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.
