I've regularly used Dow Scrubbing Bubbles on my shower. While it never bothered me too much, I thought that product had strong fumes and probably wasn't safe for my health. So I switched to Seventh Generation Shower Cleaner.How shocked was I when the first time I used it I felt burning in my nose and the back of my throat. I spent the next hour coughing. And no, I DIDN'T inhale any of the mist. This product DEFINITELY has fumes and smells awful. That was a week ago.Hoping it was a fluke (giving the product the benefit of the doubt, I hypothesized that it had released toxic chemicals that had built up in my shower), I tried the product again this evening. SAME result. That was about 45 minutes ago, and I'm still trying to clear the irritation in my nose and throat.As bad as I THOUGHT Dow Scrubbing Bubbles was, that product NEVER had this effect on my health. Seventh Generation Shower Cleaner is definitely NOT recommended.
