Aust Fam Physician. 1999 Aug;28(8):817, 828.

Abstract

Aim: To test the in vitro dispersion of ear wax by four commonly used cerumenolytics.

Method: 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.
