Yes, the chattering is caused from the alchaol from the Rain-X comming in contact with the wipers. This is why I apply Rain-X prior to washing my vehicles with the wipers in the up position.
I apply the R-X, then for example, vacuum the interior/clean the interior windows or wash the wheels/tires/undercarrage. Anything to allow the R-X to at least dry to it's smudgey look! Aprox. 30 minutes...Or longer!
Then, and only then do I wash the whole vehicle as normal but, always keeping the wipers in the up position. Once the vehicle is washed/dried, then let down the wipers onto the glass.
This is one of my FREE detailing tips that I offer to the members of BITOG. I have posted other FREE tips but, inconspicuously; I just kinda threw'em in there!
