Windscreen wipers - How to improve??

I use that Mer Windscreen cleaner, which certainly helps.  It\'s also worth removing the film that build up on the wipers with a bit of vinegar (or glass cleaner if you don\'t like the smell) from time to time.
 
Rainex is also good, but can react with some polishes if you get spillages

Me too, once you get to 70 you can put them on intermittent
