CLR Calcium, Lime & Rust Remover, Blasts Calcium, Dissolves Lime, Zaps Rust Stains, 28 Ounce Bottle (Packaging May Vary)

This is the only thing that has been getting rid of the lime stains in my toilet bowl. The directions say to empty the water out of the bowl, but I don't know how to do that so I've just been pouring some into the bowl, wait a few hours and scrub and flush and little by little the lime is going away. Highly recommended.

This CLR calcium remover works great. I have used this product a few times over the years. The bottle is easy to handle. The product pours out safely and does not splash. I love that the product works extremely well. I am very happy with this CLR calcium remover.

Cleans great. I dump some in the toilet overnight

Cleans toilet well after second try. Needs a little scrubbing for mineral stains.

I posted a review a few days ago and it's been removed. So I'll keep posting until it sticks.I noticed a few months in I started getting rust stains on the driveway beneath exhaust pipe.I bought CLR twice, (two applications, followed instructions and it didn't work. Later, I did some research on Youtube and it seems others had the same experience.I'm giving it 3 stars b/c it does work a little for light rust on hand tools (screwdrivers) etc, (decided to try what was left on those, as I didn't want to "waste my money" but as far as the driveway (the reason I b ought it) just didn't work.

We applied fertilizer to our yard and some of it blew onto a joining concrete. A day or 2 later, we notice horrible rust stains on the concrete and was devastated. New home, new concrete. Searched the web and found CLR. Bought a 28 oz bottle of CLR to test what it would do. Applied nearly the entire container in an area about 2-3' x 4-5'. Put it on and scrubbed hard with a stiff garage floor broom. The directions said it had to be removed in 2 minutes so that's what I did. I then pressure washed the area and about 50% of the rust was gone. Very disappointed so I gave it another shot. This time I left it on for 3 minutes with hard scrubbing. Then pressure washed it off and I would say 98% or more of the rust is gone.Pressure washing by itself did NOTHING. If I hadn't used my pressure washer above, not sure if I would have had the same results. I have an electric SunJoe pressure washer that I've had for about 5 or more years and it still works great. Lower pressure than most gas units (2000 psi verses 3000 psi). I rate this unit better than the 2 previous gas washers I've had. NO gas to buy, less noise and my gas units just didn't hold up like my SunJoe. Disclaimer, I don't use the SunJoe that much so don't know how it would hold up with more frequent use.
