nextzett 92100815 Kristall Klar Washer Fluid 1:200 Concentrate - 8.5 fl. oz., Green

I have been using Kristall Klar for YEARS. I originally found it during my search for a wiper fluid that did NOT leave some sort of water repellent behind.Pros:-This performs well and gets just about the nastiest stuff off of the glass even in the baking hot sun.-Might just be a placebo effect but it feels like I use less fluid per spray to get the windshield clean compared to normal washer fluid.-It always wipes and dries cleanly while leaving no residue behind to cause wiper chatter/skipping.-It's also strong enough to clean the rubber in your wiper blades without destroying them. People underestimate how dirty the blades themselves get which can also cause poor performance and noise. A typical car wash won't remove this type of dirt/contamination.-Ridiculously economical: 1 bottle will give you multiple GALLONS which should last you for many years.-Last but not least: AMAZING lemon-lime scentCon:The only downside is that this particular formulation isn't winter proof. BUT they do make a winter version (which I bought but haven't had a chance to use yet) and both versions can be mixed together.

Its very effective in clearing the windshield with far less needed over my previous OEM BMW solution. This solution goes on more sudsy, yet wipes clean via the wipers, airflow (moving vehicle ), and cloth when parked. Virtually no streaking despite clearing bug, road, and environmental debris. This was especially important to me as currently I am parking outside more often than not. Which leads me to my last, but important bit of praise. I bought this product because of its claim to recondion the wiper blames and keep them plaible with proper use. I was skeptical, but felt that even if untrue, it would still be an upgrade over others I have used. Imagine my delight that it has quieted my stiff and dirty blade installed last spring, but the seem to remain more like new with a continued use, which for me had been every 2-3 days of uses including parked in the direct summer/fall sun and SoCal smog/ash/dust/pollen. Im extremely happy with my purchase so far, and would highly recommend it to others! Actually have done so to several friends.

My only complaint is that it ships in a manner that makes it easy for it to spill, but otherwise, it's my go-to concentrate. Effective at cleaning and has a nice smell.

Cleans windshield well, smells nice, but kind of hard to measure. The instructions say 1 oz (the size of the measuring cup part of the bottle) per 1.5 gallons, which is kind of a weird volume. So if you use an old distilled water jug like I do, it's necessary to eyeball about 2/3 oz, which isn't ideal.

This stuff is amazing. Gets off the smearing winter grime.

I don't use a lot of washer fluid in our two cars and have had this for some time waiting to use up the old washer fluid. I was able to use the old gallon jug to mix this washer fluid in and did use a few sprays on the windshields. Amazing it cleans the windows. Is it better than windex or other products? I haven't used it enough to give an honest opinion. We live in the SE and it's getting to be bug / pollen season so the windshields will get dirty and I will add to the reservoirs for the wipers. It should do the job and I like the fact that it is super concentrated and doesn't take up much space in the cabinet, yet will make gallons of cleaner over time.

I bought this three years ago on a whim, and wow!! This stuff rocks! I always just assumed that the standard washer fluid you buy, whether the blue or the purple formula, was as good as you could expect. But after adding this concentrate (I add directly to the blue stuff you buy-- so I get the anti-freeze properties of the blue fluid), the cleaning performance became next level. The windshield gets cleaner, faster; bugs remove more easily, and the wipers even last longer. I used to have to change out my wipers every 6 months, maybe a year at most. Now I get 2 years out of them before they start to degrade.Highly recommended! And to be clear, I highly recommend you supplement blue or purple washer fluid... don't use it with water unless you're in an area that won't dip below freezing temps. This is not an anti-freeze formula, it's just a cleaning formula.Also, I bought my one and only bottle three years ago (Jan 2019) and it's still going strong. I use one metered volume per gallon of blue/purple fluid (you squeeze the bottle and it measures out the proper amount which you then pour off-- brilliant). I figure one bottle is good for 12 gallons. I only go through about 2 gallons per year. So the long term cost of this stuff is negligible. Worth every penny!

This concentration works well. In fact, it's much better than the fluid at the auto parts store for a fraction of the price. A bottle usually lasts me 2 years between 2 cars. Plus its just less plastic waste....Highlights:*If using in cold weather it still works, but can freeze when it's really cold or if leave the vehicle outside overnight. So, either get the winter version or add some alcohol to the mixture. I add alcohol because I only need it for about a month in the winter. It works and no problem.*If you are in North America, use tap water, there are hard water conditioners in the mixture and distilled water is not needed.*If you are cleaning your window a lot and it's not raining (bugs, dust), you may get a very thin soap-like residue on the car. It washes off easily, and no issues with the paint or wax applied. My windows are dirty all the time and I deep clean the paint and wax the car once a year with a synthetic wax. Again, no issues.*A hard note on experience; add water to your fluid reservoir or container first, then add the concentrate. Otherwise, it will foam up while you are adding water. Trust me on this one.Hope the comments are helpful.
