So here is really a listing of tips on how to bowl reverse swing
Shine the ball a lot making the rough side of the ball as rough as you possibly can. This can also be achieved by bowling the ball across the seam and bouncing it to the keeper when fielding.
Reverse swing was made famous by Waqar Younis and Wasim Akram within the 1990's. This pair is still regarded as the most destructive advocates of reverse swing of all time. Throughout their careers they made the ball reverse very late, at pace, and at will. They generated such prodigious swing, that they are once charged with ball tampering. From a batsman's perspective, it is much easier for them to assess conventional swing, by picking the ball's seam position. In comparison the reversing ball is much more difficult to judge ' because the reversing ball tends to move later in the trajectory.
Now let's learn to bowl reverse swing. Reverse swing is a phenomenon occurring later in an innings, around the 40 over mark once the ball is beginning to wear. As cricket balls become more scuffed, they start to take on different characteristics. When this happens the ball 'reverses' - such that the behaviour from the rough side takes on the shiny side. Therefore a ball delivered as an out-swinger now becomes an in-swinger and the other way around.
