Cleaning and work well

This stuff works! I hadn't cleaned by water heater in a long time - a bit more than a year - and tried some of the homemade remedies that I saw online (vinegar, lemon juice, etc.) and those methods just didn't really work in getting rid of any of the scaling on the pot.So I bit the bullet and spent the money for this. It feels like it's more expensive than it needs to be, but the fact that one application worked perfectly in taking off ALL the scaling and cleaning the pot, I'm going to say it was worth it. But since the de-scaling really should be done every 3 or 4 months and not once every 15 or so months, it's a pricey bit of maintenance.So, I gave it three stars for value simply because it will become a costly maintenance device. And maybe some of those homemade remedies would work if I did them every months instead of waiting for the amount of scaling I had built up, and then use these just once in a while to give it a serious cleaning.I rated it five stars on taste not because I tasted it - I didn't, and you shouldn't: it's not food - but because I didn't want the taste rating to affect its overall rating.Does it do its job? Heck yes! Supremely well.Is it a good value for the money? That might be up to you to decide.

Easy to use, clear instructions and it works
