I shudder at paying premium price for cleaning rubber and glass. I use vinegar, Dawn
detergent and water...with a light touch and a 3m pad for the glass. Periodically, I also
pull out the steam vapor machine to clean the glass. I use silicone dressing from a $5
can on wiper blade which has lasted 10 years now. Anecdotal, of course, but I'm still
on the same Bosch wiper I've had since about 2010. I park the car indoors so it isn't
subject to a lot of environmental cooties 24 hrs. I'm not working now so I need to
mix my own stuff when I can.
