Review: Excellent product for experienced DIY'ers - Second year of using this product to descale my Navien NPE-180A2 unit. Year 1 of doing the flushes myself, I mixed up the necessary amount of solution per the dilution rates and followed the instructions for how to flush my system. In total, took about an hour with the flushing process being about 35-40 minutes. The amount of material this solution was able to remove. I remember seeing what the technician got out on the very first flush done on the system and I feel like this removed a lot more. Year 2 of doing the flushes myself, similar results and time it took to use. Extremely happy with the product and results.
Review: Excellent solution for descaling the worst mineral build-up inside tankless water heater - Works great. This product saved me thousands of dollars! I used it to clear out scales from a tankless water heater that appeared to be beyond repair. We bought a new house with a tankless water heater and did not realize that we also needed a water softener until about five years later. Once we almost completely lost hot water, a repair man told me the only solution was to completely replace it for multiple thousands of dollars. I decided to ignore his device and using Youtube and watching him, I was able to figure out how to use this descaler and a small pump to clear out all the mineral build up. The instructions said not to go more than 30 minutes, but I did 4-5 hours for 3-4 different days. Each time the "hot" water got a little warmer. Eventually, I got the hot water to work completely. With our new water softener system and this product, I think I solved the problem. This product saved me thousands of dollars!

## Questions & Answers

**Q: For the seller only, please: Would you recommend this product be used to effectively descale a countertop ice machine w/a built-in water line?**
A: Yes, this product is great for descaling water lines with mineral buildup. If the ice machine has buildup inside the waterlines this should effectively clear those lines.

**Q: Will this work for an LG front-loader washing machine? I need it to clean the pump, tub, and drain lines.**
A: I would not trust this product on heavy buildup.

**Q: for 40G tank how much I need?**
A: You should rig up a pump and let it circulate for about 45 mins.

**Q: What is in this besides hydrochloric acid? My tankless water heater manufacturer Rinnai seems to only recommend vinegar, no harsh chemicals.**
A: I do not know other than what's on the label, but I have two Rinnai units and have used it on both, two times now, adn have not seen any ill effects.
