P & S Professional Detail Products Clarity Creme - Fast and Effective Glass Restorer, Removes Water Spots and Mineral Deposits, Prep Polish for Coating - 16 oz. Bottle

This stuff is incredible. Easy to use with a hex foam pad or mini polisher. Cleaned up water spots from my Tesla roof and windshield. I almost knocked it a star because as others have mentioned it came opened but it worked so well I can’t knock it.

I tried all of the other products and nothing worked on hard mineral deposits and water stains. Don't wast your money. Clarity Creme removed everything like magic whether applied by hand or machine. Product is not cheap but it works and you get what you pay for.

Used along with a drill polisher. Got 5 year old water spots off. Takes some patience but it WORKS.

Please try this, it works. This product is fantastic! I’ve tried so many products and this one worked. You can feel the build up being removed while rubbing the product on.

I've purchased this from their storefront for 3 years. Because of weather, decided to order from Amazon. Best window cleaner. So cleaner that it appears as if glass disappears. Recommend it highly. Their other products are great too.

product arrived damaged but was able to get a replacement no complaints amazing product.

Tried several times on some hard water spots and couldn’t tell anything different.

Unless you have “fresh” water spots on your glass , this will remove that. If you have hard water spots and been over a week or longer, it may not work at all. I applied this by hand and then used a polisher on a few different vehicles with water spots on the glass and it did not do anything. I would recommend mixing a cutting and polish compound on a pad to attempt to get harder water spots off. This product may only be good if your applying a ceramic coating on a new vehicle’s glass, as part of the prep.

Does the job, you must clean around your working area but is easy to clean.
