What should you pay attention to when using laundry detergent?

1. Do not mix laundry detergent with soap. Because washing powder is acidic and soap is alkaline, acid and alkali will neutralize when mixed, which will reduce their respective detergency.
2. When using washing powder, the clothes must be rinsed clean. If close-fitting clothes are not rinsed clean, the washing powder remaining on the clothes will damage the skin. People with allergies may have allergic reactions if they use enzyme-added laundry detergent or wear clothes washed with enzyme-added laundry detergent.
