It is pretty expensive stuff, but you don't need to clean that much of the window surface really.
People sometimes worry about contaminants right at the edge between the window and the laser diode case, but there is no need. No light actually passes there, all of it typically goes through a small part in the middle of the window.
The main advantage of the polymer material is that it mechanically catches pieces of dust and such, and so is able to remove things that would not dissolve in isopropanol or similar solvents. It's not intended for, or good at, removing grease and and such.
For expensive diodes it could be a good precaution though, as dust will probably bake onto the window when the laser is turned on, and cannot be removed by any means short of removing the window afterwards.
