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

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.

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.

Amazing power and gets the job done. Best product I’ve found. I won’t use anything else!

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.

This stuff is amazing. We used it to clean a some glass surrounding a patio that had been baking in the sun. Did an amazing job. I would recommend this product.

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!

I would give this 5 stars BUT the item arrived used. I didn’t use the product until 2 months after it arrived so I missed out on returning it. Anyway, the product itself is great and works wonder in hard water stains on stainless steel faucets. I’ve tried so many products but nothing has worked until now with Diamond Magic. I cannot wait to try it on glass and other areas. I highly recommend it. If you do purchase from Amazon, just make sure to check that it hasn’t already been used.

Have used it awhile, it does a wonderful job

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
