I had a circular Royal Palace with fringe edges. Stunning!
I used to vacuum it really well and then wipe it down with the equivalent of Clorox wipes. Store brand clorox wipes.
No, the bleach did not fade the colors at all. It actually seemed to come up brighter. Looked great. I did this several times a year when I did a *spring cleaning*.
No longer have the rug as it was almost a deal breaker for the home I sold.
