A natural de-foamer, such as household vinegar, is a chemical-free alternative to chemical de-foamers. Pour household vinegar into your spa pool at a ratio of 1:10, vinegar-to-water, to temporarily get rid of spa pool foam.
The terms anti-foam agent and defoamer are often used interchangeably. Strictly speaking, defoamers eliminate existing foam and anti-foamers prevent the formation of further foam. Commonly used agents are insoluble oils, polydimethylsiloxanes and other silicones, certain alcohols, stearates and glycols.
Antifoam agents are additives that are used to prevent the formation of foam. They work by reducing the surface tension of the liquid, which prevents the formation of the thin films of liquid that are necessary for the foam to form.
Plain white vinegar should work as a defoamer. Pour like half a cup / 1 cup in the wet vac.
Being antimicrobial, however, doesn't mean you can't clean your memory foam from time to time. If you're looking to clean memory foam, you'll need a couple of things. The cleaning products you'll need include a sponge, some warm soapy water, a vacuum cleaner, baking soda and some white vinegar.
Conventional defoamers do not qualify so the producer must find an all-natural replacement that both knocks down the foam and also does not affect taste. Many sugarmakers use sunflower oil or other oils similar.
Silicones. Silicones are especially effective for foam control – both as antifoams that prevent foam from forming, and as defoamers that react to foam and help minimize it. Silicone foam control products are available as fluids, emulsions and compounds.

Memory foam, in particular, responds to heat and becomes more malleable when warm, which means it will be softer.
A natural defoamer is an anti-foaming agent derived from natural sources, such as vegetable oils or plant extracts, used to reduce or eliminate foam in various processes.
Acetone is a relatively non-polar solvent (as compared to water, which is highly polar), and Styrofoam is made from polystyrene and foam. Due to their similar polarities, acetone can dissolve the carbon-hydrogen bonds of Styrofoam.
Oil-based Defoamers
The most commonly used are paraffin and naphthenic oils.
Oils and vinegar can help soften hardened foam slightly, but mechanical or chemical methods, such as acetone or WD-40, are far more reliable for complete removal.
Vinegar. White vinegar is used to remove spray foam. Apply vinegar to spray foam and allow it to sit for several hours, and then remove it with a scrapper.
You can also remove spray foam from your hand or skin using Wd-40, gasoline, goof-off, and lacquer thinners. Just like using acetone, apply with a clean cloth and rub gently on your hand to remove spray foam. Then wash off with warm water and soap to avoid skin irritation.
What's a natural de-foamer for spa pools or hot tubs? A natural de-foamer, such as household vinegar, is a chemical-free alternative to chemical de-foamers. Pour household vinegar into your spa pool at a ratio of 1:10, vinegar-to-water, to temporarily get rid of spa pool foam.
Pour a very small amount of olive oil onto the foam. Let the oil spread through the foam or spread it with a spoon. The oil will break down the foam by bursting the tiny bubbles.
If your spray foam mess has dried out, you can start cleaning it up by cutting away as much of it as you can. Just use a putty knife, a saw, or another appropriate cutting tool. A hard-bristled brush will also help you remove dried spray foam, especially if you can't get at it with a cutting tool.
Silicone antifoams are incredibly effective and potent at very low concentrations. They can be easily combined with other active ingredients to enhance their defoaming properties. Non-silicone antifoams usually rely on surfactants, but can also be water-based or oil-based.
In most cases, the most efficient foam control is realized by adding a small fraction of chemical additives (typically, between 0.01 and 0.5 wt. %) whose main role is to prevent or reduce the formation of undesired foam [12–14]. These additives are usually termed “antifoams”.
The water-dilutable defoamer preparations are produced by first mixing the defoamer oil and the emulsifier with the help of a high-speed stirrer and then working in the hydrophobic silica first and subsequently mixing in the corresponding amount of hydrophilic silica under the same sitrring conditions.
The general process by which these antifoam agents are made requires that a mixture of the dimethylpolysiloxane fluid and the untreated and/or treated fumed silica filler is initially heated to about 150° C. in order to disperse the filler. The mixture is then homogenized under pressure or milled and cooled.
Choosing the proper cleaning solution is one of the best ways to prevent foaming. Look for detergents and solvents specifically designed for use in parts washers. These will typically have lower levels of foaming agents and other substances that can contribute to foam buildup.
Baking soda won't directly reduce foam. It's used to raise alkalinity, which can indirectly help if low alkalinity is causing the foam.
