A picture would definitely be best, but my first suspect would be mealy bugs, they're a very common pest on houseplants. What I usually do for them is take a q-tip dipped in rubbing alcohol and wipe them off with it. When I've had them, they were usually on the stems and around where the stem joins the leaves, if the stuff you're seeing is just on the leaves then it's probably something else.
