Adam's Polishes Water Spot Remover - Hard Water Stain Remover for Glass, Shower Doors, Paint, Windows, Car Detailing | Calcium, Magnesium & Soap Scum Remover

This product is amazing. I have a black car that has really stubborn water spots. It’s been driving me crazy trying to get them off. I put a little of this in with a micro fiber cloth, wiped dry and finished with a spray on wax. In less than 10 minutes, Wow!!! So easy, no elbow grease needed. I’m amazed.

This product works well to help get the spots off of those difficult spots on my auto. In their information, they show this works on home shower glass as well, so I tried it there. Now this glass is aged and in not great shape....it did not help much. So if you are getting it for that reason only, I am not sure I would have given a 5

Struggled a bit with the heavier spotting. But did the trick and I liked how it came with pull cap and spray cap. Spent years meticulously maintaining paint and avoiding sprinklers. Just for my mechanics to park it under some hard water sprinklers covering my car. Glad this removed most of it.

I had read rave reviews about Adam's Polishes Water Spot Remover; but was very disappointed with outcome. I wish I had taken some pictures, but did not think about it at the time.I had hard water spots on the windows and left side panels from my overspray of water from my lawn sprinkler system. Plus, I had several coats of Rain-X glass water repellent.I used the Adam's Polishes Water Spot Remover as instructed on my windows. Although it removed a tiny bit of the hard water spots - I think it was more due to the elbow grease and washing off of the Spot remover that was the reason why some was removed.I ended up using Invisible Glass Glass Stripper and Water Spot Remover; which you could visually see the layers of Rain-X water repellent and water spots being removed from the glass as the product was worked into glass in circular motion.Thumbs down for Adam's Water Spot Remover.Thumbs up for Invisible Glass Glass Stripper and Water Spot Remover (which is only for glass, not car paint)

As long as you follow the instructions, water spots are no match. Got rid of all water spots on my new car and paint is as good as new again.

First, it does an excellent job at water spots on car windows. However, on shower glass where there are spots with soap scum, it does not work...at all! I tried different areas on the glass, I let it sit for different lengths of time, and used a lot of muscle wiping it off. Absolutely no difference at all! All of the spots were still there. I do recommend this for car windows, and I do not recommend it for shower glass.

The product works as it's supposed to as long as you follow the instructions. I had mineral spots on my car windows from water dripping in a parking lot. Sprayed the liquid onto a folded microfiber towel and worked it on the glass. Then washed with soapy water, rinsed and dried. The product must be removed after 30 second as it is an acid based chemical. If lefted on for too long, the chemical will etch into glass.

This stuff worked EXCEEDINGLY well for me on my 2022 Mercedes GLC 300 with black paint and really bad water spots. (We have hard water where I live.) Worked great on paint and glass. Just follow the instructions PRECISELY. I did about a 4 square-foot area at a time. I divided my hood into four sections. Work vigorously for 30 seconds then IMMEDIATELY neutralize with a water. The stuff is strong. Takes "some" Karate Kid elbow grease but not too bad at all.My recommendation is to go to one of those do-it-yourself carwashes that provide shade and soft water (most do). Wash and dry your vehicle like normal. After the wash, I applied the product generously to a dry microfiber cloth, worked the selected area vigrously using a cross-thatch pattern for about 30 seconds, then I immediately wiped the entire area with a water-drenched cloth, squeezing and wiping and and rewetting the cloth to make sure the product was neutralized and wiped away thouroughly.Don't use a wet rag to apply the product - the water will neutralize the product. Do not wet the surface first - again, the water will neutralize the product. As you buff it, it will form a slight glaze by the time 30 seconds is up. As long as your drench the spot with water and neutralize the product, you should be fine.I read one negative review somewhere saying it ruined their glass or something. I truly don't understand some people. Maybe that person tried to apply it to their entire vehicle and left sitting not just for 30 seconds, but a lot longer. I don't know. All I do know is this product worked for me as I precisely followed the directions. Go figure.
