What is the most effective way to fumigate fabric luggage?

I bought an 8 dollar carry on at value village. It is of good quality and shape no stains or other issues to deal with.

It just smells awful. I couldn’t say that it stinks of anything in particular. Maybe musty with far too many assorted odors to really pick them out.

I need my carry on by Monday. Is there anyway I can be stand to put clean garments and haul it around with me without concern?
