in pools.
- Water Based Defoamers
Unlike the oil based defoamers, the water based ones use water to carry the oils and waxes found in the defoamer. There are also oils like vegetable oils in water based defoamers, but the oils are not the carriers, unlike the oil based ones.
- Powder Defoamers
Powder defoamers are a bit similar in principle to the oil based defoamers with regard to the content. The only difference would be that powder defoamers are in powdered form. They would often be added into detergents and other liquid cleaners, which can then be added in the water to dissipate the foam.
- Silicone Defoamer
The silicone based defoamers are made of hydrophobic silica, which dissolves into silicone oil. Because of its content, it is known as an emulsifier that is added to the water so that it can spread the silicone and dissipate the foam very easily. The defoamer may also include other silicone liquids like silicone glycol and others.
