Fultons

So, 15 purges followed by 15 total scrubs?! Ugh! Thankfully, it seems 5 was our magic number. Still seeing some scum at the waterline, but a Mr. Clean Magic Eraser wipes it away. I stand by my belief that a smooth shell would have been easier to clean than this textured one. Many thanks to you both for your time and expertise! What are the odds of a recurrence, and is there anything we can do to prevent it?

Below is a photo of the current state after round 5 with the Ahhsome. Draining now, and I'll try the cleaning solution you suggest, thanks. I assure you, we won't be using the tub until this disgusting stuff is gone. I'll update after cleaning again and we've given it a couple of days. In the meantime, if anyone reading this post is thinking of buying a hot tub, take my advice, get a smooth shell. We never had a single issue in ten years with our old spa until it just died of old age, and even then, the shell was recyclable.

AG, Thank you so much for taking the time to reply. We have repeated the Ahhsome purge four times now. A fifth dose was added last night. Every time we purge, we have to thoroughly scrub every surface. A cloth will not wipe away the buildup, it only smears. The shell is rough, not smooth. After cleaning and upon refill, you can still feel the stickiness underwater. And as soon as the pump is turned on, a new gunk line starts forming, and the water foams up topped with its own gunk.

We bought an AquaTerra hot tub at Costco about two years ago. We keep it meticulously clean and maintained. A couple of months ago we noticed a sticky film on every underwater surface, and when we got out our skin was VERY sticky. We drained and cleaned it repeatedly with no improvement. Finally, we called the manufacturer who recommended running a dozen or so bottles of Hydrogen Peroxide through the water for a couple of days, followed by Ahh-some. We are now on our fourth treatment of Ahh-some, draining and scrubbing between each, and nasty, sticky gunk is still pouring into the tub. This gunk does not wipe away with a rag. We are having to use a scrub brush, bleach and a lot of elbow grease. Even used the power washer - and the stickiness is still there! What else can we possibly do?!
