I prewash everything too. I only press it as I use it. I fold it nice when it comes out of the dryer, then press when needed. Don't see the need to press twice. I started using the tea rose Best Press, love it. Tried deluting it 50%, but then the smell is pretty much gone, so may not do that again. That stuff really spoils you with it's nice scent, ahh! LOL! Like to prewash though, even by hand, then I know it's one less thing to worry about....
