D.N.
I add vinegar to the wash. My son occasionally has night time accidents because he is a super deep sleeper. I add in about 1/2 cup white vinegar to the wash load . It smells when it spins the water out but does not smell up the clothes. One time the cat peed on a towel my daughter left on the floor in the basement and I let the towel soak in the washer with vinegar and it got it out.
