Window cleaner concentrate

Good concentrate, makes lots of cleaner and works well.

This product goes a long way. I used it along with the Karcher power squeegee and had amazing results.

it cleans great and the smell is fresh .

Very good glass cleaning solution! Best I have used.

Works perfect without stripes

Works great, thanks.

If you are going to spend the money for Karcher's expensive detergent, don't buy it in this format! Look closely: this supplies only four 20-ml packets, each sufficient for only one fill of Karcher's tiny 8 oz spray bottle. You can get the same product elsewhere on Amazon in a 500 ml bottle for $25, 1/3 the price per ml. All of which begs the question as to whether Karcher's detergent (they like to use the term "surfactant," a pricey word that means "detergent") is really a better product than others you can buy for far less money. I use my window vac primarily to clean slate kitchen counters, & I do find Karcher's cleaning solution works better than Windex. I'm eager to hear from other customers who have compared other products.

Great window cleaner solution.
