It’s amazing how much fluff and dust builds up on surfaces like the bath and sink, mostly because it sticks to the damp surface. That’s why I've always advocated drying down surfaces after a shower or bath, leaving some time for the water vapour to go out through the windows or extractor fan (although it’s hard to completely avoid condensation). It doesn't always work out that way though, especially if you’re in a rush to leave the house. I also don’t like to spend an awful lot of time cleaning as I think there are far more constructive things to do with your time, so I try to get the bathroom clean in as little time as possible. Whereas my mum used to take hours to clean the bathroom from top to bottom, I generally take about 15 minutes and still manage to make it look nice and shiny.
