Worth the money!
I have used this product for decades. This bottle was a replacement for an older one that was almost used up. Adding it makes the washer fluid clean much better so using less fluid probably balances out the higher cost of using a wash booster instead of straight fluid. I hope they never stop making it as I consider it an essential product. Easy to use, just squeeze until the small chamber is full and pour it into a gallon of fluid. I mark the jugs so I know I have added it.

Great Product Packaging BAD!
Great product, I have used for years in our Audi’s. However, the bottle dispenser is HORRIBLE. Now the first thing I do is cut the top off, then filter into a (recycled) pour style bottle. I just measure with an old fluid oz measuring cup. You will love the product.

Thsi stuff really does work!
I ordered P21S after reading an article about how well it worked on BMW windshields after they get pitted over time and dirt settles in the pits and makes it difficult to see. We don't have a BMW, but I decided it was worth a try but was not really expecting it to do much. The article stated the ingredients in P21S are used routinely in European windshield washer fluid but not in the US. My husband does not see well at night to drive, and no windshield washer fluid seemed to help with the film on the windshield. We cleaned our windshields with Bon Ami, which worked well, but every time we went through the car wash the same film came back on the windshield. Now we add P21S to every gallon of windshield washer we buy and cannot believe the difference it has made with cutting the film off the windshield. It really works and cleans the film off almost instantly! One bottle will last to be added to16 gallons of windshield washer fluid, so it is not that costly at all.

Not sure if it is really helping
I am not sure if this product really helps. I bought this expecting it to help remove bugs from the windshield, but does not really help.

I've used it for years. Adds a detergent to your normal windshield washer fluid, giving it better cleaning ability.
