I, too, have struggled with this issue. In my town, the water leaves a whitish film on glass shower doors. Nothing I have tried (yet) works well to remove it. And those huge Roman tubs? UGH, I hate cleaning those! Hardly anyone uses those tubs, but they get dusty anyway. Bathrooms can be time consuming, and I have to budget my time so I DONT spend too much time on them. And then there is that perennial issue of clutter. Most people keep a collection of cosmetics, facial cleaners, tissues, etc etc., on bathroom counter tops. I dont know about you, but I cant remember exactly where 20 items were before I cleaned!
People are happy how I clean their bathrooms, so I must be doing something right. But it can be frustrating.
