We love cow hide rugs and both Bethany and I have them in our homes. What we didn't know is how to clean them. Recently we steam cleaned our carpets with my Bissel Pro Heat steam machine just using some oxyclean in hot water. It works great on wall to wall carpet and on our area rugs, so we gave it a try. It worked wonders!
We shampoo our horses, so why not a cowhide?
This left the hide shiny, pleasantly fresh and clean. We air dried it in the sun outdoors for several hours. BTW these rugs are the most durable and forgiving rug out there- you can't hurt them, and they're great with kids,spills and animals.
Here is one layered in Bethany's living room.
Hope this helps clean your hide!
