Cleaning wax from a Silver Electroform

Hello Friends,
We are a silver electroforming company.
We are making hollow silver jewelry and articles from electroforming over a wax mandrel.
We remove the wax mandrel by drilling holes in the formed silver by heating the electroform.
The problem we are facing is to clean the surface of silver after removing the wax.
We request some friend around to suggest us a procedure to clean/remove the wax efficiently and subsequent cleaning process.
Does wax dissolve in any solvents?
We have tried acetone, NC thinner, metal cleaning powders, boiling water, H2SO4, HCL, Ultrasonic and various other options.
Replies are eagerly awaited.

Try turpentine [on eBay or Amazon] or gasoline, it must work.Be careful-very flammable! Hope it helps and good luck!

If you have a number of these to clean per day a vapor degreaser is a very safe and easy way of removing wax and other contaminates such as greases and oils. I would recommend you use an n-PB based solvent as well instead of TCE.

If you go the vapor degreasing route, you will need to establish controls or it will pit the tank and the part. I like vapor degreasing.
