CRL "Sparkle" Cleaner and Stain Remover - 8 oz. Bottle

This is a totally awesome product! I live in the country, where hard water deposits from sprinkler overspray have wreaked havoc with my windows. After trying just about every home remedy known to the internet, I came across a piece of advice that was worth its weight in gold: Buy a bottle of CLR!I'm here to tell you that this stuff really works! It took a couple of applications to cut through 10 years of hard water marks, but my windows look spotless for the first time in years. I was so impressed that I proceeded to do all of the windows in my home--a task that I ordinarily avoid like the plague because I'm never happy with the hazy, streaky result. And once again this product did not disappoint. For the first time in many decades of window washing, I have glimmering, streak-free windows, and with a minimum of effort.Notably, this product is not like any other window washing product you may have used with a squeegee or with a spray bottle and a roll of paper towels. It is a thick lotion that goes on like a liquid car wax. You apply it with a damp cloth or paper towel, let it dry, then wipe off the residue with a buffing motion. The process is really very much like applying wax to a car, but much more quickly and with way less effort. And the shine--oh my goodness! I really cannot say enough good things about this product, which has taken the angst (and the failure) out of window washing for me. I'm anxious to see what it does on my bathroom mirrors.I should mention that I'm a real Amazon curmudgeon who rarely gives rave reviews. But this product has truly earned one.

Worked better than expected! I bought a rear hatch window for my 1984 Firebird from a junk yard, sight unseen as it was about 2000 miles away from where I live. This must have been sitting in the yard for over 20 years. It was dirty, and had white streaks in it that no amount of Windex would remove. I thought all was lost. I saw a review of this and decided to give it a try. With little to no effort, this took it all off and the window looks new! It's a liquid, not a paste, so it goes on easily and comes off just as easily with very little effort. No polishing, just wipe it right off. I am very pleased with this and highly recommend it. It will NOT take off scratches, but that's not what it is made to do. If it works this good on a 35 year old rear windshield, imagine how well it cleans just a regular window or shower door!

I bought some beautiful, deep blue glasses at a consignment shop but upon examining them more closely at home, I found half of them had quite significant hard water stains that scrubbing was not affecting even slightly. I searched around and tried the recommendations I found online to use diluted vinegar, and that helped a bit on some glasses; on others, it barely made a dent. That sent me in search of the next option, and searching brought me to CLR. I gave all the glasses a hearty scrub inside and out with CLR using just a few folded paper towels, and they came out absolutely sparkling, with the haze and iridescent cloudy patterns completely gone. It was a very satisfying task that did exactly what I needed. Perfect for my needs.

I bought this product to use on clear antique glass. The interior is cloudy and none of the home suggested remedies worked. Unfortunately, neither did this product. It made absolutely no improvement. Maybe it works for some, but it was a total failure for me.

watched lots of reviews saying this can remove etching on glasses. It did not at all. I am not sure if it works for other purposes.

Works great. Cleaned up old car windshields. Word of caution, if you have a lot of knicks or chips, this will go in and fill in white. May make it worse that it was. Overall cleaned the haze off nicely.

Removes 100 years of buildup and etching on old windows. Rub it all over then wait for it to dry (5-10 min) before wiping off. It should turn to fine white powder when removed. If you don’t wait for it to dry it doesn’t work!

Just remodeled my master bath with a walk-in shower with a glass panel. After it was done I tried to clean the glass panel because it was hazy and had hazy lines from cardboard packing. Nothing worked. I was ready to call the contractor to remove it and get me new, undamaged glass. I decided to do a web search to see if there was some way to remove the haze. Found Sparkle and watched a video demo and read reviews. Decided it was worth a try. I’m very happy I did! This stuff turned my ugly glass to a sparkling thing of beauty and it very quick and easy to use. I’m a 74 year old woman who did this myself. If I can do it you can too.This is an unsolicited honest review of my actual experience.
