i just rented a yamaha YFL 261... it`s in pretty good shape, it`s open hole, which kinda made me nervous.. it`s my first flute, and for now i`ve been playing it with the hole plugs on, and it works pretty well like that.. i was just wondering, is their anyway to remove minor scracthes? like with polshing or a special cloth? any tips 4 a beginner?

thanks...
