Many dry cleaners place cleaned clothes inside thin clear plastic garment bags After the drying cycle is complete, a deodorizing aeration cycle cools the garments and removes further traces of solvent, by circulating cool outside air over the garments and then through a vapor recovery filter made from activated carbon and polymer resins.

Most dry cleaning in Austin TX uses this process. First, garments are placed into a washing/extraction chamber.
The chamber fills approximately one-third full of the solvent perchloroethylene (also called perc), and the chamber begins to rotate, pushing the solution through the clothing.
This study is a comparative analysis of two professional clothes cleaning methods: traditional perc dry cleaning, and wet cleaning which uses water and biodegradable detergents in sophisticated washing machines (70 percent) in conjunction with a hand-washing method called.Download
