I wonder if it really works. If it did, it may well be worthwhile! Both I and the wife have earwax buildup issues every few months. The drops you buy in the store barely work (takes max treatment each time and really doesn't get the job done well). The home remedy of H2O2 is completely ineffective. The only thing that *really* works is the water hammer thing that urgent care has. That knocks it out in no time flat, but going there to have it done is pricy...
As someone whose husband has regular buildup, here's what they do at the offices around these here parts (and that is very cheap to do at home):
Gently heat half hydrogen peroxide, half water in a 2-c size measuring cup (to 100f or so, not burning)
Place ear-wax-sufferer in horizontal position, put a cup of hydrogen peroxide in their ear (one side at a time, please), for 2-3 minutes
Place sufferer upright in a bathtub, and plan to get a bit wet.
Place warmed water-HP mixture in an earwax removal syringe (~$7) and pump into ears using diagram in box - it's designed so you can't do damage
Repeat 10-15 times per ear until buildup is removed.[/li][/list]
Total cost: Under $10, a whole bunch of eeeeews, and a bathtub cleanup. Much cheaper and less painless than visiting a doc 1-2 times/year. We've been doing this for three years with no ill effects.
