I really need help in removing embedded mildew stain from the cracks of my shower walls. I've tried CLR, commercial products and nothing seems to work. Do I need to remove the old grout and regrout again? (even though that won't solve the problems)
Also When our bathroom was remolded a ventilation system was never installed. Is there one that I can purchase my self and install. Because I really think that could be contibuting to our mildew growth.
