The Clear Glass formulation provides a streak free finish and cleans glass using the 2 towel method. The trigger spray only allows for a wide spray rather than the option of a wide spray or a more accurate narrow spray, but for this application the wide spray is more than suitable. For smaller windows only one wide spray was required, but on larger windows two to three sprays was required. The solution is not too volatile so that there is no time to work with the product, after the product hits the surface there’s ample time to work in the product and then buff off the solution with the second towel, to leave a streak free finish.
Worth a purchase? Possibly, could probably get an equally good product for less, but a strong product nonetheless.
