Natural Chemistry Spa Pipe Cleanse - 1 L / 32 oz Bottle

Pipe Cleanse attacks the root cause of most spa maintenance problems- the buildup of non-living organic waste contamination. Oils, lotions, cosmetics, hair products, and other non-living organics build up in spa water to produce cloudiness, unpleasant odors, and foaming. These contaminants collect and build up in spas, circulation systems and filters. By purging the spa plumbing, you can improve water clarity and reduce the amount of time and effort needed to maintain your spa.

Features and Benefits:

  • Helps clean non-living organic waste from inside spa plumbing using a concentrated formula with smartzyme technology
  • Attacks the root cause of maintenance problems caused by non-living organic contamination

INSTRUCTIONS

Directions for use:

Spas/Hot Tubs:

1. Remove cartridge filter elements.

2. With spa water temperature at 95ºF or higher and circulation running, add entire contents of bottle to spa water.

3. Run jets for a minimum of 5 minutes.

  • Note: If foaming becomes excessive, turn jets off. Some foaming is expected during the cleanse process.

4. Maintain water temperature at 95ºF and allow spa to circulate overnight with jets off.

5. Drain and rinse/clean out the surfaces of the spa. Refill the spa water and reinstall the filter elements.

6. Proceed with normal spa maintenance.

For Jetted Tubs:

  1. Fill tub with hot water 1" above the jets.
  2. Add 1/2 bottle of Pipe Cleanse.
  3. Turn jets on for 5 minutes (some foaming will occur).
  4. Turn jets off and let sit for at least 5 hours.
  5. Turn jets on to flush the system.
  6. Drain tub & clean surface as needed.

Natural Chemistry Pool and Spa Water Care

About Natural Chemistry Pool and Spa Water Care

Founded in 1989, Natural Chemistry shifted the paradigm of pool care by asking a simple question: "Is there a better, more natural way?" While the rest of the industry relied heavily on harsh industrial chemicals, Natural Chemistry pioneered the use of powerful, naturally based enzymes—similar to those found in your own body—to break down organic waste.

What started as a single enzyme formula to combat scum lines has grown into North America’s leading authority on specialty pool water care. Their philosophy is built on "biomimicry"—using technologies inspired by nature to solve common pool problems like algae fuel (phosphates) and greasy buildup. By breaking down contaminants rather than just masking them, their products often reduce the need for excessive sanitizers and scrubbing. For the DIY homeowner, Natural Chemistry represents the "work smarter, not harder" approach to maintenance, delivering high-end results with eco-conscious science.

Why We Trust Natural Chemistry Pool and Spa Water Care
Pioneering Enzyme Technology: They were the first to successfully stabilize natural enzymes for pool use, allowing water to "digest" oils, lotions, and pollen naturally.

Problem-Solving Focus: Rather than generic fixes, they manufacture targeted solutions for specific headaches, such as high phosphates (Phosfree) or persistent scum lines.

Efficiency & Simplicity: Their core promise is to reduce maintenance time and effort, polishing water so it sparkles without constant manual labor.

Eco-Conscious Chemistry: By removing organic load efficiently, their products often help sanitizers work more effectively, potentially lowering the total chemical burden in the pool.

Buyer's Guide: Maintenance vs. Deep Cleaning

Choose the right strength based on your current maintenance cycle.

Tier 1: Weekly Maintenance

  • Best For: Preventing scum lines and reducing filter clogging during normal use.
  • Look For: [Enzymatic Spa Cleanse] or "Weekly" labels.
  • Expectations: Breaking down oils (lotions/sweat) continuously so they don't stick to pipes.

Tier 2: The Quarterly "Purge" (Deep Clean)

  • Best For: Use only right before draining the spa (every 3-4 months).
  • Look For: [System Flush], [Pipe Cleanse], or [Spa Purge].
  • Expectations: Aggressive cleaning. Will create foam and release dark debris. Restores jet flow and heater efficiency.

The "Hidden" Clean Your Hot Tub Needs

You change your water, balance your chemicals, and rinse your filters—but is your hot tub actually clean? The reality is that 99% of bacteria in a hot tub lives in the plumbing, not the water. Over time, body oils, lotions, dead skin, and cosmetics accumulate inside the pipes where you can't see them. This creates a sticky layer called biofilm, which protects bacteria from your sanitizer and reduces jet pressure.

System Flushes and Cleansers are the solution. These powerful enzymatic cleaners break down that hidden gunk, lifting it off the pipe walls so it can be drained away.

  • Weekly Cleansers: Break down oils as they enter the water to keep filters from clogging.
  • Quarterly Flushes: A "deep purge" used right before you drain the tub to strip the plumbing bare.

If you notice frequent cloudy water, musty odors, or high chemical demand, your plumbing is likely clogged. A simple flush restores your spa to "factory fresh" efficiency.

Common Questions +

Q: Can I soak in the hot tub while the Flush product is working?
A: No. System Flush products are highly concentrated and designed to lift grime from pipes. You should not be in the water during the treatment process.

Q: How often should I use a System Flush?
A: We recommend using a flush product every 3 to 4 months, specifically right before you plan to drain and refill your spa.

Q: Why is there so much nasty foam appearing during the flush?
A: That foam is a good sign! It is visual proof that the product is working. The foam carries the brown/green biofilm and oils out of the plumbing and to the surface.

Q: Should I leave my filters in during the flush?
A: Generally, no. Remove your cartridge filters before running the flush cycle. This prevents the heavy gunk released from the pipes from instantly clogging your filter pleats.

Q: I bought a brand new hot tub; do I need to flush it?
A: Surprisingly, yes. New hot tubs are "wet tested" at the factory and water can sit in the lines during shipping, growing biofilm before it ever reaches your backyard.
