Why does bleach & tap water turn black?

Question

I had a cheap plastic spray bottle that I kept by the kitchen sink. About a 50/50 solution of bleach and water. When I spray from the bottle, the bleach water sprays out black. The bottle conked out & I disassembled it & it seemed the bleach only came into contact with the plastic. I replaced the cheap plastic bottle with a brand new spray bottle and the bleach and water mixture still sprays out tinted black. What causes this? it is rather disconcerting to clean my sink and counters with black bleach. Thanks

Answer 1

Hi. You probably have corrosion of the metal spring in the pump.

Answer 2

yeah, never heard of that. How long does it take to turn black? I just tried it with my tap water and it's still clear, well a little cloudy. 50/50 mix is pretty strong. Usually 1 to 2 teaspoons per gallon of water is enough for a disinfectant.
