Perfect for removing rust

Not like magic but did get rid of iron stain pretty well ~ 25 year old tub and shower. I did apply it several times to my shower and tub and~ I used a wide car brush with extended handle ~lightweight and easy to apply the CLR and then rinsed with cold water. I can’t say what might do a better job. But this CLR is safe to use and the smell was okay. I only noticed a little reaction in my nostrils after using. If you are cautious or allergic do use a Mask.

The product worked very well and did not leave a nasty smell when in use! Easy to scrub off hard water stains. Will definitely purchase again!

It works so well, I should have gotten a gallon. Stainless steel shines after CLR exposure, really works good, even on things 100 years old. Be careful it's powerful keep your distance. Wear rubber gloves for your own safty

This cleaner works well with limescale but needs some time to work on stubborn buildup. Minus one star for its smell - it’s horrendous, it smells acidic and pungent, it’s better to apply it, then turn the bathroom fan on and leave for a while. Otherwise, you’ll end up with a nasty cough and feel like you inhaled vinegar.
