Are dryer sheets dangerous? What toxins do dryer sheets contain that could harm your kids, your dogs or your family? Let’s investigate! Bounce supposedly produced the very first dryer sheets in 1975, which is why I don’t really ever recall my mom using them in my youth (that will date me!) In fact, I distinctly remember my mom saying “Don’t be ridiculous!” when I suggested she buy them (hey, I liked the way my friend’s clothes smelled…and I didn’t know what I know today LOL) Dryer sheets were created to “solve” the problem of static cling in clothing, and prevent static electricity from causing clothes to “stick together” in the dryer.
