Not a bad idea, but I am not sure my son even knows where the washer is.
Teach him before college.
Both my kids did own laundry at age 15. They have those Tide pods now all they have to do is throw one in and turn it on. Daughter found something called color catcher-looks like dry fabric sheet, goes in washer and catches colors if they mix all together at once. Works. We just soak whites in oxy clean then spray then wash. Usu good enough.
