Buying a defoamer is no easy task, especially if you've just bought a hot tub. There are a lot of different foaming agents out there too, and knowing more about the problem you’re facing can help you solve it. And that is exactly why we have compiled this buyer’s guide for you. It should provide you with some useful information about these products and help you find a defoamer that can work for you and your specific setup.
Benefits of Using Defoamers
Removing harmful chemicals
First, it’s important to know what causes foam in hot tubs. The oils, soaps, and other cosmetic products that can mix in with your water whenever you take a soak are the main reason. Chemicals from these products and substances do not only cause foam, but they can also be pretty risky for anyone coming in contact with them, too.
Defoamers can help remove this foam from the water, and they can also help with getting rid of the chemicals that cause the buildup in the first place.
Eliminating dirt from water
The water in pools and hot tubs are prone to gathering a lot of impurities. And these don’t just include the chemicals from other products that mix in with the water. The water in pools or hot tubs can also contain more dirt than you might realize, and another benefit of using defoamers is that they can also help remove this dirt along with foam.
Types of Defoamers
Silicone-based defoamers contain hydrophobic silica, which is diffused in silicon oil. Emulsifiers are also added to make sure the silicone spreads evenly in a product. Silicone-based defoamers can also work effectively without altering water chemistry.
Just like their name sounds, water-based defoamers are made up of a water base. Different types of oils, like mineral oil and waxes, are then added to the water to create a product that acts as a defoamer. What makes water-based defoamers a good option is that they are unlikely to leave behind an oily residue.
Oil-based defoamers can be made of different types of oil, including vegetable oil and mineral oil. These products can also contain other materials, such as waxes or hydrophobic silica, to make a product more effective. Oil-based defoamers might be more effective at removing foam compared to other types of defoamers, too.
Powder defoamers aren’t really that different from oil-based defoamers, except that they come in powder form. These defoamers are made from a mixture of different types of oils and waxes that work together to help remove the foam.
Things To Consider When Buying Defoamers
Pools and spa water almost always contain chemical compounds, like chlorine or bromine, to help kill bacteria. So, if you use a defoamer that does not work well with these chemicals, it can throw off the balance of the chemical levels of your water.
This is why you should make sure a product won’t alter your water’s chemistry before you buy it, and you also check if it is compatible with the chemicals added to your pool or hot tub, too. And speaking of chemicals, you should also ensure that the defoamer you purchase does not include chemicals that can cause irritation or harm to your eyes or skin.
Not everyone leads the same kind of lifestyle. For example, if you're all about green solutions and products, make sure you buy a defoamer that is environmentally friendly. These kinds of products often contain solutions that are biodegradable and shouldn’t harm marine life when they’re flushed out.
Before buying a defoamer, you should also make sure that a product does not contain any ingredients you are allergic to. Even after flushing, some trace amounts of a defoamer can still linger in a hot tub and your skin might get exposed to it. So, for example, if you’re allergic to silicone, you should steer clear of silicone-based defoamers.
Because defoamers are made of chemicals, they are pretty likely to have a few side effects. These can include your water having an oily residue after using a product — or there can even be some irritation. Make sure you look at the reviews for whichever defoamer you choose, and you should also remember to carefully consider the ingredients so you don’t end up purchasing a defoamer you might be allergic to.
How We Picked Our Favorite Defoamers
The products above only contain defoamers that fall within a reasonable price range. The prices of these products fall between $15 and $30 if you buy the standard size. And at the same time, these products are highly rated in their category and should also be pretty effective, too.
Any defoamer you pick out should be safe to use, and they shouldn’t come with serious side effects such as skin or eye irritation either. This should be true of the products above too, and it’s also important that the product you choose is effective without interfering with the chemistry or pH levels of the water in your pool or hot tub.

People Also Asked
Q: What causes excessive foam in my hot tub?
A: When you take a dip in your hot tub, your body is likely covered in lotions, oils, or makeup. Even the laundry detergent used to wash your swimsuit can be a culprit, too. When all these products mix with water, it can lead to foam buildup. And foam can also result from a chemical imbalance in your pool or the shedding of dead skin cells from your body.
Q: What is the difference between a defoamer and antifoam?
A: A defoamer and an anti-foam agent may not necessarily be the same thing. An anti-foaming agent can help prevent the build-up of foam in the first place. Defoamers, on the other hand, can only help reduce pre-existing foam. So, when you use a defoamer, it can only remove the existing foam and cannot stop more foam from building up later.
Q: What makes a good defoamer?
A: A good defoamer isn’t just a product that produces results. Good defoamers should also not contain chemicals that can irritate the eyes or the skin. And quality products should also work without interfering with water chemistry or leaving behind oily or slimy residue.
