CLR Calcium Lime and Rust Remover, Multi-Use Household Cleaner, EPA Safer Choice, 28 oz

We purchased this for the 1st time since Clorox didn't work at all. This product we used on hard water stains in the toilets and it was bad. But this chemical worked and fixed the issues. We haven't used it on anything else yet. But we said goodbye to Clorox and Hello CLR we need to keep this in our household and at work too. We will add this to our future shopping list. Also tired on the shower heads and it removed things too..

I bought CLR hoping to get watermarks off a glass shower. It does take some of the marks off, but requires multiple applications and still, I have marks; although not as bad. I was hoping it would wipe right off, but that is not the case.

I live in this old studio cottage with an old toilet and it was not flushing. I didn't know what in the world was going on and I figured I'd have to buy a new toilet until I saw this video online and someone was telling me at the bottom of the toilet bowl inside is a little water jet and, unbeknownst to me, that little water jet was filled and clogged up with calcium deposits. it wasn't allowing the water to flow through to push debris down through the pipes. so I grabbed the bottle of CLR and I poured half of it into the toilet bowl as well as summon to the toilet tank. I let it sit for a few hours and, when I came to check on it, the CLR had broken down all the mineral deposits that were clogging the water jets not only all around the top part of the inside of the toilet bowl but it also cleared out all that build up that was clogging the drain tube in the bottom of the toilet. my toilet now flushes like it's brand new. I would strongly recommend that you pick up some CLR if you are experiencing calcium lime or rust build up on your toilets or showers and I also recommend that you join Walmart Plus because it's a great program with great benefits, free shipping and free delivery for groceries.

I installed new toilets at my house and one of them almost immediately got a stain on the bottom of the bowl. I tried several toilet bowl cleaners that were no better than using plain water. Nothing would touch the stain. Followed the instructions and removed the water from the bowl, poured about a half cup of this in the bottom, gave a little scrub and it was gone. I let it sit a couple of minutes, flushed and it looks brand new again. Great stuff.

It didn't work/help, toilet water tank is just as rusty as ever, it's not all that old of a toilet/tank, but it is so rust stained inside the tank that I thought CLR would do the trick, but to no avail, no change whatsoever, oh well, I wasted $6.00.
