I read a few years ago that cleaning your ears with q-tips can lead to your ear canal to get blocked up by compressed material and weakens the ear’s defense against stuff that might enter it. The ear actually does a pretty good job at keeping itself clean.
And then there’s the danger of causing damage to your own ear by trying to clean it.
Ever since then I only cleaned them superficially, e.g. under the shower, because no one likes to have visible traces of ear wax. Never had any problems.
I recently saw an ad on TV that I thought was pretty funny, but it actually makes sense in a weird sort of way. Just Google “WaxVac commercial” and it should be the first result (if you’re interested).
I’ve always used cotton swabs or occasionally held my ear under the showerhead for a few seconds.
