Originally purchased the product for hard water stains on my boat windows. I have tried the chemical guys and vinegar and water without success. Decided to do a test on my shower door. My shower door is horrible w hard water. Sud factory did Amazing. Due to the severity of the hard water stains I did use a drill and scrub pad attachment. Highly recommend this product

This product is a 10/10.Removes water spots as advertised.No harsh odor.Haven’t witnessed any scratches or scuffs to me vehicle windows.Not sure of durability because I applied it 2 days ago but it does remove spots.The pictures are the same spot on my sun roof 3 minutes apart with some elbow grease.Took me roughly 30 minutes by hand to do my whole sun roof.

I've seen ads and posts for this product line for months before I thought to try it. I already had a water spot remover product, but it was more like a gel, and was a pain to apply. I was wanting to do more auto glass services, so I needed a good water spot remover. I thought to give this a try. I'm kicking myself for not having done it earlier! This product is amazing and well worth the price. Here's the cool part. There were a couple situations where I needed to get water spots or hard water dirt areas off of paint. I thought to try this on the paint. It worked great! Maybe this and the paint water spot product share the same chemistry. I own an auto detailing company in Oregon called Awesome Headlights (https://awesomeheadlights.com), and these products will be invaluable in getting tough work done quickly. Order the product and you'll thank me later.

Neighbors sprinkler had beat the **** out of my truck and I being a dummy left it sit for months. I tried several products including Chemical Guys Water spot remover (I like their products so no dig) but this stuff is the only one I’ve found to work.

It works…. But not anywhere near as easily as they show in the advertisements.The amount of force you need to apply to the window is almost everything I have.If you’re not pushing at least 80 lbs of pressure, it’s not going to work.Wish it was easier.

I’ve tried several cleaners, Magic Erasers, polishing compound and solvents to get rid of the water spots on my Acadia sunroofs, and none have worked. Sud Factory does work. I was unable to get a better picture, but the roof closer was treated, the rest what it looked like before treatment. It took a little elbow-grease but nothing excessive, and not much product.

Great product could not be happier! Water Spots removed from glass. Easy to use and works great!

I bought this thinking it was another gimmick but dang! My windows were so bad and this literally melts water spots! I’ve used buffing wheels on drills, top name brand stuff and none of them work as effortlessly as this. I did a frontier 4 dr in less than 2 hrs. I even ran over the bottle and it didn’t explode. I’ve sent this to my friends and family. I kept saying wow every time I finished a window lol. I can’t wait to do my Sierra and Camaro. Nothing like brand new looking glass!

My mother’s car had 6 years of water-spots ALL Over her car and windows. I purchased the Ultimate water-spot remover and protection kit. Let me tell you…THIS STUFF WORKS! After 2 rounds of working it into the paint and windows her car LOOKS BRAND NEW. I even shined my strong flashlight on her car at night for a true test and the paint is free of water-spots. I am really amazed how these products worked. Im NOW a lifelong customer and will definitely be referring my friends and family to these products. THE GLOSS COAT in this bundle adds the protection I was looking for to prevent any future spots. Car looks like a 2025 right out of the showroom. Thank you for making products THAT ACTUALLY do WHAT THEY CLAIM to do!

Works perfect on removing tough water spots from the paint.
Really satisfying with this product 👍🏻👍🏻
