Whatever you do, don't use bicarbonate of soda as previously suggested in a old thread! I took that advice and all it did was make it worse. You could try buy an UGG care kit and use the cleanser bottle in the kit to wash the stain out. Some people recommend blotting the stain and then letting it dry, put brown paper over it and iron. The idea is that the brown paper and heat will absorb the fat from the stain. Personally I found not much worked (I dropped a knife that had butter on it). I had other problems with the boots (bagging dreadfully and tread on soles peeling off after a month of wear) and returned them to QVC for a refund in the end. I bought a pair of UGG boots instead which have been better. I had a little stain on one boot and successfully used the cleanser from the kit. The trouble with Emu is that the boots are now waterproof treated so when you try to wash a stain out the sheepskin goes funny and it dries hard afterwards. I don't have this problem with UGGs despite spraying them with UGG sheepskin protector. Good luck with removing the stain.
