Water Spot & Multi-Purpose Cleaner (20 Ounces) Clean with The Power of Genuine Diamonds! Professional Cleaner/Hard Water Stain Remover. Made in The USA!

Have tried everything I could think of to get hard water stains off of my glass shower door. All required hard work and still didn't do the job. I have a waterproof shower scrubber. Put some of this on the scrub pad and went to work on the doors. I wish I had found this sooner. No harsh smell and truly got rid of the water stains. Alot of the product is not needed however I am getting a second bottle in case I can't find it online again. Seemed costly when I purchased it but worth every penny. I highly recommend this product.

This is the ONLY cleaner that got hard water spots off of my exterior windows! Before I got my front yard sprinklers adjusted, that irrigation water was spraying all over my front windows. Nothing else worked to clean off the hard water - vinegar, Mr. Clean sponges....then I found Diamond Magic online recommended by a professional window cleaner. Make sure you follow the instructions exactly. I found it was best to remove my window, lay it flat, use cleaner as instructed, wipe off the initial residue, then I carried the window to my bathtub and gave it a final rinse. Again, this is serious stuff, so make sure you follow the directions on use.

Had hard white marks on windows from irrigation system recycled water. This stuff made it pretty easy to get rid of the marks with very little elbow grease!

After testing this cleaner on hard water stains on glass shower doors and chrome faucets, I'm impressed. The micro-diamond formula effectively dissolved stubborn white spots that other cleaners left behind. A little gel goes a long way; the 20-oz bottle will last. It requires some rubbing and rinsing, as a slight hazy residue can appear if not wiped thoroughly. The professional-grade power is evident, but it's not a zero-effort product. For the price, it delivers genuine results, making it a worthwhile solution for tough bathroom and kitchen stains.

The best I have found for hard water scum on glass shower doors.

Have used it awhile, it does a wonderful job

I was excited to receive the Diamond Magic. The first thing I noticed was the smell. A chemical smell I can't place. If your clothe is too damp the cleaner thins too much and became liquid. Be sure to have a large rinse bucket (2gal min) and a good sponge to quickly wipe off the haze. It states it on the bottle and they mean it. I hade to wipe multiple times and continued after changing the rinse water. I finished the stove with multipurpose orange oil cleaner. My goal was to get the water spots off the stove top and some of the burnt on gunk carbon around the burner. I bought it this way and expected to put some elbow grease into it. Just not this much to get do little results. Truly, this "diamond" abrasive is disappointing. Save your money.

Excellent. Removed water stains quickly with little effort.

Bought this to take of a couple of years of water staining on basement windows. I wish I had taken pictures, because the windows had a heavy calcium deposit that nothing else could get off. This stuff worked like magic!!! I am nervous with any product on windows, I'm always worried about scratching. This cleaner did wonders! Being very careful to follow the instructions, we carefully did a few applications and was able to get 99% of the buildup cleaned off! We may try again later this summer and see if we can get that to 100%, but we are so happy with how it worked. There was no scratches or marks on the glass, just clear and clean! This product is not cheap, but if you have a difficult buildup and worry about your glass, THIS WORKS! And we used very little of the bottle and still have much left over for other applications. Bottom line, if you are particular about your windows, this is the product you want.

I have used this on just about everything. It removes stains and makes things shine. Use only as directed

did not work for my shower door … had very high expectations
