Any idea on how to spray a tapestry that is over a stairwell?

I have a stairs that end in a high vaulted ceiling. There is a tapestry on one wall and air vent on the other. I am able to dust both using a long extension gadget to clean the dust off of both but I want to put some deodorizer spray on the tapestry. When ever I fry something I have to air out the house. The tapestry rarely comes down because it’s a nuisance to put back up. When ever I fry in the home the smell of grease gets everywhere. I spray curtains and any fabrics that may trap the smell but I can never get the tapestry that is in the center of the house and has a ceiling fan near it.
