Leisure Time Jet Clean | Plumbing Purge Cleaner

• (1) Leisure Time Jet Clean — 16 fl. oz. (1 pint) concentrated low-foaming plumbing purge cleaner
• Child-resistant cap with measured-pour opening
• Full step-by-step procedure printed on the bottle label

• Cleans inside spa plumbing — the part of the spa nothing else in your routine ever reaches
• Dissolves organic buildup, biofilm, body oils, and lotion residue from internal pipes and jet bodies
• Removes mineral scale from plumbing surfaces that contributes to flow restriction
• Restores jet pressure — clogged plumbing reduces flow far more than dirty filters do
• Prevents black flake and grey debris from sloughing off pipe walls into the water
• Low-foaming formula — designed for in-system purge use without overwhelming the spa with foam
• One-bottle, one-treatment — 16 oz is a complete purge for a standard residential spa
• Works in jetted bathtubs too — use a half bottle (8 oz) for indoor jetted tubs
• Universal sanitizer compatibility — works with chlorine, bromine, ozone, mineral cartridge, and biguanide systems
• Made in the USA by Leisure Time, a trusted name in spa chemistry for over 40 years

Every soak introduces organic load into the water — body oils, sunscreen, lotion residue, sweat, hair products. Sanitizer handles the bacteria, the filter catches some of the particulates, but the dissolved oils and organic compounds get circulated through the plumbing system every time the jets run. Over weeks and months, those oils coat the inside of the pipes with a thin layer of organic film. That film attracts and holds more contamination, builds up in thickness, and eventually develops into a stable biofilm: a community of bacteria living inside a protective layer of organic gunk attached to pipe walls.

Biofilm is the hidden enemy in spa water care. It's protected from sanitizer by its own physical structure, so chlorine or bromine in the water can't penetrate it. It releases small amounts of bacteria back into the water continuously. And it grows in the dark, unreachable interior of pipes you'll never see from outside. The most reliable diagnostic sign that biofilm has reached problematic levels is when jets are turned on after a period of low use and visible black or grey flakes appear in the water — that's biofilm physically detaching from pipe walls.

Jet Clean uses a combination of surfactants (which emulsify oils and break up biofilm structure) and mild chelating agents (which dissolve mineral scale). The product circulates through the entire plumbing system at full water volume, penetrates and breaks down the buildup that's coating pipe interiors, and then drains out with the old water — taking the contaminants with it. The 1-hour static soak between jet cycles is critical: that's when the cleaning chemistry actually works its way into pipe deposits that flowing water alone wouldn't dislodge.

Pro Tip: Owners who use the chlorine-free Reserve & Renew bromine system need to purge more often, not less. Bromine systems don't oxidize organic load as aggressively as chlorine programs do, so the dissolved oil and lotion residue that gets through the filter has more chance to build up in plumbing over time. Schedule Jet Clean every drain cycle (so every 3 months) rather than every other drain. Skipping the purge on a bromine spa is the most common reason owners eventually report "the water just doesn't feel as clean as it used to."

Standard Plumbing Purge (Every 3–4 Months at Drain-and-Refill)

1. Remove the filter cartridge from the filter housing before adding Jet Clean. Clean the removed filter separately with Leisure Time Filter Clean while the purge runs — this gives you a fresh filter for the new fill.
2. With the spa full of warm water (do not add to cold water — heat helps the chemistry work), add the entire 16 oz. bottle of Jet Clean directly to the spa water.
3. Turn the pump ON and run the jets at full speed for 15 minutes. This circulates the cleaning solution through every pipe in the system.
4. Turn pump and jets OFF. Let the spa sit static for 1 hour. This soak time is critical — it lets the chemistry penetrate and break down deposits inside the pipes.
5. Turn the pump back ON and run jets and air blower together for another 15 minutes. This final agitation flushes loosened contaminants out into the main water volume.
6. Drain the spa completely. Hose off the inside walls while draining to remove any debris that surfaced during the purge.
7. If foaming occurs during drain (some buildup levels cause this), partially refill the spa, drain again, and repeat as needed until water runs clear.
8. Refill with fresh water and resume your normal Simple Spa Care Program: balance pH and alkalinity, add Metal Gon if needed, dose sanitizer, install the clean filter.

Jetted Bathtub (Indoor) Purge

1. Fill the tub with warm water above the highest jet.
2. Add ½ bottle (8 oz.) of Jet Clean for a standard indoor jetted bathtub.
3. Run jets for 15 minutes.
4. Drain and rinse the tub thoroughly.

Recovery Purge (Stagnant or Neglected Spa)

For spas that have sat unused for extended periods, or that show visible black/grey flakes when jets first turn on, do not get in the water. Skip directly to the purge procedure above, then drain and refill before any soaking. In severe cases, repeat the full purge with a fresh bottle of Jet Clean on the new fill before adding any other chemistry.

Storage & Handling

• Store in original container in a cool, dry, well-ventilated area
• Keep tightly closed when not in use
• Protect from freezing — liquid formula can lose effectiveness if frozen
• Keep out of reach of children and pets
• Do not mix with other chemicals in undiluted form — always add directly to spa water

Pro Tip: The most overlooked step in this whole procedure is removing the filterbeforedosing Jet Clean. Leave the filter in place during a purge and the cleaning chemistry attacks the filter media itself — the same surfactants that dissolve plumbing biofilm will also degrade pleated filter fibers if soaked in concentrated solution for an hour. Five seconds to pull the filter out saves you a $40 cartridge and a damaged-filter-in-fresh-water complaint a week later.

• Hazmat Classification: Non-hazardous for standard ground shipping

Jet Clean is formulated for use in all residential spas, hot tubs, and jetted bathtubs, regardless of sanitizer type, shell material, or brand. Because the product is flushed completely out of the system before refilling, it does not interact with the new water chemistry.

• Spa shells: acrylic, vinyl, fiberglass, rotomolded plastic, stainless steel
• Equipment: safe on heater elements, circulation pumps, jet bodies, plumbing, and internal hardware
• Filter cartridges: remove the filter before applying Jet Clean — the cleaning chemistry can damage filter media if left in place during the purge cycle. Clean the removed filter separately with Filter Clean while the purge runs.
• Use cases: hot tubs and portable spas (full bottle), indoor jetted bathtubs (half bottle), swim spas (use per the gallon-rate formula)
• Companion products: use alongside Leisure Time Filter Clean during the purge — clean the filter while Jet Clean works on the plumbing; pairs with the full Leisure Time Simple Spa Care line for fresh-fill startup after the purge
• Brand fit: works in Hot Spring, Caldera, Sundance, Jacuzzi, American Whirlpool, Bullfrog, and every other residential spa brand
