Just wash it as soon as you can. The sooner you wash it, the more likely you are to get the stain out. If it doesn't come out, you can always replace that spot with another patch of fur. Since it's longpile, it'll be less likely to be obvious that it was replaces.

Yeah thats what I was thinking. I'll prolly spot clean it today. I don't think it's too bad. I can just trim out the damaged parts.

Omg! I spilled red candle wax on my yellow pants yesterday. It blows. :P

Spray on oxyclean, scrub for 10 minutes.
Then hand wash with Woolite. Use a little baking soda if you need to :3

Let me know if that works!
