A Pricey but Effective Solution for Deep Cleaning Windows

Leonardo FuddyJuly 29, 2024

I was initially hesitant to spend a premium on Spotless X2, but I'm thrilled to report that it delivered exceptional results. I used it on my 19-year-old car, which had been sitting outside for its entire life and had developed severe water spots and grime buildup on the windows. The bottom edges of some windows were particularly affected, with a thick white film of mineral deposits. Before applying Spotless X2, I cleaned the windows with Invisible Glass to remove any large contaminants that might scratch the glass. While this helped, the cleaner still evaporated in a splotchy pattern, and the glass felt "grippy" to the touch. I then applied Spotless X2 using a dual-action polisher with a foam heavy cutting pad, working in vertical and horizontal passes to ensure even coverage and distribute fresh product to problem spots. After letting it dwell for a minute or two, I wiped it clean with Invisible Glass. It took several passes and fresh paper towels to completely remove the product, but the difference was immediately clear. The Invisible Glass cleaner now evaporated evenly, and the surface was no longer grippy. The mirror-like properties of fresh glass were restored, and the windows looked like new. The only areas that required extra attention were the bottom edges with significant mineral deposits. The dual-action polisher didn't quite finish the job, so I had to use some targeted treatment and elbow grease (or rather, finger grease) to remove the contamination. However, Spotless X2 still worked faster than I expected, and I was amazed at the results. Despite the higher price point, I'm convinced that Spotless X2 is worth the investment. It's a wonderful product that delivers exceptional results, and I'd happily choose it again for deep cleaning windows. Read more

Worth the money

JeffDecember 31, 2025

Very good product. It removes water spots with little effort. It's the best product for removing water spots that I've come across so far Read more

Worked well, but you better stock up on elbow grease!

Mark TurnerMay 7, 2025

This stuff did remove the hard water stains from a shower door. The parts that were minimally stained came clear with just a few seconds of work. The parts that were severely stained would not come clean after repeated attempts. I finally broke down and used a drill mounted polish pad and really worked the area over and the severe spots came clear as well! Other than the fresh and minty smell, I'm not sure this product is much different that any other polishing compound, so if you have any of that around, maybe give that a try first. Pro tip: shake bottle before use! Read more

It works fantastic and will last forever!

NormNovember 12, 2025

This stuff is fantastic! Merely use a couple fingers to apply to glass in a swirling motion over a 6-12” square area and just wipe off with a micro cloth! Spotless windows! In my case we have super hard water and spots “galore” due to our sprinkler system is always catching a window! My son let me try his and I immediately ordered my own!!!! Read more

Save your money!

Renee LiuNovember 3, 2024

The product shows the ease of removing water stains by using little to know force just putting the product on the surface. Via the Instagram videos I seen. I used two coats of this stuff on my surface and it barely does a thing. I let the product sit for a few minutes and to be sure it was going to be effective I also applied force using a micro fiber towel. This product is just as good as any of the other water spot removers I used over the years. 👎🏽 Still stuck with those water spots. Keep in mind that I also compound and polish to break down my water spots so there wasn’t that much build up on my windows when I applied this product. Save your money and get yourself a good running compound, polish and a buffer. On their official website they have an original price of $70 per bottle. But it was “on sale” for $35. I should’ve seen that was the first red flag. No company needs to over compensate by pricing their product as expensive and faking a discount to make sales if their product was actually good. On Amazon their product price is consistently $35. Read more

Finally something that actually works!

BrianSeptember 3, 2025

I have a well, and my windows were completely covered in hard water spots from the sprinklers. I had tried multiple products and all the usual home remedies with little to no success. Nothing seemed to cut through the stubborn buildup—until I tried Sud Factory Spotless X2. This stuff is the real deal. It worked amazingly well and didn’t require a ton of scrubbing or elbow grease. After using it, my windows are crystal clear again—it honestly looks like they’re brand new. I couldn’t be happier with the results. If you’re struggling with hard water stains on glass, don’t waste your time like I did with other cleaners. This product actually delivers! Read more

Omg!!! This works!

mmollatDecember 14, 2025

The media could not be loaded. I tried everything. And I mean everything and I couldn’t get the water spots out on my used car. I was almost considering getting new side mirrors. But I thought I’d give this Sud Factory spotless water spots remover. And boy I’m glad I did. Read more

Takes some elbow grease

JGDecember 17, 2024

A little disappointed. The videos show very little effort being made with great results. Rest assured if you have water spots that have been established any amount of time it will require a good amount of effort and multiple applications to remove. I would say 7 out of 10. Three stars is a little low. My other go-to product is Mad Acid. I would say this product has a slight edge over mad acid due to its less caustic and easier to use. Either way make sure you glove up.
