Environmentally Conscious with Better Solutions In these times of increasing environmental consciousness, Twin Oaks has always been a leader. We consistently meet and exceed the Texas Commission on Environmental Quality's guidelines and regulations. Using only the highest grade solvent and changing the solvent on every run produces fresher and cleaner clothes and prevents that harsh "dry cleaning" odor. Even our poly, which covers and protects your finished garments, is made from 50% recycled plastics.
