As far as I can see, there are no stains. I have only washed it at home. Also, I have a cat, so if you have allergies, please be aware that I have taken precautions, but if you are concerned about cat hair or odors, please refrain from purchasing. It has been some time since I purchased it. Please refrain from purchasing if you are looking for a new item. I look forward to your purchase if you understand.
