I used a small foam pad on my drill with this spotless glass. It took a few minutes to cover the entire passenger window on my car, but when I wiped off the haze, the spots were all gone. I live in Florida and the prior owner of the car let it set where the lawn sprinklers hit the car. The passenger side was covered in water spots. This stuff cleaned the glass right up.

I saw many advertisement on this stuff and decided to buy it over other products on the market. I'm a police officer in a rural area and we have some serious hard water, including terrible hard water spots on my patrol vehicle windows. I applied a small amount on my window and it worked over those hard water spots with ease, leaving a shiny and clear window surface. I'm a bit excited to have nice looking windows again! I'd buy this product again and recommend it to anyone with similar issues.

After trying several home remedies and store bought products. Using Sud Facrory Spotless glass and Dissolve paint water spots remover finally has our car looking as it should. The products were easy to apply and required minimal effort. I purchased the combo kit that included SFX I instant Gloss Coat Ceramic based coating. The car now has a mile deep shine. I applied the SPX to the aluminum wheels for the extra added shine.
I will be reccomending Sud Factory products to all my Car Club friends.

I'm a car guy who is constantly looking for products that actually work "as advertised". I've tried products from all the familiar car product companies most people are familiar with. Sud Factory products continue to impress me with their performance. Whether it's the water spot remover or omni- nano gloss coat, they work really well. Easy to use I've recommended Sud Factory products to all my car friends. Their products also work well around the home. The glass water spot killer is great for shower doors or stubborn water spots on exterior windows. I really appreciate their products, whenever I use them.

I have used multiple waxes and polishes over the years and this is by far the best and longest lasting!! Only stuff I use on my Corvette!

I left this on the website but I tried EVERYTHING I sent for your glass water spot remover and WOW!! Spots gone!!! I would stand behind this product 110%

Having purchased other water spot removal products in the past I was skeptical. Once I received my bottle I tested it out and it’s the best water spot product I have ever purchased. It takes very little effort and the results were amazing! Great product Sud Factory.

I had bough a water spot remover from “guys” it messed up my window horribly luck for me I only did a small spot. I had seen these before but was hesitant and decided to give it a try. LORD JESUS does it work 😂 took off every water spot from my window and chrome. I was amazed! You only need very little product and force. I tested it on a small spot and put too much force and scratched it a tiny bit. You only need very light pressure. Love the product!

This stuff rocks!! 🤩
Very little effort, great results!!! 😉💪

I used this stuff on my bathroom glass shower doors by the handle where it’s really hard to squeegee and IT WORKED!!!! I highly recommend and it was so easy and fast not a whole lot of effort to get it off either. I normally don’t post reviews because the products rarely are what they say they are but this, this is what it says it is. Here is my before and 1 minute later is my after. And it has a very light pleasant smell (reminds me of the bubble gum smell of big league chew) that didn’t hang around either.

I had tried everything from the vinegar and water mixture to another purchased product using both 0000 steal wool and a drill attached scrub pad. Nothing was making a dent on the shower doors. I saw this product on Facebook and figured I had nothing to lose. I was amazed that this product actually cut the water spots. Took a few passes with the drill scrub pads but it actually cut the water spots. I was AMAZED and extremely satisfied. Highly recommend.

I normally do not write reviews on products, but this one deserves a shout out. Original paint on my truck was so bad I considered repainting the truck. Thought I would give this a try and am completely blown away. Highly recommend water spot removal.

I’ve already told a few folks about it because the water spot removed some very hard water stains on my windshield and paint from soaked in stains from Washington’s frequent rain and then intense sunny days. I even told my Detailer about it who then placed an order to try it out.

Highly recommend!! If it could get these sun baked rain spots out I think it can get anything out.

Worked so good on my Harley I bought 2 more bottles of it. Absolutely a game changer for me.

I tried everything to get the hard water buildup off of my shower doors. Nothing worked. I saw the video of this being applied and wiped off, taking all of the water spots and build up off. I figured I would give it a shot since it looked so easy to use. I was amazed at how easily it took the build up off! It was so easy! Just wipe it on and wipe it off! I am a very satisfied customer.
