I need to really wash the blinds in my new house. Just wiping them down isn't going to cut it. I took some down and put them in a closet while I painted the room. When I opened the closet, the closet stank of rank dog. Hence, I'm pretty sure that the dog smell is in the blinds. They are not wood...they're plastic or composite of some sort. What can I use to wash them? I just don't want to yellow the cords in the blinds, though. Thanks for any info.
