16 oz : Water Spot Remover Bring It on Cleaner for Tough Water Stains 16 Fl Oz, Hard Water Spots, Mineral Buildup, Clean Windows, Clean Glass

SUMMARY:If you use it as directed (don't be like me and think you know better), you will be very pleased with the results. This stuff is amazing! I can confidently say that this is the best product I've used (and I've tried many) to remove stubborn hard water stains from my glass shower doors and from my shower tiles.THE LONG STORY:I purchased Bring It On to remove hard water stains from my glass shower doors. I had tried everything to remove the stains with no success (or with some success, but with a tremendous about of effort). A friend mentioned that this might work, so I thought I'd give it a try.When I received it, I ignored the directions and went straight to using it with my drill and a 'hard' pad (not the one recommended by Bring It On). It scratched the heck out of my glass shower door. I was very upset and (of course) blamed it on Bring It On. I wrote a nasty review and returned the product.I just couldn't get rid of this nagging in the back of my brain... 'could it possibly have been MY fault?'.Well, I swallowed my pride and decided to give it another try. I deleted the 'nasty' review and being too ashamed to re-purchase from Amazon, I went to my local Ace Hardware store and bought another bottle (for some reason it was in the carpet cleaning section... weird).This time I used it AS DIRECTED (on a non-abrasive sponge and NOT with my drill). Wow! Years of hard water stains (from lazy renters) is gone... and no scratches! It takes a bit of effort, but much less than anything else I've tried. I'm looking forward to finishing up the shower (I'm taking a break right now because my arms are tired). The areas that I've completed have returned to their original clarity (I'm so happy).

I have used so many products and DIY concoctions to try and remove soap scum off my shower door. This stuff is amazing. It took no effort at all. I am thrilled to have found something that finally works.

This product required little elbow grease, but did the job! I used it on my cabin shower stall that yellows because of the well water. I was very pleased!

I own an AirBnb and we used this for our first deep clean. It is hands down amazing! My regular cleaners now use it all the time. Our bathrooms sparkle!

I’ve never felt compelled to write a review, but this stuff is amazing. I’ve had hard water stains accumulating on my faucets, sinks, shower glass, you name it, for the past 5 years. I’ve tried EVERYTHING. This took care of it with minimal effort. Fantastic product.
