Washing clothes

[Guest Ahmed]

Hey!

I wash clothes by putting my najis clothings in a semi auto washing machine and pour kurr water on it. Then I throw in detergent and get it washed for 15 minutes. After washing it, I take out each cloth individually and rinse the detergent with kurr water and rinse 2 more times. 

Does this make any type of impure cloth pure? (Whether it be semen, blood or urine)

Per my understanding of the following rules of purity, it will become pure:

It is best though, to purify the najas clothes separately and then put it into washing machine, simply to save on water. You won't need to wash and rinse 4 times just to make sure najasah is gone.
