Possible cause
Do you want to remove the darkening?
Note
Some laundry cannot be washed with bleach,
so be sure to check the washing instructions
or labels on each item. The treatment
described here may not remove all darkening.
Adding excessive a amount of softener may
cause stains on laundry.
If you add excessive a amount of detergent,
excessive foaming occurs and an operation
to reduce foaming is performed, resulting in
insufficient cleaning and overall yellowing.
Using too little detergent results in insufficient
cleaning and overall yellowing.
Depending on the level of soiling, laundry may
turn yellow even if you use the appropriate
amount of detergent and softener.

Solution
Try the following:
Soak the item overnight in a 1:3 ratio solution
of detergent and water before washing.
If the problem persists, soak whites in a
chlorine-based bleach or reducing bleach
solution, and soak colors and patterns in
a peroxide-based bleach solution. (Soak
for short periods in a sink, for example.) Be
sure to read the instructions on the bleach's
packaging carefully.
Use the recommended amount of softener.
