Never tried that before!

The pot pourri in the church toilets was looking rather dusty. Not the easiest thing to dust, and I wanted to deal with it fairly quickly. 

So I washed it.

And it worked!

Obviously would depend on the pot pourri - don't blame me if you try this and it goes horribly wrong.

[Edit: It ended up getting mildew, so if I did it again I'd want to dry it thoroughly]
