The ear wax removal kits are available in drug stores and elsewhere (put hydrogen peroxide based thick goo in ear, let it set for a while, and remove it with warm water injected by a rubber bulb squirting thing), and I've been using that method for decades (a doctor recommended this stuff when I was playing guitar in loud clubs many years ago). Works great and is safe.
Those do work well. I use Nivea body wash, and make sure to lather my ear really well, and rince with the shower head over 15 seconds per ear. That seems to, over time, keep my ears pretty clean.
However! That requires regular maintenance. The bulb works best for build up.
Best,
