Spent (used) mineral spirits normally represent the largest waste source of vehicle repair shops. Following the DOs and DON'Ts will save you money, and make it easier to stay in compliance with environmental regulations. Many older parts washers use mineral spirits, Stoddard solution, and petroleum naphtha that may be hazardous due to ignitability. Avoid contamination of non-hazardous mineral spirits with other hazardous wastes (e.g. brake cleaner, carburetor cleaner, etc.).
