Could not believe what came out
Ran it before my water change and the stuff that came out of the jet lines was eye opening. Glad it is out of there now.

Product Details
The water looks fine until you drain it, and out comes the gunk that was hiding in your plumbing. Body oils, dead skin, lotions, and biofilm build up inside jet lines and internal piping where you never see them, and they keep recontaminating fresh water after every refill.
Paddle Jet Line Cleaner flushes that buildup out before you drain. Add 2 oz per 100 gallons, run the jets on high for 20 to 30 minutes (or let it sit overnight on low for a heavier job), then drain, rinse, and refill with clean water. What comes loose is the stuff that was quietly fouling your tub from the inside.
It works in hot tubs, spas, and jetted bathtubs, so one bottle covers every jetted setup in the house. A 16 oz bottle handles up to 8 hot tub treatments. Run it with every water change, or at least every three months, and monthly for jetted bathtubs that see regular use.
A portion of every Paddle purchase funds the Doggy Paddle Initiative, supporting no-kill shelters and dog rescues nationwide.

Refill stayed clear
My fresh water always used to cloud up fast. I flushed the lines first this time and the new water held up so much better.

Used it on my jetted tub
Works in a bathroom jetted tub too. Ran it on high for about half an hour and the jets pushed out a lot of buildup. Happy with it.

Part of my routine now
Simple to dose, run the jets, then drain. I do it every water change now and the tub stays fresher between cleans.

FAQs
What does a jet line cleaner do?
It flushes the oils, lotions, and biofilm that collect inside your hot tub's internal jet lines and plumbing, the buildup that never drains out with the water.
Clearing the lines before a water change means you refill into clean plumbing instead of washing old gunk back into fresh water.
Do I need to drain my hot tub before using it?
No. Remove the filters, add the cleaner to the existing water, run the jets, and then drain, rinse, and refill afterward.
The flush happens with the tub full so the formula can move through the entire plumbing system.
How do I use it step by step?
Add 2 oz per 100 gallons, run the jets on high for 20 to 30 minutes, or overnight on low for a deeper clean. Then drain, rinse, and refill with fresh water.
Removing the filters first lets the loosened buildup flush out instead of clogging the cartridge.
How often should I flush my jet lines?
Every water change, or at least every 3 months for a hot tub. For a jetted bathtub, once a month keeps the lines clear.
Higher use and more bathers mean more buildup, so flush more often if your tub sees a lot of traffic.
Why does my fresh water turn cloudy soon after a refill?
Usually because the lines were never cleaned. You drain and refill, but the old buildup is still in the plumbing and washes back into the new water.
Flushing the lines before you drain helps your fresh fill stay clear longer.
How many treatments are in one bottle?
A 16 oz bottle handles up to 8 hot tub treatments at 100 gallons each. Jetted bathtubs use less per treatment, so you get more out of the bottle.
Dosing is based on water volume, so larger tubs use proportionally more per flush.
