It depends on what the stain is from, Rick. Here's a link with more information:
Thanks for the reply. The stain is from a black shelving unit. The room flooded and left the stain on the rug. I will check out the website you referred me to. Appreciate it.
What is the rug made from? Polyolefin, polyester, nylon or polypropylene?
Ok thanks again. I will let you know the outcome. Have a good day. Appreciate your advice and time.
