I like to start with the closets. I go through the kids, my husband and my clothes and get rid of stained, torn, outgrown clothes. I then pack up all the sweaters, coats and jeans into containers that go under the beds. (I leave a few pants and jackets out in case the weather gets cool).
Then I move on to the pantry and throw out any expired food. Then I take all the food out the fridge and freezer and clean them, throwing away anything frost bitten or old. Then I go through the medicine cabinet and throw out all the expired medicine.
Next I take down all the curtains, wash them and clean the windows while the curtains are washing. Then I take off all the bedding and turn the mattresses. Next I take all the cushions off the sofa, beat them outside and vacuum the inside of the couch.
Next I wipe down all the doors and moldings. I pull out the fridge and stove and sweep/mop behind them. Then I sweet, mop and vacuum the entire house.
After that I move outside. Pull up any weeds and get it ready for fresh mulch. I get the kids to help me clean out the garage getting rid of old boxes, outgrown toys and other accumulated junk. Once the garage is empty, I spray in down with soapy water and let it dry.
I also make the kids go through all of their toys getting rid of anything that is broken, missing pieces or that they don't play with anymore.
I'm tired even thinking about this, I better get to work :)
