Does anyone do spring cleaning?

I don't do a full-on clean out in the spring. But the sunshine and the warmer weather do give me energy and make me motivated to do some cleaning. I like to flip the mattresses and throw open the windows, air everything out. I dust everything and even get the hose and attachments on the vacuum and do the corners and edges.

Now some years I've opened the windows and let the pollen in. Oops!
