I use a very cheap vodka with water for my spray. Vodka is made from potatoes or wheats but the is perfectly clear. I mix 1/3 cup of vodka with 3 cups of water. No cooking needed. I put the liquid in a "mister" bottle to spray, not a spray bottle. Just need to spray the fabric and iron it. No waiting! A cheap bottle of vodka lasts me more than a year!
