How to dissolve candle wax (paraffin)?
Ethanol and acetone are not non-polar organic solvents. Each one has  a slight dipole moment; due to the difference of electronegativity between $\ce{H}$ and  $\ce{O}$ in ethanol and between $\ce{C}$ and  $\ce{O}$ in acetone.  Wax is composed of heavy, long-chain alkanes. And as "Like dissolves like" try to dissolve your wax in toluene or in xylene.
