We recommend the following instructions: 1. Empty your water cooler, including the reservoir and all lines. 2. Pour H2OK into an empty water bottle. 3. Fill water bottle with potable water, but only enough to fill the reservoir. The H2OK and potable water should not exceed the reservoir capacity. 4. Install the water bottle and allow the reservoir to fill. 5. Wait for 15 minutes. 6. Drain the water cooler through the outputs. (In this case, through all three hot, room temp, and cold water outputs) 7. Refill your empty water bottle with clean water and allow the reservoir to fill again. Drain through all the outputs. 8. Your water cooler is now clean! **Q: What percent of hydrogen peroxide is in your solution? Can you be more specific about the difference between this and 3% hydro peroxide?** A: The specific formula would be proprietary information. If you are wondering how it differs from 3% peroxide on the drug store shelf? The strength, blend, manufacturer, and stabilizer package is how ours differs. The peroxide on the drug store shelves is for general use or cuts and scrapes. Our was designed and created solely for biofilm due to stagnant water. **Q: Is this just regular drug store 3% hydrogen peroxide?** A: That’s a great question! No, it is not drug store hydrogen peroxide. There are so many manufacturers, types, strengths, and proprietary stabilizer packages, each blend is designed for a specific purpose. (The stabilizer package alone can change everything!) Pristine H2OK was designed for your water cooler. Through extensive testing, we have found our formula works the best! **Q: How much clean water do I mix with the entire contents?** A: You just pour the entire contents of the bottle into the dispenser, and let it sit a while, and then after draining it - you pour fresh water into the dispenser to flush it all out ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great cleaner! *by T***E on September 16, 2025* 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! ### ⭐⭐⭐⭐⭐ Lots of rinsing *by R***E on December 20, 2025* Cleaned water cooler really well it runs much smoother now. But I had to rinse it multiple times to get the taste out. ### ⭐⭐⭐⭐ Works well but I would buy a couple just in case.. If it’s gross you’ll need 2 like I did *by S***D on October 17, 2025* 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. ## Frequently Bought Together - Pristine H2OK Water Cooler Cleaner - Dettol Washing Machine Cleaner Lemon, 250ml… --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/154575611-h2ok-water-cooler-cleaner](https://www.desertcart.pl/products/154575611-h2ok-water-cooler-cleaner) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-27*
