Shell Cleaner by EcoOne | All-Natural, Fragrance-Free Spa & Hot Tub Surface Cleaner | Hot Tub Shell Cleaner Removes Scum, Grime, & Stains | Foam-Free Spray-and-Wipe Hot Tub Cleaner, 32 Oz

Where do I start?!? I could go on and on about this product. However, since it was so extremely easy to use and it works exceedingly well, I’ll keep it quick just like this stuff does on my hot tub.It’s basically spray it on and wipe it off. No need to let it sit at all. It works like window cleaner does, fast and clean. Only one spot took a little elbow grease in the filter box where the gunk builds up. It was really no issue to do at all. No rinsing needed either!So, I cleaned the hot tub after the summer when I drained it and it sits for 4 1/2 months. It took me about 20 minutes total on my 6 seater tub to clean it all. This includes cleaning the entire shell and the cover.I HIGHLY RECOMMEND THIS!

Works well with light scrubbing, removed hard water and calcium lines

Used this for the first time after draining my 6 Person hot tub. Cleaned the entire shell and used about 2/3 of the bottle. Would recommend this cleaner and will purchase again.I was previously using a mild soap, but I felt like it was leaving soap behind on the shell. Compared to this product, almost no foam appeared after filling and running the hot tub. The only foam that appeared was due to the oil on my arm from testing ph, alkalinity, etc.While it is expensive, overall I am pretty happy with the product and will likely save me time and money by not having to add chemicals to handle the soap residue.

works well, leaves a lot of residue and needs a hose rinse

cover leaks and does not clean as well as expected. Don't waste your money.

Did a great job cleaning the scum off of my Jacuzzi tub. Didn’t have to drain the tub to use it. Some areas needed a bit more soaking than others, but only took an extra minute or two for it to work. Highly recommended!

This product is amazing! I used the EcoOne Filter Cleaner on my hot tub filter after having not even rinsed it for at least six weeks. It was pretty disgusting. I really wish I'd taken a photo of it before cleaning. I let the filter soak overnight, gave it a light rinse with the hose and now it looks like a brand new filter! I've tried other filter cleaners, and have been disappointed by all of them. I was thinking that I might be better off buying a new filter every time I changed the water. I'm so glad I tried EcoOne! I love that it's Earth-friendly and it doesn't cause any foaming in my hot tub. This is good stuff!

The sprayer leaks up through the stem - no way to prevent. It will leak out if not kept vertical. Perhaps this is an isolated occurence but I would not buy again. If you can't get your packaging right, I don't have not confidence in product.
