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

I am beyond impressed with this product quality and effectiveness! I had hard water stains on my car from the neighbors sprinkler hitting it constantly. I tried about 5 products before this one and they wouldn’t budge! One application of this and a light scrub with a magic eraser — BOOOM, water spots be gone! I will be buying the whole line of products to protect our cars going forward!Thank you product engineers and R&D teams, it’s nice to have a product live up to its claims for once! I added some before and after photos for integrity!

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.

What an amazing product! It does have the smell of vinegar but it works exactly as it should. Bottle is very durable and no leaks during shipping. Great value for the money on this refill. Great product that does it exactly as described and I have no complaints at all

Amazing stuff! It made my painted aluminum boat look like brand new, and it even took ALL of the old white gunk off my lower unit.

Make sure and wet surface first before applying product for better results. It removed the majority of the water spots quite easily. Would recommend this product.

I have used many different boat cleaning sprays and by far this one is the best! It cleans all the water spots and does NOT leave any streaking (as many of the other ones do).Very easy to spray on and wipe off. The smell is great and you can tell it will work when the wind accidentally blows it in your eyes and they sting a little.

I love telling people to use hot sauce to clean their car, ha! This stuff removes water spots from surfaces better than anything else. It's not a gimmick like many other car care chemicals, it really works and is easy to use. Just spray on and wipe off like any other speed wax or detail spray. It's quite durable, too as it maintains it's slick surface for weeks after application.The only downside is it smells like vinegar. You'll get over that after you see the shine. I'd also consider it safe as vinegar isn't too harsh of a chemical.

Works on the car paint but did not work on windows. Good enough.
