This says it’s for coffee makers, I believe, but it works better than anything else I’ve tried on “warm” humidifiers. They can quickly build up very thick mineral deposits. Can be diluted - 1/3 Durgol, 2/3 water or as weak as 1 to 5. The solution works just as well as undiluted, just takes a longer soak, so this product is actually quite inexpensive. It even works when it’s not in direct contact with scale. My new humidifier’s “heating element” sticks up about a centimetre over the water when the unit’s base is as full as it can be (and of course the solution when I use that). There’s always a “cap” of scale left after cleaning, although I can thin it down by scraping. (It seems to be impossible to turn the unit upside down and soak the element that way!) The last time I cleaned my latest humidifier and put one tank full through, (with that cap of scale still sticking to the element), I thought I’d check to see if I might be able to scrape more scale off when it was hot and there was perhaps a bit of descaler in the solution from cleaning. (It works sometimes.) When I pushed at one edge, the cap just popped off! I’ve used all sorts of descalers with all sorts of warm humidifiers where the heating element can’t be covered completely by the anti-scale solution but the top of it still gets a thick deposit just from the steam. This is the first time the scale came off completely and easily. This product is worth every penny, as a thick layer of scale on top of the heating element makes the humidifier much less effective, until it overheats and quits working..
