    So far so good. It seems stronger than vinegar. The price was fair. Wear gloves and eye protection. I wish the directions for disposal was more detailed.

    Worked very well in cleaning my Rinnai Tankless Hot Water Heater. Only recommendation is that you follow the instructions specific to your model of heater vice simply using what is written on the Calci-Free container. Though very similar, a longer flush time is recommended along with a more robust back-flush rinse.

    After only 5 minutes of back flushing the on demand water heater I could actually see some calcium deposits floating around the 5 gal. pail being used to hold and pump the solution. I waited about 2 years to flush the system and after I was done, approx. 30 minutes, there was a considerable increase in the volume and pressure of the hot water being produced. Will do this every 6 months now that I see the positive affect it has.

      We paid the plumber the first time to de-scale our tankless water heater, but bought the pump/setup. Now do it ourselves. This is the only thing to buy for each service. Since our Alkalinity/Hardness is about 100 mg/L (ppm), once a year will keep the heater functioning at peak.
