This product it is just amazing. I’m not uploading pictures or anything because I didn’t thought it was going to work that good. I had some really bad water spots in my car, in the driver’s side. All the way. I tried with many different products and none of them seemed to work till I got this one. I applied directly to the affected area and the magic started. I didn’t have to scrub hard or anything similar. I finished up covering the whole drivers side area and once I rinsed it. Brand new. I wan...

This stuff kicks ass. I’m a meticulous person, so when I saw some water spotting on my PPF’d, coated Porsche I was caught off guard at how I let it happen. Didn’t need to worry about that. This made quick work of all of it with about 5-7 seconds of dwell time. PPF safe, ceramic coating safe. Just be careful with it!

I have always loved this product for its ability to remove stubborn mineral spots on paint. I didnt know the formula changed. The old version was a 5 star product. The new version works ok, but the old version is much easier to work with in my opinion.

Love this water spot remover! This has hands down been the most effective water spot remover I've used. Great on windows, paint and wheels.

I had some bad waterspots on the hood of my 2024 vehicle that I thought I had let sit too long. I dug around on reddit and saw several recommendations for this product and thought I would try it out. I live in Hawaii and was very impressed that the package arrived the day after I ordered it. I did a test spot that evening with a 1:1 dilution and like a miracle, the water spots came right off. Treated the whole hood and it looks like new again. Im not that heavy into detailing but i am defin...

This stuff is amazing! At full strength it was able to remove set in water spots that no other product I have tried could. Highly recommend it.

The water spot remover worked amazing. All the elbow grease I've used previous and other products never worked. This product removed the spots without hesitation and very little effort. This will be my go to product from here on out for vehicles. I will also use this product on my glass shower doors for water spots and my windows on my house. Out here in Arizona water spots bake onto the windows with the heat out here. I can say 100% this product is added to my cleaning cart and has multiple cat...

Avoid like the plague if you are trying to remove water spotting from glossy black window trim (e.g., Tesla Model S). Used in a small test spot on the rear corner and it turned it into a cloudy white mess.

Years later and still my favorite water spot remover. Also excellent for cleaning wheels (that are ok to use acid on) and removing stains from paint.

Not the best water spot remover but for the price it’s okay

Buddy recommended me this product in hopes to get rid of some bad water spots on my Skeeter ZXR bass boat. I live in San Diego and fish in hard water constantly. I had already tried vinegar/water and had little hopes it would work. This was my last ditch effort before paying for a full polish from a detailer. It was easy to apply and required little effort. Will always have a bottle of this in the garage from now on!

The only Spot Remover I use for water spots. Glad I found this product! It turns hours of work in two minutes.

I used it on a glass shower door and it worked instantly removing spots that ordinary glass cleaner would not touch. I have not tested the new formula at this time.

Best water spot remover on the market I have cleaned hundreds with it with impeccable results and no other competes. -J.P.

My glasses are cloudy from dishwashing. I was hoping this would work but it didn’t .

UndrDog Spot Remover is the best! I highly recommend it.

Well, I first had tried another top name product that worked good for water beading but it did not remove the water spots. I tried UndrDog WSP product add this product worked excellent. The spots were gone and a nice shiny surfacing again on my SUV. I have already re-ordered more of this product. I highly recommend it for an absolutely nice finish!
