Sometimes yellow is color change of the plastic, and sometimes it's just crud.  Our current home was rather yellow inside when we moved in.  After I sprayed everything with windex and wiped it all down, it was back to white.  The yellow was simply a large amount of tobacco residue from the chain smoking late owner.
