Windowless bathrooms, any tips?

[Potteresque97]

I've got two windowless bathrooms and although I open the available windows regularly, they don't smell fresh. Any ideas? I change the towels regularly, clean round 1 x per week and mop the floors.

Do you have a decent extractor fan?

I had them both changed last year, they sounded pretty decent so I don't think it could be that.

Hmm. My en suite is windowless. I hate it. But I can open the bedroom windows and air it well that way. Have you tried one of those dehumidifier thingamys?

Maybe that is a good idea, it does have that kind of humid smell about it.

Do you leave the door open when it's not in use? I always wedge mine open with the bathmat. May help?
