title: Practice tip. Which cerumenolytic?
abstract: OBJECTIVE
  To test the in vitro dispersion of ear wax by four commonly used cerumenolytics.
  
  
  METHODS
  Equal parts of the same piece of ear wax were covered with 10 mL of each preparation and observed for up to 30 days.
  
  
  RESULTS
  Sodium bicarbonate and Waxsol dispersed wax within 2 hours, Cerumol was much slower and olive oil had no effect.
  
  
  CONCLUSIONS
  The cheapest and most effective cerumenolytic is a solution of sodium bicarbonate.
