No!! I have never heard that h2o2 will burn holes in the ear, my daughter has been using this solution for years, as she has reared 3 girls and hasn't heard of it either, should I come across some information about this, I will forward it to this site.

If you are using food grade 35% H2O2, you will undoubtedly get a burn.
