My ears have a habit to form this yellowish wax too that needs cleaning every few weeks, as well as easily to get infected from swimming pools. Easy and cheap solution to both is to use the red rubber syringe and flush ears with the blue 70% alcohol, an top up with ear drops after flushing for a day or two.
Few years ago I got an ear infection when at home country for xmas. Felt bad enough to make me go to doctor on xmas day expecting to get some antibiotics - the ear doctor refused to prescribe any, and told most minor ear infections (like he assessed mine to be even though painful) are easily cured by good flushing with alcohol and use of ear drops after that. Worked then, and has worked since every time for me.
