Can i wash my curtains?!

So my curtains in my living room are absolutely destroyed by the kids mucky handprints all over them they're gross! Problem is they are dry clean only and being the cheap skate I am I don't fancy getting them dry cleaned. Do you reckon I could put them in my washing machine. My machine has a handwash setting which I have put shoes and hand wash only teddy's in and they've been fine.
