CLR Brands® Lime & Rust Remover, Blasts Calcium, Dissolves Lime, Zaps Stubborn Rust Stains and Hard Water, 22 Ounce Spray Bottle (Pack of 1)

Wow! This stuff works amazing! I live in a rental and the tub was just nasty and had rust streaks on the bottom! It got rid of almost all the rust! I just sprayed down the tub and left it for like an hour, and I barely had to wipe down the tub. It came so clean. The bottle did leak during delivered, but at least they had it sealed up in a separate plastic bag to where It didn’t leak outside the bag. It was super easy to spray. The smell is strong and different, but at least it’s not that strong bleach smell. It was very fast acting. And removed stains almost immediately.

We have really hard water. I usually purchase ZEP products as they are great. However, because Amazon had no ZEP rust remover in stock, I decided to try CLR. I sprayed a corner of the shower and left for a bit. When I came back, the hard water stain was gone! Then I sprayed down the entire shower and went to bed. When I got up, I found a perfectly pristine, white shower!!! The only downside to this product is that the scent, unpleasant that it is, does linger and linger. It's been 24 hours and the smell has decreased only a little. I might add that when I opened the box from Amazon, the CLR had leaked. Both bottles were wet.

Consistently good quality. It does eliminate calcium, lime and rust as stated!! Fast and efficient. I have used this product for 20+ years.

I got this cleaner because I was dealing with hard water stains in my bathroom, and it worked really well. The spray bottle makes it easy to apply, and I noticed results almost immediately. It dissolved the calcium and lime buildup around my sink and shower with minimal scrubbing, which saved me a lot of effort. Plus, it works on rust stains too, which is a big bonus. One thing I really like is how powerful it is. I’ve tried other cleaners that barely made a difference, but this one cut through the tough buildup quickly. I used it on my faucets, showerhead, and even an old tea kettle with hard water stains, and everything looked much cleaner afterward. It’s nice to have a product that actually does what it claims. However, there are a couple of small downsides. First, the smell is pretty strong. It’s not unbearable, but I definitely had to open a window while using it. If you’re sensitive to strong cleaning smells, you might want to wear a mask or use it in a well-ventilated area. Another issue is that for really tough stains, you still need to do some scrubbing. While it loosens up buildup, it doesn’t always wipe away instantly, especially on older stains. I had to go over some spots more than once. Still, for a cleaner that tackles calcium, lime, and rust all in one, this is a great product to have on hand.

Rust stain in bottom of tub from chipped porcelain. Spray repeatedly for 4 days stain completely good. If the would have been full strength CLR it would’ve been gone in one day. With this product there was, No scrubbing, just repeated spraying made it easy solve the problem in a few days. Then i touched the chip with porcelain epoxy paint. Gone for good

Works on what needed it for. Stained plastic and it cleaned it. Be sure to read the directions on length of time to keep this product on what your cleaning. Great price. Very easy to use.

Only good for glass and ceramic - deadly on natural stones and many other materials. Do not recommend as a general purpose cleaner.

Great on stainless steel sink !

Perfect for removing rust
