Look into substitutes carefully. When considering substitute raw materials, ask questions and get documentation. Solvents, particularly chlorinated solvents, may be toxic, flammable, highly volatile, dissolve landfill liners, carry other toxics, and contribute to smog development or ozone depletion. Because of problems associated with their use and disposal, try to use other types of cleaners. The SAGE - Solvent Alternatives Guide web site is an excellent resource.
Terpenes are oils isolated from plants through gentle heating or steam distillation.
They are less toxic and more biodegradable than most solvents. Limonene cleaners are terpenes made of lemon or orange oils. Check the MSDS for this information. Lower air emissions mean a healthier work environment. Remember to contact your commercial laundry service to discuss what materials may be on the cloth.
