There's just something counterintuitive about spraying an acid on fabric, even if it is diluted. Vinegar can also cause skin irritations, especially on babies. And for those who use it as a fabric softener, it destroys elastic.
I prewash my fabrics, iron them, and do not refold them selvedge to selvedge for storing. I fold end to end in half, quarters, whatever, and then lastly fold the selvedge sides together. The lengthwise fold is softened and the new 'creases', if any, are crosswise. They iron out easily when constructing a quilt.
