Is a mixture of 1 cup bleach and water the best way to remove any suspected mildew from my concrete floor? I do not have any external ventilation in my basement, but my house is electric. If bleach is the best solution, do I need to be concerned about any buildup of dangerous fumes? Also, do I need to thoroughly rinse the bleach off or just damp mop the floor with some clean water?
Thanks in advance for any replies.
