P21S11250F Booster Measure Bottle, 250 ml

Brilliant product.

You certainly don't *need* this product. But you're here looking at it, maybe wondering if it's worthwhile. It's absolutely worth it.Mixed into the tank with regular washer fluid, it results in a more sudsy solution that better sticks to my windshield and gets the window cleaner, faster. Previously the washer fluid had a consistency like water and would very quickly bead off the windshield, requiring a lot to get my window cleaned. This is like adding a little bit of soap in that it's a little sudsy, allowing it to cling to your windshield and dirt better, but still be easily removed by the wiper blades. If you're a fanatic for having a clean windshield, this stuff is fantastic.Also, a little bit goes a long way. The bottle is a little pricey, but it's lasted me forever.

I initially discovered this product on the German economy while living there for several years. Upon my return to the USA, I couldn't find it. I've owned various cars in my lifetime but this product actually does a hell of lot better cleaning than any brand out there. Since I live in a warm climate, I always use distilled water (to prevent white mineral deposits on the window spray nozzles). Simply add this to the window wash reservoir, add the distilled water or other cleaner you trust and wait 24 hours. The ability of the cleaner to produce a more streak free cleaning has always amazed me. Clarity is the one word that describes what this additive will do for your car. One bottle can last over a year!

Works exactly as described. Leaves windshield clean and clear of streaks. Must have screen wash additive.

This does indeed boost the cleaning power of cheapo blue fluid and even better helps create a much more streak-free window when it dries in the wind over the blue stuff alone. I have yet to see how this might work when paired with distilled water in the summer. Scent is there but doesn't bother me. Its a bit citrus, so its kinda down to preference if you like it or not. The bottle was easy enough to use to measure the needed amount.However its not quite the catch all. It still can't quite manage to clear bugs, though it can reduce the splatter when used.

I am a regular guy who likes to have an “edge” on everything...I say This because reviews these days seem to not be legit. Anyway I use this along with Prestone orange three season or three in one washer fluid. I did 2 “squeeze” amounts per gallon and I am a true believer. I might’ve used to much because you can Actually see “suds “when I clean the windshield. So I am a true believer in this stuff, I’m going to try a different brand that looks similar and see how it does because it appears to be five dollars less

great for seeing clear windshield, no streaks

Good as alwsys but when squeezing it up into the bulb it foams like crazy. Never did that before. Wonder if they changed the formulation a little.
