This product is great for cleaning homes who want a biodegradable product that is not harmful to pets and children , gets hard water stains and rust out of just about any thing . Spendy but lasts a long time .

Love using this product for cleaning shower glass doors. Gets the hard water stains off first try. Its my go to for my cleaning business.

Just great!

I thought this would be about as good as what Ive always used. totally surprised at how well it worked.

I still can not get the hard water stains off the bathroom glass showers and I even use a drill with a sponge to try and do a better job, but it doesnt quite do the job. Disappointed, and not sure what to try next.

It worked on the metal parts of the shower system but worked partially on the glass shower doors

I wish I had taken a before and after photo! Our old shower door just never seemed to get clean. I tried lots of different products claiming to remove hard water buildup and/or soap scum. This REALLY worked. And it did not require a lot of elbow grease. Seriously, its magical. As a bonus, it didnt smell harsh at all. It smelled just like Pepto Bismol... slightly minty. I called my husband upstairs like 10 different times to be like Wow! Look at it! Our house is 25 years old and in the 4 years that we lived there, the shower door has been unsightly no matter what cleaner I tried. Now it looks like new!

We have very hard water where we live, and I had tried several things to remove the hard water spots from my glass shower door and side wall. The house is about 20 years old, though we have only been here 6 years, the previous tenants werent exactly meticulous about cleaning. Tilex, vinegar, etc., nothing worked. The vinegar works fine if you can soak an item, but spraying it on a vertical surface was just not effective. Finally tried this stuff, and my shower looks about 95% clear, with a bonus that the water sheets off of it nicely now. It does take some elbow grease, but I did it in stages over a couple days and it really wasnt that bad. I took off a star because it really didnt touch the gross yellow crusty build up at the base of the door that no amount of scrubbing or product of any kind seems to touch. I may try a scrub brush drill attachment if I can find one, and see if that works.

To say that my place has hard water is an understatement. Sometimes, it surprises me that the water doesnt just plop out in flakes or chunks. The large sheet of safety glass for my bathroom shower accumulates hard water deposits might fast. Like, should I fail to squeegee the water off of it for a couple of days, it looks like someone tried to tag it with spray paint. Rolled the dice on this product and WHAMMO!! Hard water stains were destroyed with one application (I still need to go back and do a bit of touch up). Not only that, but the scent is kind of fun - think Christmas peppermints mixed with Pepto. It worked so well, and with such a modest amount of product that I think I may ever try to clean the hard water stains off of the tile in the shower!

You can scrub until your arm falls off but if you’re not using an effective product, it doesn’t matter. So I tried this stuff and I got the ugly water stains out of the toilet. Easily! Finally! Highly recommend.
