Cleaning machines include ultrasonic cleaning machines and high-pressure spray cleaning machines. If the ultrasonic cleaning machine is used frequently, the ratio is 1:20 (5 concentrations). If it is not used frequently, the ratio is 3 concentrations. The spray cleaning machine is based on a concentration ratio of 8-10. The use of anti-rust agents depends on the requirements for anti-rust time. It can be the original solution, 1:2 or 1:3 to 1:10 and other ratios.
