I bought a white Viscose rug from Restoration Hardware last year and I spilled some red wine a few weeks ago. I was very mad since I had a viscose rug in the past and when I had it washed from a local company, they completely damaged the rug. I looked online from a different solution and found revitaRUGS. They are probably the only company that can wash bamboo silk. The rug looks like new when returned.
