hi, my name is bonnie~ im currently a year 12 student in australia studying textiles

i was wondering is there ANY ANY ANY way to bleach POLYESTER velvet? because i read somewhere else that polyester would be good for Devouring on velvet however i can not reach any of the paste in australia. My garment is polyester velvet and i would really like to bleach out my pattern but it's not working...
could anyone please give me some help or handy tips. it would be very much appreciated~
