What should you NEVER use for cleaning a compressor due to explosion risks?

Using benzene or kerosene for cleaning a compressor poses significant explosion risks due to their highly flammable nature. Both substances are volatile organic compounds (VOCs) that can easily vaporize and create flammable mists, which could ignite if exposed to a spark or an open flame. In the context of compressors, which may experience heat or electrical sparks during operation or maintenance, the presence of these flammable liquids can lead to a catastrophic explosion or fire. This makes them particularly dangerous in environments where compressors operate.

In contrast, other options such as a soap and water solution, compressed air, and heavy-duty degreasers are generally safer choices. Soap and water solutions are typically non-flammable and effective for cleaning, while compressed air can be used to remove dust and debris without introducing flammable materials. Heavy-duty degreasers, although potent, are often formulated to minimize flammability or contain safety precautions to reduce risk when used correctly. Thus, benzene and kerosene's volatility and flammability make them inappropriate for cleaning compressors.
