It’s not that high tech.
Buy a bottle of Hydrogen Peroxide from a drug store. The typical bottle is mainly water with less than 5% peroxide. It won’t injure you. Lay down on your bed on one side with one ear up towards the ceiling with a towel underneath you head. Pour some peroxide in the cap and then pour a capful into the ear. Let is sit for a minute. You may notice some bubbling, which is wax dissolving, and some heat may be generated. That’s normal.
Then rinse the ear over the sink. I use one of those rubber bulbs that can be used to aspirate snot from infants noses, usually about $2 at the drugstore. Fill with lukewarm water from the bathroom sink and then gently insert into your ear. Don’t try to ram it all the way through your eardrum. Squeeze the bulb while standing over the sink.
Repeat for the other ear and let your ears air dry.
There are commercial kits for these and they usually substitute a syringe for the bulb, and their peroxide solutions contain some additive to make it smell nice. Use one of those if you aren’t comfortable with what I’ve written.
If you think you might have an ear infection-usually these are quite painful- see a professional and don’t do this. Same with a busted ear drum. Again these are painful conditions that usually aren’t subtle.
