Ultrasonic cleaning is recommended as the most effective method of cleaning surgical instruments. Always run full cleaning cycles so that all residues of detergents and cleaning solutions etc are rinsed from all box joints and hinges.
When autoclaving make sure instruments are in an open position so that metal expansion caused by heat does not cause cracking or damage to instruments.
If carrying nail clippers with other instruments try to stop them from coming into contact causing damage to cutting edges and possibly affecting the corrosion resistance. When using chemicals always read and stick to the manufacturers recommended dosages.
