It works a advertised. It does take some elbow grease to completely remove all the residue afterwards, but completely removes the hard water spots.

Was skeptical that it would work, but all doubts are gone! Worked great!

Used this on my stubborn rv shower glass doors. Water marks and spots were there for a few years. This product cleaned them right up and looks great!

Best thing I have ever used! As advertised get the impossible hard water stains off. I tried everything multiple different brands and methods. Nothing worked until this stuff.

I had tried everything to get the hard water spots off a truck I had just purchased and absolutely nothing worked. I spent hours trying and had just about gave up and was deciding to get a new windshield. I would highly recommend this product!!!

I am a professional detailer and I’m excited to try the other products they offer. I tried the glass water spot remover and liked it.

My 8 year old pickup lives outside. It has had water spots on the windows for years! I have tried every water spot removal technique and product that I could find including steel wool and rubbing compound. Nothing has worked and I thought they were going to be there permanently. Until I tried X2. I had to go over the glass a few times and with a good amount of pressure but finally success! My windows are now spot free. This is a great product and based on the results I am going to order the spot remover for the paint as well. At last my search is over! I highly recommend this product.

Amazing product!! I purchased this product hoping for great results in removing the water spots off my shower glass. I have tried more products than I care to admit. I kept seeing this product on my Facebook feed and thought about it and looked on YouTube for reviews and pondered over it and finally said okay! It took forever to arrive, but I waited patiently. I got a nice course sponge and first did the door……the result made me so happy……….the next day another section and then the last section………I have called my friends to share the amazing results…..I am glad I bought two bottles…….I find myself walking to the bathroom just to enjoy the results!

Love it best product I used so far

Awesome

Love the products.

I have some nice cars and storms here in NC have taken a toll on them. Especially my corvette..Hatd water from the struggles of purifying water here after the storms played havoc on it. Even after after hand drying and air blowing every drop off. Water spots! Gotta hate them. I tried everything! This was my last resort as it popped up on social media. I’m a skeptic when comes to it. It’s awesome! Will forever be a customer!

Full transparency, this purchase of Sud Factory’s water spot remover was an impulse buy from an ad on Instagram, and I have no regrets! My 2019 Mercedes E450 in Onyx Black had waterspots on the hood from the day I purchased the car. If I had to guess, these spots had been there for the past several years and were completely resistnat to hand washing. I finally decided to do something about it when I saw the Instagram ad for this product. As advertised, the spots were gone in a matter of seconds. It didn’t even take multiple treatments, which absolutely blew my mind. This stuff just WORKS!!! Awesome product!!!

I saw the ads for this product and was very skeptical. Have tried various methods to remove waterspouts for years. I used the products last night on my 22 year old truck and with minimal effort, glass looks new!

Fantastic product and extremel fast shipping!
