As I understand it-when the wax is heated it evaporates into water vapor, CO2 and CO, much like when a candle burns. PS--I did a google search.
Like the parchment idea though, QE

I have been using parchment as a pressing cloth at times.
No residue ... just acts as a shield between the iron and fabric.
For starch ... I've switched to Best Press ... you can get it nice and stiff, and I am finding it is not causing the scorching and residue I was getting from spray starch.
