bought a new house in a somewhat more rural area. every toilet tank and toilet bowl had really bad iron deposits and buildup, so much so that we were concerned that we wouldn't be able to get it clean. purchased this CLR and let it soak in the bowls and tanks, etc and within a couple days of this everything is perfect. Softened water is a must too, but this got rid of that initial buildup common with a place that doesn't yet have a softener.

I have hard well water and the calcium builds up rapidly. I use this for humidifiers, coffee drip makers, shower heads, and in washing machines & dishwashers. Fast work on calcium build up.Glad I can purchase this in gallons finally, the quart bottles are very expensive compared to gallons. It's also safe can be used without protective gloves. Great Product....

I have used this product for many used from rust on the concrete, iron stain on the vihnl siding, staines in the sinks and best of all cleaning the oxidation from the humidifier on the furnace.

It is effective in cleaning and shipping is prompt but the bottle had a small leak from the cap wasn’t tight enough.
