What are the methods for cleaning titanium rods?

1. Alkali cleaning: Soak in 3-5% sodium hydroxide analytical pure solution for 30-60 minutes at a temperature of about 40 degrees. Better in ultrasonic cleaning machines. After soaking, rinse with filtered deionized water or water for injection inside and outside until neutral, and measure the conductivity. Blow dry with pure air at a pressure of ≥0.4Mpa.
2. Pickling: Soak in 5% nitric acid solution for more than 8 hours at a temperature of 40 degrees. Better in ultrasonic cleaning machines. After soaking, rinse with filtered deionized water or water for injection inside and outside until neutral, and measure the conductivity. Blow dry with pure air at a pressure of ≥0.4Mpa.
3. The above two methods can be used alone or in conjunction with each other. If possible, it can be combined with an ultrasonic cleaning machine for better results.
4. Organic matter pollution can be combined with surfactant cleaning, and cell debris pollution system combined with enzyme cleaning effect is more ideal.
