I had been noticing that my clothes after washing were not looking as clean as I know is possible. I decided to try the probiotic washer cleaner from Frigidaire. The scent of the mixture is really nice. I follow the instructions on the label. I feel as though maybe I missed a step or something but I double checked and I had not. I set out to wash my whites and I do not see a large difference. Maybe after consistent use of the probiotic washer cleaner I will see consistent improvement but at this point I could take it or leave it.
