Cotton swabs (Q-tip) are number one cause of earwax blockage as they push most of earwax deeper. Thin and rigid ear cleaning tools can go too far and damage ear canal or rapture the ear drum.

Ear candles are inadequate and hazardous.

Liquid solvent and irrigation methods feel uncomfortable with messy discharges in and around the ear (though in case your earwax accumulation issue is bad, and your earwax is harder than normal soft earwax you might wish to use both wax softener drop and Ear-O-Care simultaneously to soften the hard wax and pull it out).
