I purchased some second-hand fuel injectors for a upgrade but cleaned them before installing them.
Please make sure you do this in a well ventilated area as when I did it even though I did it outside the cleaning products in the air hurt my lungs.
These injectors have done 20.000klm now and are still working fine.
