Krud Kutter305475 Rust Calcium and Lime Stain Remover, 28 oz, 28 Fl Oz

I live at the coast and rust is a fact of life. I can soak anything rusty in this fluid and the rust disappears. Marvelous product. It will be in my shop moving forward.

Used it to clean lime deposits out of the toilet. Used a sponge to remove all the water and poured this in and let it soak for a about 30 minutes. Then used a green scrubby and removed most of the lime the first time around. Repeated the process and no more lime

It worked!!!! I don’t typically leave reviews but I’m so mind blown. Unfortunately I didn’t take a before and after photo but my bathtub had a few rust stains that would not be removed. I tried the baking soda and vinegar...didn’t work. Bleach...no bueno. And at first I thought this wouldn’t work either. I followed the directions and applied to to a sponge and started scrubbing...nothing. BUT I got so frustrated I poured the product all over my tub and just left it. Forgot I did that and cake into my bathroom an hour later. To my surprise..the rust stains disappeared. SO UNBELIEVABLY HAPPY about the results! Give it a try if you are having similar issues.

Works great!

Takes the rust off parts. works sloooooow

I moved into an apartment and the Master Bath Tub and sink had bad and very ugly rust stains which frustrated and depressed me! This cleaner is amazing! Within seconds the rust stains were gone! Take a little longer and some elbow grease for the limestone buildup but I am completely satisfied! My bathroom looks as good as new! This cleaner is a miracle worker and well worth every penny!

This really works great. I wouldn’t believe if someone tell this is real. My rusty parts were covered complete and when I deep them in Krud Kutter for about a two days, now my parts without any note of past.

I bought this product to remove the water stains in my bathroom sink. I did not do a bit of good. Waste of money.
