CLR PRO Calcium, Lime & Rust Remover - Quickly Removes Calcium, Lime, Hard Water Deposits and Surface Rust Stains, 32 Ounce Spray (Pack of 2)

I had a dripping showerhead for months. Took a long time until my son could replace a part. As a result, there was a lot of hard water and rust buildup. I laid down paper towels, soaked them with the CLR and let it soak for hrs. I scrubbed with a brush and a bunch of the stains came off,. I repeated the process the next day. Perfect. Looks great. Thanks for a great product.

I had some rust stains in my shower and wanted to get rid of them.. I thought I would give this product a try and I have to say that I’m very glad that I did. I sprayed this product directly on the rust stains and gave it about 10 minutes before wiping it off. The result was a nice clean shower. The product came in a couple days after ordering and is very economical to use. I would recommend this product. Amy

I have/had stubborn smoke and rust stain on a lanai ceiling. Still takes elbow grease, extra tough rubber gloves and, plenty of VERY hot water/ bug worked pretty OK

CRO makes good products to clean metals, glass

This was a big waste of money. Did not work as well as original CLR. Subsequent vinegar method did the trick. Three stars is generous for this product.

This stuff works great. I've used CLR for years, but the spray option is much nicer to use than the old gray bottles. I did have trouble with one of the tops...but I just put the other one in instead and will swap it into the 2nd bottle when the time comes. Great deal too

I messed up the inside of my LG stove by using EASY-OFF oven cleaner!!! I forgot to take a pic of the residue because I was so upset & distraught...I went online and found out that CLR PRO will get rid of the residue but the EASY-OFF oven cleaner ate the shine off the blue enamel inside the oven...I used some Meguiars M716 Mirror Glaze to help with the dullness from the EASY-OFF

I was hoping this would work better than Lime Away but it did not. Used pumice stone and scrubbed forever. Finally gave up and used vinegar and water which worked after more scrubbing. One time where cheaper was better.
