This really does the job of taking off years of calcium build up. I've used several different products to remove calcium and I was stuck scrubbing the same spot for 15 mins. This wasn't the case for CLR I sprayed my shower walls without diluting the product two times and let it sit for 5 mins. And The calcium build up wipes right off with a non scratch pad.

Wish I found this sooner

Easy to use. Put some on the scale around my bathroom faucet, let it sit for 20ish minutes while I did other things came back, scale came off with the sponge.

Happy

Great product been using for years to remove calcium off plumbing fixtures follow the guidelines and have a little common sense and you will have success the product.

Professional SWF Plumbing Service Technician

Great product. Shipped without sealing tape over lid. Had food items. Left stain on carpet from leaking box.

Living rural we have hard water from our well even though we have a water softener occasionally, the water softener needs cleaning and you'll notice a buildup of rust in the shower, sinks, and toilets. 
First love the spray options on the bottle you have a mist for close-up jobs , the stream for reaching the shower walls so you don't have to put your head in the shower, breathing the fumes. The smell is pretty strong, I advised people to cover their mouth with a clean cloth or mask, do not breathe the fumes and have your windows open, some sort of ventilation. 
It did an excellent job without scrubbing! I sprayed our white shower let it set for 15 minutes, rinsed it off, repeated it looks very good. My Husband's bathroom has a white porcelain pedestal sink, 28 years old , made the sink look awesome again no scrubbing. Used on the white toilet in my husband's bathroom. It looks brand new.. finally a product that works without scrubbing, only negative is the smell is strong.

Works awesome no scrubbing

[This review was collected as part of a promotion.] I can't believe how well this worked on the old toilets in our house! They've been stained in certain spots since we bought the home, and two rounds of this finally got them clean

This worked amazingly on rust stain in my tub that has been there for a while because I was waiting for a remodel. I was finally able to use CLR and only sprayed once and the stain is gone! Yay!!! Thank you! I will be constantly using this also for calcium deposit removal as it works awesome on that too!

Really works!

I had a container with serious thick calcium deposits. I tried scraping and scratching it off, unsuccessful. My last resort was CLR. With one use (following package instructions) it removed about 75% of it. I still did try chiseling the rest off and it came off much easier. Just a small amount remains. I'm very pleased.

Pleasantly surprised

Has this item been super diluted, changed formulas!? Inquiring minds would love to know!? I've used this religiously on tough lime scale and rust over the years for hard water stains and build up on porcelain, steel etc… you get my drift! I recently bought some to try and remove some rust stains from vinyl siding. In the past it's worked like a charm. A little scrub, rinse %26 repeat, like magic, done! ✅ Now, I find myself through the whole bottle (which generally a little goes a long way) and hasn't even begun to remove a lick of that stubborn rust! I don't know if it's the formula but, what I can say it's not human error! Calcium, Lime and rust be gone? Only thing gone it my money!

Stains might not disappear but, your money will!

I got more rust off using coke... I followed the instructions and it did basically nothing.
