I previously made a video showing how to remove water spots from glass by polishing. No doubt, this approach works and is almost surefire but depending on the condition of the water spots, how baked on they are, and how much glass you have to polish, the entire process can take hours to complete.
Well, I’ve been experimenting and have found some products that are extremely effective in removing water spots from glass. These products are the offerings from Bar Keeper’s Friend.
This company makes many different variations of this product but I personally only have experience with MORE and Soft Cleanser. MORE is a more watery substance that sprays out as a foam whereas Soft Cleaner, although still a liquid, is just thicker. In terms of consistency, the closest thing that I can compare Soft Cleanser to is ranch dressing.
For a demonstration of the products in use, watch the video above.
To use these products, all we do is apply the product onto the glass or onto an applicator and just scrub them in. Now, it is extremely important that you DO NOT let this stuff stay on the glass for too long. The directions specifically say no more than a minute but it really depends on the atmospheric conditions. You just don’t want this stuff to dry on any surfaces. Bar Keeper’s Friend is essentially an acid and it removes the water spots by eating away the minerals that cause the water spots. However, if left on for too long, Bar Keeper’s Friend can etch the glass and you’re going to be worse off than just having water spots. But don’t worry, this sounds a lot scarier than it is. All you have to do is use something to neutralize the product. This can be as simple as just spraying the surface down with water, wash it with some soap and water, or use a waterless wash. In short, just use some sort of liquid.
In saying that though, keep in mind how water spots occur. In general, there are minerals in water. If you don’t properly dry a surface after getting it wet, as the water air dries, the water may disappear but the minerals are left behind and those minerals are the cause of water spots. So, if you get rid of the water spots with Bar Keeper’s Friend but you rinse with tap water and don’t properly dry, you’re just going to introduce new water spots and this is all going to be a futile effort. If you’re doing this, make sure to properly towel dry or use a car dryer like I’m doing in the video above.
If you’re interested in any of the products discussed in this post, look below where I’ve linked everything.
And that’s pretty much it. Apply Bar Keeper’s Friend to the glass, rub it in for one minute, rinse off and dry. The process can’t be easier.
From my experience, most water spots can be eliminated in just one application. Some of the most stubborn water spots will leave traces of their edges behind but that’s no problem. I can just do another application and that’s what I would suggest for you guys to do. If you’re worried about Bar Keeper’s Friend possibly doing some damage, play it safe and leave it on for noticeably less than a minute. Say, 30 seconds. So you may have to do a few more applications but this is definitely one of those better safe than sorry situations. And at the end of the day, more applications of this process is likely still going to save you a lot more time than some of the alternatives so no big deal.
Again, I only have experience with MORE and Soft Cleanser. Both of which you can see me use in the video above. However from my experience, one clearly outperforms the other. If you are purely looking to remove water spots from glass and not some of the other materials that these products are recommended for, Soft Cleanser is the way to go. Between the two products, there are some minor differences in the ingredients and that seems to make Soft Cleanser much more effective at removing water spots. Don’t get me wrong, MORE definitely works but where Soft Cleanser only requires one application, it may take MORE two or threes applications. Keep that in mind.
Either way, using Bar Keeper’s Friend is just so much faster and more effective than any other water spot removal methods that I’ve tried. But because there is some chance that this product can cause damage to your car, I can’t say outright for you to follow my lead. Do your own research and decide if you want to give these products a try. I’ll just finish off by saying this. I personally have used this product to clean the glass of my Supra. This is my baby so if I’m willing to use Bar Keeper’s Friend on it, then that shows the confidence and trust that I have for these products. I will personally continue to use them when water spots develop on the glass of my cars and I probably will never try anything else again. Bar Keeper’s Friend is just that good to me.
