Residual Bleach after Washing

Advice from Dr. Laundry
Q.

What is the probability of having a problem with the load of laundry done after the load of whites due to residual water containing bleach retained in the machine?

A.

This shouldn’t be a problem if you add the bleach directly to the load as the water is filling and before the clothes are added. If you use a bleach dispenser, I always add some extra water to the dispenser after adding the bleach as an insurance policy. If you want a little extra peace of mind, do a light colored load following the white load. They would be much less likely to have colors sensitive to any residual bleach.
