We have hard water and I'm always in an ongoing battle with the shower door and dried water deposits on it.
With a lot of nagging I've now managed to get everyone to squeedgie the door after showers (well mostly 
), but I still have to scrub it regularly with various cleaning products. And it's a job I hate too, cos I get wet, bang my head and the cleaning stuff makes me wheezy.
So would a Karcher window vac solve all my problems? Or will I still need to scrub? The advert shows it gliding over glass and leaving it sparkling. But after the disappointment that was my steam cleaner, and which I barely use, I'm dubious as to how effective it could really be.
Advice gratefully received with thanks
