Meguiar's Water Spot Remover, Water Stain Remover and Polish,16 Oz

I have upgraded my review of this product after trying two other options: 1. BioClean 2. Meguire's Ultimate Compound I knew BioClean would be too harsh and it is. For removing water spots, it actually works very well in conjunction with Meguire's Ultimate Compound except for one major problem: it is very abrasive and damaging to plastic or paint, even the acrylic urethane finish on cars. The instructions say not to use on shiny car paint and that is an understatement. It will create fine swirl marks on paint and will haze plastic components like bumpers and sideskirts. BioClean is mean't to be used on glass or household applications like shower rooms. Obviously, what would you prefer: no water spots, or swirl marks on your pristine car finish??? The swirl marks are not as bad as waxing a dirty car, but you can still see it if you look closely. I knew the Ultimate Compound from Meguire's would be a stop down from their Water Spot Remover product since it is basically a compound and it is. It has finer grit in it and is not as effective at removing water spots. Works very well though, if you apply it after BioClean. I found the Meguire's Compound Water Spot Remover will not completely remove stubborn water spots, but at least it won't damage automotive finishes. It also buffs out to a nice waxy shine, much better than the Ultimate Compound. What I do now is apply this product a couple of times. Each time it removes more and more of the water spots. I call it a day after that, knowing any other options may damage the finish on the car, or be less effective. Because this product is a compound, it does remove some paint since my car is Race Red and it leaves the white terry cloth I am using pink in areas if I rub too hard. I then finish up with my wax of choice: 3M Performance Finish. I mainly needed to remove bad waterspotting under the hood and trunk lid, on top the fenders inside the engine compartment and the drainage trough underneath the trunk lid. I had the car in storage and the storage company washed the car a couple of times, but did not wipe off water spots in those areas. This product will remove spots fairly well on areas that were waxed, but on unwaxed areas, the spots still won't come off completely even with multiple applications and hard rubbing. Fortunately, I don't have to use this product on the outside top coat since the storage company dried that out OK after a wash so there are no water spots. BTW, if you want to remove water spots on flat glass, it's easy. Just use a sharp razor blade, works like a charm! Turns all those deposits to white dust. Just blow it off the glass or clean it up with window cleaner. **Wink** Won't work on paint though, as the razor blade might dig in and scrape the paint.

This worked really well on my black painted truck to remove water spots. Highly recommended.

I had hard water spots all over from getting hit with a daily sprinkler. My car was parked in the same spot for just under a month and sitting in the hot sun so the spots were pretty well baked on. This spot remover ultimately worked, but it wasn't easy. It took several applications on a few different days until I could finally remove all the visible spots, and that was with heavy scrubbing using various microfiber cloths. At first I was using a wet cloth to prep the vehicle and wipe away the product but I found out that it actually seems to work better without any water, when the car is completely dry. I had the best result when I applied the product directly on a dry surface and scrubbed continuously, then used another dry cloth to wipe it away when I was finished. Thankfully it did work in the end but I did not anticipate it being as difficult as it was to remove relatively fresh spots so I'll give this 4/5 stars for ease of use. Thankful my paint isn't damaged though!

This stuff works great! Works instantly right when you apply it on to the affected area. I wish i had an after pic but it started raining right after i was done buffing :/ but I’ll definitely post it when it’s sunny again. But definitely recommend getting this product! I will be buying another bottle of this!

Meguiar's Water Spot Remover is a decent product that delivers mixed results. I bought this to help remove water spots from my car’s exterior, and while it did work to some extent, it didn’t completely meet my expectations. The application process is straightforward. The product is easy to apply with a microfiber cloth, and it doesn’t leave behind any residue. It worked well on light water spots, particularly on the glass and paint surfaces, giving them a nice, clean shine. However, when it came to more stubborn or older water spots, the remover struggled. Even after multiple applications and a bit of elbow grease, the toughest spots remained visible. I also noticed that on darker paint, it sometimes left a slight haze that needed additional polishing to remove. Overall, Meguiar’s Water Spot Remover is an okay product for maintaining a clean look and addressing minor spots, but it may not be strong enough for more severe water stains. It’s worth a try if your water spots are relatively fresh, but for heavy-duty cleaning, you might need something a bit more powerful.

Two photos shown: passenger’s side window before using the product with vertical streaks of hard water stains, and driver’s side window after using the product. Mr. Clean magic eraser didn’t work, glass cleaner didn’t work, this product worked instantly.

Very disappointing. I used to love Meguiar’s! Their old spray formula worked beautifully on my car years ago. This product unfortunately did not work at all to get the hard water spots (from our sprinklers) off. Tried repeating several times, but none of the spots came off. Do not recommend.

AMAZING PRODUCT FOR GEL COAT WATER SPOTS!! We have a dark colored surf boat and the water spots make me INSANE. Before we launch this year I wanted the boat fully detailed, but couldn’t get the weather to cooperate for a pro to come do it. So I went at it with this stuff. Holy moly, amazing. Even our windshield looks AMAZING, and it gets water spots so bad. I used Jescar over it all and it’s ready to rock. HIGHLY recommend this product. We use hot sauce in between and it’s okay, but wanted something a little more serious, this is it!! I could see myself in our boat even before using the Jescar. SUPER IMPRESSIVE.

This product did a great job removing water spots. I used it twice on some tough stains, and the results were excellent. It was gentle on the paint and did not damage the car's finish or polish.

Works perfectly in removing water spots and shining

It does what it is intended to do, remove water spots from car surfaces.

La verdad es que yo casi nunca soy de dejar opiniones sobre productos, pero este definitivamente se lo merece por su excelente desempeño y los formidables resultados que ofrece. Desde la primera aplicación noté la diferencia. Es sumamente fácil de usar, no requiere complicaciones ni procesos largos. Con muy poco producto y siguiendo las instrucciones, las manchas desaparecen prácticamente al instante. Lo que más me sorprendió es que quitó las manchas tanto en cristales como en la pintura a la primera. Tenía marcas de agua bastante visibles que ya había intentado remover con otros productos sin éxito, y este las eliminó sin problema. Funciona de maravilla y deja la superficie con un acabado limpio y brillante. Sin duda, lo recomiendo ampliamente. Es de esos productos que realmente cumplen lo que prometen y superan expectativas. ¡Totalmente satisfecho con la compra! 🚗✨

Excelente producto , cumple muy bien en vidrios y carrocería es muy fácil usarlo
