A few years ago I was browsing at a store when I remembered I needed toilet cleaner. I grabbed a bottle of The Works toilet cleaner which I had never used before. Took it home and I was impressed with how clean it got the toilet so I've been using it ever since. Fast forward to last night. I wanted to clean my garbage can so I took it up to soak it in the bathtub. I usually keep a bottle of bleach up there for household cleaning but must have used it all. Not wanting to go down to the basement I decide to use this toilet cleaner instead. (It disinfects right?) So, I start running the tub and squirt some of the cleaner in. While I do this it hits some stuff that has been on the tub forever and it starts fizzing. So, I took out my sponge and wipe it and all this stuff comes off. Now, I am intreaged and I read the bottle that says "removes soap, lime scale, and hard water stains." Today I go up to finish my garbage can job and let the water out of the tub and more of this stuff is coming off. So, I drain all the water, take the garbage can out and pour more of The Works in the tub and to my amazement it removes everything that has accumulated in the tub! I have lived in my house six years and I have never been able to get the tub cleaned. I have tried CRL, comet, soft scrub, pretty much everything. I have scrubbed it to the point that I could be on that commercial with the ladies with the arm braces. Nothing worked. It was so "bumppy" that I thought some of the finish was actually coming off the tub and that is why it was like that. It was gross and embarrassing but we had to deal with it till we had the money to replace it. I can not believe this stuff just took it right off in a matter of minutes and I didn't even have to scrub it. It just wiped right off. Now we don't need a new tub after all. I am so excited I am literally leaving right now to go buy the regular cleaning product of it so I can try it on the shower door. If that works even half as well it's bye bye comet and lots of other cleaning products I use. I just had to tell someone how great this stuff is and thought you all might like to know.
