What is a good cleansing ritual/spell to cleanse my altar room after hubby's surgical healing?

to clarify... My altar room, was used as a wound-cleaning room after hubby had major surgery, and I was not in the least happy to have my NEW altar room taken over by him. It is also my craft room, ( i crochet....alot) and I watch tv there too. Needless to say, it was designated as MY room. I have spent the better part of 2 hours looking for a simple ritual/spell for make the room my own again and banish the ,if any, lingering illness, or negativity so I can do any further rituals, ie, Ostara, athame dedication, wand dedication... ect. Any ideas?? Like what secnt candles, herbs, ect. Help!!! Since there is no more sickness,ect, that is where I am stumped.
