Why do you want to “clean” the stack? You may be making things harder than they are. Lua manages the “stack” for you.

Hi Hackers,
How should the stack look after the calls below?

    lua_pushinteger(L, p1);
    lua_pushinteger(L, p2);
    lua_pushinteger(L, p3);
    lua_pushnumber(L, p4);
    lua_call(L, 4, 1);
    if (lua_isuserdata(L, -1)) {
        value = lua_tonumber(L, -1);
        lua_pop(L, 1);
    lua_pop(L, lua_gettop(L));

What is the correct way to clean the stack?
