Description

Hot Tub Serum Triple Action Spray CleanerĀ is aĀ spray-top surface cleanerĀ that tackles the grimy, musty problems that developĀ above the waterline — on the spa shell, the underside of your cover, and around the headrests and pillows. It's the simple, on-the-shelf answer to two of the most common spa complaints: thatĀ musty smell when you open the cover, and the mold and mildew that creep across covers and pillows.

Here's why those areas cause trouble: the surfaces just above the water and beneath the cover stayĀ warm, damp, and darkĀ while the spa sits unused — a perfect breeding ground for the bacteria, mold, and mildew that create odors and staining. Your sanitizer protects the water, but it never reaches these surfaces. Triple Action Spray does, cleaning theĀ "tidal zone"Ā and cover so contaminants can't take hold.

Best of all, it worksĀ without draining the spa. A few seconds with a spray bottle after each soak keeps your hot tub looking clean, smelling fresh, and inviting — no cleanout required. Made in the USA.

Pro Tip:Ā Make it the last thing you do every time you get out. A quick spray of the tidal zone as you step out of the spa — before you close the cover — is what stops odors and mildew before they start. It takes ten seconds and means you're greeted by fresh, clean water instead of a musty smell next time you lift the cover.

  • Made in the USA — from Serum Watercare
How It Works

Spa odors are usually generated byĀ bacteria growing above the waterlineĀ while the spa sits unused under its cover. The band of shell just above the water — the "tidal zone" — along with the cover underside and headrests, stays humid and warm, giving mold, mildew, and odor-causing bacteria an ideal place to grow that your in-water sanitizer never touches.

Triple Action SprayĀ cleans and treats those exact surfaces, removing the organic film that feeds growth and preventing mold and mildew from taking hold. Because it targets the source of the odor and staining directly, a quick regular spray keeps the whole spa environment fresh — not just the water.

Pro Tip: Don't forget the top of the cover, too. Spray owners find it works just as well on the outside of the cover as the inside — so if your cover collects mildew or grime on top from the elements, give it a spray and wipe as well. One bottle handles the whole cover, inside and out.

Directions for Use

Use Triple Action Spray frequently while the spa is in use to treat the tidal zone, cover, and headrests — no need to drain the spa.

After Each Use

  1. Upon exiting the hot tub, spray Triple Action on theĀ "tidal zone"Ā of your spa shell — the 4–6 inches of shell just above the water line.

Weekly

  1. Spray theĀ underside of your spa coverĀ andĀ around the headrests and pillows.
  2. Wipe away any residueĀ that forms before closing your cover.

Pro Tip: If you already have mildew or odor built up, spray a little more generously and let it dwell a minute before wiping the first few times. Once you've knocked the existing growth back, the light after-each-use routine is all it takes to keep it away — prevention is far easier than catching up.

Compatibility

Triple Action Spray Cleaner is aĀ surface product, so it works withĀ any spa on any sanitizer system — chlorine, bromine, salt, biguanide, or mineral. Because you're treating the shell, cover, and headrests rather than the water, it fits every routine without affecting your water chemistry.

It complements the rest of the Hot Tub Serum line: whereĀ Total MaintenanceĀ keeps the plumbing clean andĀ Total CleanseĀ purges it, Triple Action Spray handles theĀ surfaces above the waterlineĀ that neither of those reaches. Together they keep the entire spa — water, plumbing, and surfaces — clean and fresh.

Hot Tub SerumĀ® Brand FAQs

What is Hot Tub Serum, and how is it different from other spa chemicals?

Hot Tub Serum is an EPA-registered water care line built around one idea most spa chemicals ignore: cleaning and protecting the inside of your spa's plumbing. Its products prevent and remove biofilm— the bacterial sludge that builds up in pipes and jets and keeps re-contaminating your water. Made by Serum Watercare, the line is registered with the EPA in all 50 states.

Does Hot Tub Serum replace my sanitizer?

No. Hot Tub Serum works along side your sanitizer, not instead of it. You still need to maintain an EPA-approved sanitizer (chlorine, bromine, salt, or a mineral system) at proper levels. Serum keeps your plumbing clean and makes your sanitizer more effective — so most owners end up using less of their other chemicals — but a sanitizer is always required.

What is biofilm, and why does it matter in a hot tub?

Biofilm is a slimy layer of bacteria that forms inside spa plumbing where you can't see or reach it. It protects the bacteria within it from your sanitizer, which is why an untreated spa can stay cloudy, smelly, or sanitizer-hungry no matter how carefully you dose. Because it hides in the pipes, it keeps coming back until it's addressed at the source — which is exactly what Hot Tub Serum targets.

How does the Hot Tub Serum Total Clean System work?

It's a simple two-step regimen. First,Total Cleanse is added before a drain-and-refill to purge existing biofilm and gunk out of the plumbing. Then, once the spa is refilled,Total Maintenance is added weekly to keep that biofilm from ever coming back. Purge to clean, maintain to keep it clean.

Is Hot Tub Serum compatible with my sanitizer system?

Yes. Hot Tub Serum is compatible with all sanitizing systems — chlorine, bromine, salt water generators, biguanide, and mineral systems such as The FrogĀ®, @easeĀ®, and Nature2Ā®. It's also unaffected by pH swings, cyanuric acid, and common oxidizers, so it keeps working even when your water chemistry drifts.

Is there a warranty benefit to using Hot Tub Serum?

Serum Watercare offers a Lifetime Jet Warranty for owners who use Total Maintenance weekly through an authorized dealer's auto-ship program. Because jet failure is often caused by scale and water-chemistry buildup that Serum helps prevent, the program covers replacement of removable jet inserts that fail due to water chemistry.

About Hot Tub SerumĀ®

Hot Tub Serum is a water care brand fromĀ Serum Watercare, built on a simple insight the rest of the industry overlooked: the biggest threat to clean hot tub water isn't in the water you can see — it's theĀ biofilm hidden inside your plumbing. Where conventional chemicals only treat the water in the shell, Serum's EPA-registered formulas clean and protect the pipes, jets, and internal surfaces where bacterial sludge takes hold.

The result is theĀ Total Clean System: a purge product (Total Cleanse) that scrubs existing biofilm out of the plumbing before a drain-and-refill, and a weekly maintenance product (Total Maintenance) that keeps it from ever returning. Registered with the EPA inĀ all 50 statesĀ and backed by a first-of-its-kindĀ Lifetime Jet WarrantyĀ for regular users, Hot Tub Serum is designed to make spa care simpler while protecting the equipment you've invested in — for water that stays clear, soft, and fresh with less work.
