I use a tablespoon of cornstarch to two cups warm water put in essential oil (flower) shake it up. You need to shake it everytime you use it. The best way to use any starch is to let it penentrate the fabric before you iron it. You need to put it in a spray bottle. I also buy a bottle of starch and mix it. If the sprayer becomes clogged put it in hot soap water and it will on clog. Make new every couple days it get old.
