Recovered refrigerants are not automatically clean. They can carry contaminants such as acids, moisture, and oil from the system and the recovery equipment. These substances can cause corrosion, promote acid formation, and degrade lubrication, which harms refrigerant performance and can damage equipment. That’s why the correct statement notes that recovered refrigerants may contain acids, moisture, and oil—their presence means they must be processed or reclaimed to remove impurities before reuse. Other options are not correct because refrigerants are not guaranteed to be clean, acid presence doesn’t automatically require discarding (they can be reclaimed), and dumping them after use is illegal under environmental regulations.
