## Description

desertcart.com: QwikDescaler+ Concentrated Tankless Water Heater Descaler Solution (1 Gal) | Descaling Solvent for Tankless Heat Exchangers & Water Heaters, Quickly Dissolves Scale, Lime, Tarnish and Deposits, 1 Gallon : Health & Household

Review: Works Great. Well worth money. - Previous house owner never flushed the tankless water heater and it stopped working. REN this stuff through for a few hours and it brought the heater back to life. The following year I tried to save some money and used vinegar. Thought it worked but when I recently flushed it again this year with this stuff and the water turned black. Increased water temp by 3 degrees. Only using Quuckdescaler from now on. This stuff works great.
Review: It works - Good product. It’s concentrated and mix 1:5. Because of my pump came with bucket and minimum level required a little more then 6 quarts, I had to add about 1 quart more eater which deluted descaler a bit more. But instead of running prescribed 30-45 minutes, I run it for 60 minutes. The cloudness of solution started to come in in about 20-25 minutes which tells me the solution started to work. After 60 minutes of continuous cleaning, there was some brown sediment and some sandy deposits in a bucket. Job done well.

## 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.
