GyeonWater Spot Remover for Paint Safe Use on Ceramic Coating Hard Water Stain Cleaner Mineral Deposit Dissolver Auto Detailing Chemical Protects Finish Enhances Gloss Easy Panel by Panel Application

Understand this; water spots are minerals that are etching their way slowly through your clear coat. This product like many others is going to use an acidic primary ingredient to dissolve the spots (which are minerals) With this I had to let it sit on my paint (cool area in the SHADE ONLY)I agitated it in with a cheap small thin microfiber. You want the entire treatment surface to look wet, as in it’s being coated with 100% surface saturation. If it looks like it’s beading up or clinging together in clusters; you have wax or another sealant preventing it from covering how it needs to. To solve this you need to either IPA wipe or use a paint prep solution to clean off your protectant before it will truly cover the surface and do its job.From that point you should be able to use your agitation microfiber and massage it into the area like lotion - light pressure! (It’s primarily a chemical means of removal, not physical.)You may need to do this 2 or 3 times depending on severity.Now here comes the problem people or even you may run into; those old water spots, if left untreated for a very long time, may have already literally eaten their way through your clear coat and made a permanent crater… even after minerals are removed your WILL still see this if this is the rare case!I just used this on my personal vehicle and it works very well. The photos I posted are the only ones I have a before and after of, but I had to treat my whole vehicle’s top surface.I am a professional detailer and run my own service company, this is a great product and I will continue to use & recommend it.

This crap does not work at all. I tried returning it but it wouldn't even allow it for some reason. I would like to return and get my money back. Chemical guys water spot remover is what I ended up with since it works much better than this crap.

Had some bad water spots that wouldn't go away. Easy to use and works good

removes hard water effectively....good product

Product works good, but bottle leaks and is broken

I've tried this product on paint and glass 3 or 4 times and it never removed a water spot. It's difficult finding products that actually work as stated. This is like many others. Ineffective.

This stuff works. Be careful and read the instructions, to avoid any paint scares.

I had high hopes for the Geon Hard Water Spot Remover, as I trusted the reviews and the brand's marketing. However, I was left disappointed with the product.Firstly, the delivery was delayed, and by the time I received the product, the water spots on my car had already been sitting for a while. I was unable to remove them as quickly as I had hoped.Secondly, the product only seemed to remove the lightest water spots that could have been taken care of during a regular car wash with a little bit of elbow grease. The more stubborn water spots were still present, even after using the Geon Hard Water Spot Remover.Overall, I was disappointed with the results of the product, and I feel like I could have achieved similar results with a regular car wash. I would not recommend this product to others looking for a solution to hard water spots on their car.
