Spa Marvel Cleanser is a granular deep-cleaning product that purges the hidden gunk out of your spa's pipes, plumbing, and equipment — the buildup your sanitizer and filter never r each. You run it in the existing water before you drain and refill, and it pulls organic, mineral, and chemical residue out of the lines so you can start your fresh fill on a genuinely clean system. This is the step most owners skip, and it's the reason a lot of "fresh" water never feels fresh. Over time, biofilm and oils coat the inside of a spa's plumbing where no sanitizer can scrub them. When you drain and refill without flushing, that film immediately starts contaminating your brand-new water — which is why scum lines, odors, and cloudy water can show up days after a refill. Spa Marvel Cleanser strips that layer out first. It's also the right first move on a brand-new spa. Factory plumbing carries leftover residue from manufacturing — wax, lubricants, silicone, sawdust, oils, and resins — and a Cleanser purge clears it before your first soak. Whether you're opening a new tub or doing a routine water change, Cleanser is the prep step that sets up everything else, especially a fresh dose of Spa Marvel Water Treatment & Conditioner. Pro Tip: Run Cleanser in the old water, right before you drain — not after you refill. The whole point is to lift contaminants out of the plumbing so they leave with the dirty water. Cleansing a fresh fill defeats the purpose and means you'd have to drain again. Brand Spa Marvel® Show more
