To maximize your own results, it would be best to clean your house first and clear as much clutter as you can. Also, just before you start, take a few minutes to think through and get clear on your intention for the house and the results you expect. You might even want to write it down.
(1) Take a saltwater bath to clear your own energy
(2) Drink a full glass of water just before you start the clearing process
Preparing Your Home...
(1) Light an aromatherapy candle in every room of the house and keep them lit throughout the process.
(2) Open a window in every room. If it's incredibly cold, just crack the windows! Even that will help the energy disperse.
