I use spray starch and when the bottle is empty, I clean it and refill with water and use it when I am ironing and don't want to use starch. I use the Niagara Non-Aerosol Spray Starch and the container is plastic and gives a very nice mist. I also re-use these containers to put various cleaners in to use around the house. They work very well and I really like the fine mist that comes out. I usually will remove all the plastic "starch" covering and write on the container what type of cleaner is in it.
