Spa Marvel Cleanser | Deep Spa Plumbing Purge

• 1 × Spa Marvel Cleanser — 8 oz bottle of granular deep-cleaning formula
• Use directions — printed on the bottle label

• Deep-cleans plumbing and equipment — reaches the internal pipes and jets that normal sanitizing and filtration can't
• Removes organic, mineral, and chemical residue — biofilm, oils, scale, and accumulated chemical buildup in one purge
• Clears manufacturing residue from new spas — strips wax, lubricants, silicone, sawdust, oils, and resins left from the build process
• Protects your fresh fill — starting clean keeps scum lines, odors, and cloudy water from returning days after a refill
• Sets up the Spa Marvel system — the recommended prep step before a fresh dose of Spa Marvel Water Treatment & Conditioner
• Simple granular formula — one 8 oz bottle treats a full purge cycle
• Use it routinely — designed for every drain-and-refill, not just initial setup

Spa Marvel Cleanser works by circulating through your spa's entire plumbing system in the existing water, breaking the bond between built-up contaminants and the surfaces they cling to. Biofilm — the slick, bacteria-harboring layer that forms inside wet pipes — is the main target, along with mineral scale and the oily chemical residue that accumulates over a fill cycle. Once the Cleanser loosens that material, it suspends it in the water so it drains away when you empty the tub.

Here's the sequence of a purge cycle:

1. Filters are removed so the released contaminants don't immediately load the cartridge
2. Cleanser is added to the existing water and circulated on high to drive it through every line, jet, and piece of equipment
3. Contaminants break loose from the plumbing walls and suspend in the water — you may see foam, film, or debris surface, which is the product working
4. An extended low-speed circulation keeps everything moving so the purge reaches the whole system
5. The tub is drained and flushed, carrying the loosened material out with the old water
6. A thorough rinse clears any remaining residue before the fresh fill

The result is a clean internal system — the foundation that lets a fresh fill stay clear and lets your water treatment and sanitizer do their jobs without fighting leftover gunk.

Pro Tip: Don't be alarmed if the water gets foamy, filmy, or visibly dirty during the cycle — that's exactly what you want to see. It means the Cleanser is pulling buildup out of the plumbing and into the water, where it can be drained away instead of sitting in your lines.

When to Use Cleanser

• Before every drain and refill — the routine purge that keeps your plumbing clean
• On a brand-new spa — before first use, to clear manufacturing residue
• Before starting the Spa Marvel system — especially on a previously used spa, to give the enzymes a clean foundation

Purge Procedure

1. Remove the filters from the spa.
2. Pour one bottle of Spa Marvel Cleanser into the existing water.
3. Circulate with jets on high for at least 1 hour to drive the Cleanser through the full system.
4. Continue circulating at low speed for an additional 23 hours.
5. Drain and flush the tub, then rinse thoroughly to clear any remaining residue.
6. Refill with fresh water and proceed with your water care program.
7. Repeat before every drain and refill.

Storage and Safety

• Keep the bottle tightly closed between uses
• Store in a cool, dry place, away from direct sunlight
• Keep away from children and pets
• Do not soak in the spa while the Cleanser is circulating — this is a purge cycle, not treated bathing water

Pro Tip: Clean or replace your filter cartridge right after the purge. The buildup the Cleanser pulls loose ends up suspended in the water, and a lot of it will land in the cartridge — running the purge with dirty filters back in place just recirculates the gunk you're trying to remove.

Works Alongside

• Spa Marvel Water Treatment & Conditioner — Cleanser is the prep step; purge the old water with Cleanser, drain and refill, then add a fresh bottle of Water Treatment & Conditioner to start the cycle clean
• Spa Marvel Filter Cleaner — clean or replace your cartridge after a purge, since the loosened buildup can clog a filter
• Any sanitizer program — chlorine, bromine, salt, ozone, UV, and more; Cleanser doesn't affect them because it's drained out before the refill
