Audio cassette problem

I know this is old technology,but I have a cassette that has music
that is out of print now. It plays but.some of the tape sounds garbled
and bad. My question is is.there anyway I can clean off the tape or something to save it.
Thanks zap em.
p.s. Where is that aisian web site where I can purchase spiderman 3?

The movie is not released yet for purchase. This thread is closed.:cop:
