How do you clean the thing? We have lived here four years and this blind was already fitted, it seems to be a proper bathroom/kitchen one (neighbours at the back have it in their kitchen) but it now has started to get mildew spots over it.
The bathroom only has a window, no extractor and it is normally left open the vast majority of the day and post baths/showers.
How do I clean it as I can't afford to replace it?
