That's exactly what I do, never use a de-mister pad either to keep it streak free, just sit and wait for the blowers to clear it...people must think I'm mad sat there for ages some times??
Maybe we should all buy fords or Renaults and get the heated windscreen...no need to ever get it smeary when it mists up a little! ...Then again.....fat chance of doing that, would rather spend hours cleaning and waiting for the blowers to do the job.
