Rain Shield Windshield Washer Fluid Concentrate, 1 Bottle makes 32 Gallons– Repels Rain

I was skeptical at first, but it really works! I haven't used it in the winter yet, but so far during the summer it works great! Much cheaper per gallon than the Rain X we were using.

Just add the designated amount to a gallon jug - so much easier and less expensive than purchasing a large bottle that you go through quickly. One bottle has lasted more than a year despite using the solution frequently in the dry season to clear dust from my windshield (street parking).

Cant beat the price. Good product but a little watered down if you follow the instructions. I used a little more in my mix than the directions stated.

My family uses a lot of windshield washer fluid. We live on the coast in Florida and deal with love bug swarms twice per year. We used to store several gallons of washer fluid to ensure it was always on hand.This concentrate works equally as well as the premade gallons, it uses less shelf space in the garage, and is less than half the cost of Walmart's cheapest premade jug.

Water is just as good….Better off going to the dollar store and buying their cheapest glass cleaner and adding it to a gallon of water … Sorry I wasted money on this… Doubling the dosage didn’t make it better

Not too hard to measure and mix but if you get any of the concentrate on your skin or clothing it stains it blue.

I was skeptical but decided to give this stuff a try. It seems to work fairly good as a washer fluid. I started using during the summer months and didn’t think much of it. Yesterday, We had our first big rain storm of the season. I was amazed how well it worked as a water repellent. To me, it seems to work as well as Rain-X and you don’t need to apply it. The only downside that I have found so far is you have to use more product per gallon than recommended by the manufacturer. I doubled the amount to make it work effectively. I will definitely purchase again.

Great price, works well, small packaging and you add water means it's "greener" to ship and use compared to buying a gallon jug at a time, too. I was worried that a mere 1/4 oz would make 1 gallon of windshield washer fluid. But it works great -- cleaned off bugs, dirt, and tree sap quickly, dried quickly, left no streaks. For winter, I'm not sure I want to buy and add methanol to keep it from freezing. I may look into ethanol (denatured alcohol) instead. But at the least for warmer weather it is awesome.
