Works very well.
I have used vinegar to clean my tankless water heater. It probably worked a little. I tried this product and it was much more effective. Cost wise probably the same as buying a lot of vinegar, but easier to use, dispose, and more effective. I will use this going forward to keep my heater in good condition.

Empecemos a tener variaciones en el flujo y consistencia del agua caliente. Despues de diez años me di cuenta que el calentador necesitaba ser descalcificado cada año.En el internet recomendaba utilizar vinagre. Tal vez vinagre funcionaria usandolo desde un principio pero con el sarro acumulado a travez de 10 años. no fue muy efectivo. La foto con el agua verde es vinagre despues de circular por una hora. Si salio unos cuantos granos pero casi nada. Con Chromex si se nota la diferencia. La otra foto es una hora circulando solucion con Chromex. Salio mucho mas sarro. Ya no varia la temperatura del agua caliente y no se apaga solo. Pienso volver a hacer la limpieza en unos 4 meses mas a ver si sale mas sarro. Muy recomendado. Doy 4 estrellas y no 5 por el precio.
