>     what is involved in cleaning it? 

    Any method that works for you. 

    If the casting house has the equipment you can request they tumble
    it. This gets into all the nooks and crannies. Less work for you. 

    Rubber wheels on a flex shaft. I prefer those soft blue wheels. Form
    fitting. 

    If you mean entirely by hand, yeah sandpaper would do it.. If you
    need to true up flat surfaces use a file. This leaves cutting lines
    which can be reduced by using a fine file in a circular motion after
    you've planed it off. Then polish as needed. 

    Unless you mean your castings are coming back with investment still
    stuck on. It can be picked off. If there's a lot of it you should
    talk to your caster about why its there. 

    My own pet peeve (well, one of many) is when the caster uses a coarse
    large abrasive wheel and just goes hog wild. pointless. arghhh
