Boat Bling HS-0128 Hot Sauce Hard Water Spot Remover, Gallon Refill, for Boats, RVs, Powersport Vehicles and More, Black,1 Gallon

Used this on my boat that had some pretty stubborn water spots even after always wiping it off with either ONR or straight vinegar after every use. This definitely got rid of most the water spots but for those really stubborn ones, that will take a little more elbow grease and some machine polishing, this product won’t do that trick. Definitely worth having and using every trip to reduce/prevent water spots and it also offers some added protection.Like others said, it doesn’t have a particularly good smell, smells a lot like vinegar but that’s okay by me.

I don’t write a lot of reviews, but compelled to write one for this Hot Sauce because it worked so darn well. I had water spots on my jet skis that I couldn’t get off, even with some light rubbing with a magic eraser.Bought the Hot Sauce and was cautiously optimistic. Immediately after washing, blowing off with leaf blower, and chamois dry, I applied the Hot Sauce and dispersed with damp chamois. Then wiped off with dry chamois. Bingo, water spots are gone. Didn’t have to rub, just wipe and dry….super easy.My skis look brand new and I couldn’t be happier. I like my sh….tuff looking good and Hot Sauce helped me get there. Skis were left with a babies butt smooth finish as a bonus. Awesome product!

Works great on my Lund boat.

After reading negative reviews I almost didn't push the order now button, but I'm sure happy that I did! The various minerals in our water out here in Idaho Falls are relentless. Hard water spots out here are just accepted, it doesn't matter what gets wet. The water coming out of my spigot is over 300 ppm, I have not measured rain water ppm, but I know it's much worse just by comparing the looks of the water spots from both mentioned sources. I usually use the DI-120 de- ionizer from Spotless, but my resin cartridge had run it's course. So I washed my brand new 2025 Chevy Silverado and dried it as best as I could, the result could have been better. So I ordered the hot sauce and poured some in a small misting spray bottle to take care of some stray spots. Within seconds, after following the instructions, these heavy water spots were gone, with no effort at all! It did not damage the paint on my truck, or leave any streaks! I highly recommend Hot Sauce, I do suggest that you know what your up against by measuring how hard your water really is, mine was a bit higher than 300 ppm, but I felt there was still more strength in the Hot Sauce to tackle even higher ppm. I don't know the max it will handle though. For 20 bucks is way worth trying it out to me.

Product seems to work really well and has got all water spots off my stratos very nicely. Just a simple spray and wipe seems to go along way, the only reason I give it 4 stars and not 5 is because I expected it to have a better scent to it but the scent is not desirable at all, not really a big deal just not exactly what I was expecting I guess. Id still buy this product again and continue to use it though!

With a car's many materials and surfaces, the old saying is still the truth: "The best cleaner around, is to motivate yourself never to let it get very dirty in the first place" THAT's the best cleaner!So, if you don't follow that motivation, the marks you allowed to stay on the surface the longest are the marks that take the longest to completely remove. NO product gentle enough to use on your gear will be powerful enough to erase long-term residue in one treatment. Not even this stuff, so let's get rid of that kind of hope and optimism."Water Spots" is a wrong term we always use. It's not the water that stains your glass and paint at all--it's the minerals/salts/calcium that bind with dirt and form tiny circular crust on your surface.But be warned, "Hot Sauce" is the right term for this agent, because near your nose it's got a kick to it that reminds you of really spicy stuff your friends splash on their food for heat. Not foul smelling, but a "dragon pepper" vapor that will clean the sinuses of your unborn grandkids. So wash you hands thoroughly after using this stuff.The calcium spots on my car glass are anywhere from a month young to a wretched four years old. Mineral spots don't just form cute dots when they dry, they form vertical river-lines down your door glass, that you only notice when you windex your glass, and they leave an invisible "craze" pattern on the front windscreen that only appears in humid rain or when you're trying to defog the glass in winter time---it can endanger your driving.If you have these issues on your car glass, this is the true product to remove it, completely. But like some owners will never realize, the older you've left a stain on your car, the longer it will take to finally work that stain off.Hot Sauce quickly removes spots that are less than a month old--gone, baby, easy! You can use a paper towel to spread the juice all around the glass, but I strongly suggest a genuine microfiber towel to wipe it away afterward. You only have to wipe, no need to rub, which is good--this is laminated and plate glass for goodness sake--you don't want to be dragging scratches into it. After two minutes, you wipe with the micro-towel, and the glass is smooth like you used a clay bar on it. If water or rain hits afterward, it beads up so wildly you hardly need to use your wipers to see as you drive. Even Rain-X products don't bead this tiny and bright.It seems to work fastest and best on the door mirrors (they are just treated plate glass). Spray it on dry glass, and all spots wipe away after two minutes.It works almost as quickly and well on front/rear windscreens (remember, on a car these are laminated glass with a different skin than your door mirrors or boat owners' panels). I applied it when the windscreens were very wet, gently spread it around the glass, and let it sit for nearly 20 minutes. Wiping it off is where the microfiber towel becomes really great to use. Under a microscope calcium and mineral scum is like jagged coral. AS you gently wipe with a true microfiber cloth you'll feel it snagging on the water spots. Repeat the application over a couple of days, and the smoother the dragging becomes. Yes, it took repeated sessions--more and more of the two year old spots clearly are gone.The door windows are the most difficult--those river lines are hard to see on sunny days, so you can only tell from the super smooth feel of the glass that you working your way down to the native glass you had when you first bought the car. It's satisfying to see and feel the oldest of the spots finally start fading out, and I've only done five repeated applications.Undo four years of scum in just a few sessions of casual wiping on sporadic days. And NO elbow grease to risk scratching my precious glass. Zero elbow grease + patience + million beads when it rains = A+++ product.

I was skeptical about the product, especially with the negative reviews. I’d put off washing my boat after each trip, thats because I fish a lot, but it took all the water spots from years of neglect, off my fiberglass boat -very little effort. Water rinsed the hull, applied Sauce in 2 foot sections, let dry for a minute, wiped off with microfiber cloth. Applied a second coat and a little elbow grease. Amazed.! Saved me from getting the buffing wheel out.

The best thing to use in between car washes.
