Due to the necessary sterilization, your hands, arms and the working space must always be properly disinfected. Disinfecting means killing all the bacteria or preventing them to appear. Good disinfecting products are alcohol and Dettol mixed with water.
Disinfecting is extremely important, but you must be careful: too much can be dangerous! A big amount of disinfecting substances in the air can damage your health. So pay attention to the quantities. After cleaning leave the room for about 15 minutes, so that the disinfecting product can do its job. Besides, disinfecting products are extremely flammable! Be very careful when you use fire in a disinfected space to sterilize certain instruments.
