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

I LOVE this cleaner. My hot tub had a black ring at the water line, due to me not keeping up with the chemicals properly. As I drained my tub, I sprayed this and let it sit for maybe 30 seconds. With just a microfiber towel, it removed every bit of it. Very impressed. It does not have any odor, which is also nice. Highly recommend this product for cleaning your hot tub shell.

The EcoOne Deep Clean Kit is fantastic! The scent is pleasant and not overpowering, making the spa experience relaxing and enjoyable. Everything feels fresh and clean afterward, and the kit is easy to use. High-quality, effective, and a great way to pamper yourself at home—highly recommend!

This cleaned my filter pretty quick and efficient. I usually soak one filter while I use the other. It doesn't seem to hurt the filter to sit in the solution for a couple weeks.

My blow up spa was a mess this year because I’m a lazy girl sometimes and I think things will magically fix themselves. Allllllll spring and summer long I didn’t clean out my hot tub. Why? Great question. I thought if I left the tub filled with the lid on and turned off the heater and just ignored it, it would magically be perfect in 6 months with a spritz of chlorine or something. Now I know what you’re thinking… so Hold the judgement you gargoyle. I’m a self-proclaimed busy girl. You will be shocked to hear that when I finally opened my hot tub lid, it actually looked ok. I BEAT THE SYSTEM?! But wait…. Wtf is all this slimy, booger feeling film everywhere?? You guys… Like JELLY. Like … effing kill me now. Hot tub - 1 me -0 I considered returning it (thank you Costco return policy) I considered selling it as is. I considered just buying a new one. Until one day, I got mad at my partner. And Guess what I was about to target to clean with a vengeance?!?! I researched a ton. I landed on this cleanser. I cleaned everything in that hot tub out. Everything top to bottom. All the holes and jets and pipes and other part words I don’t know and never will know. It was nice that I didn’t have to clean my cleaner out (all natural), And it didn’t stink. Voila. It worked. I have my hot tub back. Buy it if you have a jelly problem. The end.

I read a lot of reviews and didn't want to have to wear gloves. I started by cleaning with baking soda which worked well but didn't clean the harder stains so tried this and with very little scrubbing it got rid of everything. Wish I had pictures of how bad it was! Probably don't need to start with the baking soda next time and just use this. No smell, no gloves, easy peasy.

The item is much smaller than I anticipated. I did not pay close attention to the amount of product in the bottle must use sparingly.

Shell clean really does the job, makes them shine and gets rid of topical dirt and grime

Love this filter cleaning formula! Never foams up or leaves a residue in my hot tub after cleaning the filters.
