yes
I think you will find that the Ettore rubber is your problem, that is why you have to wipe your rubber between each pass of the squeegee. The Ettore rubber is narrower in places and causes the soap to come over the back and on to the glass while squeegeeing.
It is not a problem with all Ettore rubbers the bad ones come in large batches, and they are only fit for the bucket, unless you want to waste time wiping the rubber every time you take it off the glass.
I told them about it years ago but they were not interested, so I changed to a different brand.
Change to Pullex SOFT and you won't have to wipe your rubber no matter what soap you use, or how much soap. Pullex is much cheaper anyway, and is a much better rubber.
