I was worried about the over spray of the starch, I had a LOT of fabric to spray...so I decided to spray the fabrics over the bath tub and then I was hanging them on hangars on the shower curtain rod... Well that evening I went to get in the shower and the bath tub floor was like a skating rink!!! :shock: :oops: :oops: I did not get hurt, but to this day I do NOT know how I kept on my feet :roll: :roll: I still spray over the tub if I have a lot of fabric, but I always rinse it out with hot water the minute I am done!!!
