Hot Tub Serum Cleaning Kit | Purge & Maintain

• 1 x Hot Tub Serum Total Cleanse (2 oz gel) — Step 1: the biofilm purge that flushes sludge from your plumbing and jets
• 1 x Hot Tub Serum Total Maintenance (16 oz) — Step 2: the weekly water care that keeps biofilm from returning
• 1 x Turbo Cleaning Mitt — for wiping down the spa shell and cover

• Complete clean in one kit — purge, deep clean, and maintain, all in one box
• Two-step Total Clean System — Total Cleanse to remove biofilm, Total Maintenance to keep it out
• Includes a Turbo Cleaning Mitt — makes scrubbing the shell and cover easy
• Do it in an afternoon — a full spa cleaning in a couple of hours, no pro needed
• Months of maintenance — the 16 oz Total Maintenance covers weekly upkeep long after the purge
• Works with every system — compatible with chlorine, bromine, salt, biguanide, and mineral

The kit follows the logic of a proper deep clean, in order. Step 1 — Total Cleanse is added to the existing water and circulated through the jets, where its foaming action breaks the biofilm loose from inside the plumbing; you'll see brown scum surface as the gunk is pulled out. As the spa drains, the Turbo Cleaning Mitt makes it easy to wipe that loosened grime off the shell before it dries. Step 2 — Total Maintenance is then added weekly to the fresh fill, keeping bacteria from re-establishing in the now-clean plumbing.

Together, the two products cover what no single product can: one removes existing buildup, the other prevents its return. Both are compatible with your sanitizer and work alongside it — Total Maintenance is a supplement to your sanitizer, not a replacement, so you always keep an EPA-approved sanitizer at proper levels.

Pro Tip: Scrub the shell while it's draining, not after. As the purged water drains out, the loosened biofilm can dry and stick to the shell — and it's much harder to remove once it does. Use the Turbo Mitt to wipe the surfaces down as the water level drops, working top to bottom, and the whole job stays quick and easy.

Balance and sanitizer note: after refilling, balance the water — total alkalinity 100–180 ppm, pH 7.4–7.6, calcium hardness 150–400 ppm — and always maintain an EPA-approved sanitizer.

Step 1 — Purge & Deep Clean (Total Cleanse)

1. With the filter(s) left in place, add 1 level teaspoon of Total Cleanse per 100 gallons of the spa's current water.
2. Open the air controls and run the jet pump(s) on high for 15–20 minutes. Foaming and brown scum are normal; watch that the foam doesn't overflow.
3. If a lot of scum is still releasing, run the jets on high for another 20 minutes.
4. Drain the spa. As it drains, use the Turbo Cleaning Mitt to wipe the loosened gunk off the shell (top down) before it dries.
5. Rinse the surfaces, clean or replace the filter cartridge(s), and reinstall them.

Step 2 — Refill & Maintain (Total Maintenance)

1. Refill with fresh water, balance the water, and re-establish your sanitizer.
2. Add 1 fl oz of Total Maintenance per 100 gallons, then repeat weekly (same day each week). A small amount of foaming is normal.
3. Test your water weekly and rinse your filter regularly.

Pro Tip: Don't forget to clean the filter between the two steps. During the purge, the filter catches everything the Total Cleanse breaks loose, so it comes out loaded with gunk. Cleaning it thoroughly (or dropping in a fresh cartridge) before you refill means you're not putting all that captured biofilm right back into your clean water and starting the maintenance phase behind.

The Hot Tub Serum Cleaning Kit works with any spa on any sanitizer system — chlorine, bromine, salt/SWG, biguanide, and mineral systems (including The Frog®, @ease®, and Nature2®). The purge and maintenance products both layer onto your existing routine without changing how you sanitize.

This kit is the starter version of the Total Clean System: once you've used the Total Cleanse and worked through the 16 oz Total Maintenance, simply reorder the individual products — Total Cleanse every 4–6 months for purging, and Total Maintenance (available in larger sizes) for ongoing weekly upkeep. For swim spas, use Swim Spa Serum for the weekly step instead.
