Dry cleaning
Liquid silicone (decamethylcyclopentasiloxane or D5) — is gentler on garments than perc and does not cause color loss. GreenEarth Cleaning  charges a license fee for using this solvent. Though considerably more environmentally friendly, the price of it is more than double that of perc, and GreenEarth charges an annual affiliation fee. Degrades within days in the environment to silica and trace amounts of water and CO2. D5 produces nontoxic, nonhazardous waste.
