Abstract
A system for cleaning a workpiece comprises: a vaporization zone containing a first solvent and a second solvent, wherein the first and second solvents are at least partially immiscible with each other such that they form a liquid with at least two phases; a heating element configured to facilitate the vaporization of the first and second solvents, producing vaporized solvents; a condensing zone configured to receive the vaporized solvents from the vaporization zone; and a support configured to retain the workpiece in a position to receive the vaporized solvents for condensation on a surface of the workpiece.

A method for cleaning a workpiece, the method comprising:
- providing a first solvent and a second solvent, wherein the first and second solvent are at least partially immiscible with each other such that they form a liquid with at least two phases;
- transferring vapors of the first and second solvent to a condensing zone;
- and
- condensing the vapors onto a surface of the workpiece to remove contaminants.
