Oh Yuk Healthy Hot Tub Cleaner, Hot Tub Cleaner for Indoor and Outdoor Hot Tubs and Spas - 16 Ounces

Worked very well in a 400 gallon hot tub with some biofilm build up. If shock, sanitizers, enzymes, and conditioner aren’t keeping your water, then it’s time to replace the water. Do yourself a favor and use this product before emptying. No colored residue like other products, and leaves the tub feeling incredibly clean.

Awesome cleaner! It does the job that’s needed for each season when it’s time to clean out the hot tub! Super easy directions.

This stuff really works! I put half the bottle in as recommended and it went to work. It Cleaned the hot tub jets really good loosened up the gunk. Let it run for an hour and then I drained it. Then I used a bleach to clean the surface of my hot tub. Smells good when using the product. I refilled my tub and it’s so clean now. I recommend this when draining. The tub every 2-3 months

I was surprised how great this worked! I’ve been using Spa Purge for years and Yuk Cleaner was faster, cleaner and less expensive to use. My tub went a few months between cleanings and this did a great job. I’ll be stocking up.

Arrived very quickly and works great. I use it every 3 months when I drain and refill and it cleans extra well. Love it

Bought this to clean my hot tub. It cleans well and instructions are easy. Make sure you rinse out your hot tub thoroughly after use. This 1 gallon jug has plenty of product to clean your tub multiple times. Store it some where safe. Good value for the amount you get.

I have cleaned the plumbing on a regular basis so I didn't have all of the bad looking scum the other videos did. It says to use 8 ounces, and I noticed a 8 ounce mark on the side of the bottle making it very easy to administer the proper amount. I do believe it did a good job, my wife had commented that the towels I dry off with after using the spa had an odor. While using this product I did notice when I ran the jets the water got very white in color and foamy. Since I used this product, my wife said the odor is gone.

It worked okay. Still had to pull out each jet and clean the stuff that remained. Does take a bit of scrubbing to remove the residue left behind. I had used it once and will try the other half of the bottle on my next drain.
