UGG/ EMU boots how to get rid of the tied marks?!?!?

this happened to my Uggs, I filled up my sink with warm water and added a little bit of laundry detergent, I completely soaked them and used a soft scrub brush on the marks, I rinsed them and lightly wrung them out and put them next to my heater. just make sure they dry completely before wearing them, and if the inside is taking a long time you can use a blow dryer to fluff the fur
