Dry cleaning isn’t actually dry. Your clothes go into a machine with a liquid solvent (not water) that dissolves oils and stains, then the solvent is filtered and the clothes are gently dried.

Non-toxic solvent enables near-perfect recycling of mixed-fiber textiles

We are producing more textiles than ever before: worldwide, well over one hundred million tons of textiles are manufactured every year—more than twice as much as in the year 2000. This makes it increasingly important not to simply throw away old textiles, but to recover them in an environmentally friendly way. That is often not easy—especially when it comes to blended fabrics, such as mixtures of cotton and polyester. At TU Wien, a new method has now been developed to separate and recycle such mixed textiles efficiently—in a remarkably simple way, using menthol and benzoic acid, two nontoxic substances. The research is published in the journal Waste Management.

One area has been reducing the use of volatile organic solvents and replacing them with ionic liquids (see figure 18.13).

In preparation for its display in Jeffrey Gibson: When Fire Is Applied to a Stone It Cracks at Brooklyn Museum, the bronze relief of Charles Rumsey’s Study for Buffalo Hunt needed to be cleaned. It had previously been displayed for years outdoors. It was covered in a thick layer of wax and resin applied over decades as protection. The coatings had turned brown and absorbed dirt. Wax and resin were no longer necessary since they were not original and the object would be indoors. However, the coatings had become impossible to remove except with extremely harsh chemicals like paint stripper. Using a special laser, however, it was possible to remove this coating without dangerous solvents. The old, dark coating is on the left, the cleaned surface on the right.
