Expert investigations have found that the number of bacteria on razors is 1,000 times more than banknotes, and manual razors are more likely to breed bacteria than electric razors. Clean the razor blades: replace the blades in 2-4 weeks, do not use dull blades. Rinse before and after use, and often need to be disinfected. Use alcohol and water at a ratio of 7 to 3 to disinfect the blade, which can prevent bacterial growth.
