SpaPure Defoamer | Instant Hot Tub Foam Remover

• 1 x SpaPure Defoamer (1 pint / 16 fl oz, liquid)

• Eliminates foam on contact — clears surface foam within seconds of application
• Concentrated, long-lasting formula — a small dose (one capful) treats a typical spa
• Won't clog filters — contains no oils, so it won't foul your cartridge or equipment
• Targets the real culprits — soaps, cosmetics, lotions, and other bather-introduced residues
• Soak immediately — the spa may be used right after treatment
• Works with every system — compatible with chlorine, bromine, biguanide, and mineral sanitizers

Foam forms when surfactants — the foaming agents in soaps, detergents, and cosmetics — collect in the water and trap air as the jets churn it. SpaPure Defoamer works by breaking the surface tension of those bubbles, collapsing the foam back into the water almost instantly.

It's important to understand what that does and doesn't do: the defoamer removes the foam, not the contaminants causing it. The soaps and oils are still in the water — which is why foam often returns and why the lasting fix is balancing the water or refreshing it. Think of this as the fast, on-demand tool that makes the spa usable immediately while you address the source.

Pro Tip: Less is more with defoamer. Start with a single capful (1/2 oz) right where the foam is heaviest — overdosing doesn't kill foam faster and just loads more product into the water. If one capful doesn't fully clear it, wait a moment and repeat rather than pouring in a big dose up front.

Never mix different products together in the same bottle or pail. Add this product directly to the spa water.

1. Shake thoroughly before use.
2. With the contents shaken, pour 1/2 ounce (1 capful) directly into the water where the most foam is present. The foam clears within seconds.
3. Repeat the treatment if necessary until the foam is gone.
4. The spa may be used immediately after treatment.

If your spa continuously experiences foaming, the water may be out of balance or may need to be drained and refilled with fresh water. If issues continue, contact your local dealer for advice.

Pro Tip: Keep the bottle within arm's reach of the spa. Foam tends to show up right when you're about to get in and have guests waiting — a capful poured at the surface clears it in seconds, so a defoamer on the shelf next to the tub is one of those small conveniences you'll be glad you have.

SpaPure Defoamer is compatible with chlorine, bromine, biguanide, and mineral sanitizing systems, so it fits any spa regardless of how you sanitize. Because it contains no oils and won't clog filters, it's safe to use alongside the rest of your routine.

As an "accessory" product, it can generally be added to the water without waiting on your other chemicals — but as always, never mix it with other products in the same bottle or pail; add it directly to the spa. It pairs naturally with a calcium hardness increaser (since low hardness is a frequent foam cause) and with SpaPure test strips for confirming the balance that keeps foam from returning.
