H2OK Water Cooler Cleaner

Cleaned water cooler really well it runs much smoother now. But I had to rinse it multiple times to get the taste out.

My primo water dispenser was starting to come out slowly and I knew it was way overdue as I’d never done it before. 🫣 this was so easy to use and didn’t change the taste or anything! I’ll definitely buy again when needed!

I got a Primo 5 gallon that had algae in it and obviously I didn’t realize till I tasted the nasty pond water taste and smell… Well I tried many vinegar-water mix flushes and it just had straight vinegar taste/smell after liters and liters of flushes, I must have made it too strong idk. So like an idiot I just stopped using it and let it sit for a couple of months and just used store bought spring water. Well there were gross floaty things in the water when I flush it again so decided to give this a try, worked well! I needed to get a second bottle of this solution to completely get rid of it but well worth it. Water tastes great again and is clean visually. Wish they made a larger size that has like 3 uses for $20.. October 2025 this stuff is $10 for one use so kinda pricey But it is what it is. Every few months I’m going to buy one and flush the tank.

Our water cooler was mildewy and the water tasted gross but now it is clean and refreshing again. Great value will buy again to keep it clean.

I was skeptical about this product, I never leave reviews, so I had to come to say that this us by far the easiest way to clean your water dispense. Prior we were running vinegar through every new bottle or two and that usually cured the inevitable “off” taste that shows up in your water dispenser. Recently though vinegar stopped working so I resorted to this and wow. It is so much easier and our water tastes perfect. So happy.

Great product works

This water cooler purifier works great and was easy to use. Our shop water cooler developed a moldy taste and smell, which we had to address. Following the product directions, it was quickly remedied. Highly Recommended! CFH

It's just hydrogen peroxide with stabilizers just like you can buy almost anywhere for $2. Stabilizers leave a smell/taste. Instead by a jug of 12% food grade and dilute and make 40x the amount sold to you for this product for $10. Highly disappointed.
