The soap has to be thoroughly washed with water and NaCl to lower the pH from basic to neutral, as well as to remove the lumps and bumps in the mixture, which created the soapy consistency to be able to lather and wash easy.

Does salt water condensate?
No. The reason for this deals with the nature of condensation and solutions. A solution is a liquid where the dominant liquid or solvent has other solids, liquids, or ions, in it called solutes. Saltwater is a solution where water is the solvent and the salts are the solutes. When a solution boils, the solutes and solvents split apart. For example, vodka is a solution where water is a solvent and alcohol is the solute. Since alcohol boils at a lower temperature than water the alcohol boils off before the water does. In the case of saltwater, the water boils long before salt. Condensation is when a gas turns into a liquid. Since the water vapor does not carry salt (i.e. fresh water vapor from boiled saltwater), it does not condense as saltwater but as fresh water.
