My Macy has Ear Problems. I got a solution from my Vet that I put in her ear and rub. Then I let her shake, which usually brings most of the gunk out.
What I do for cleaning is I went to a Beauty Supply Store and got some of the cotton they sell for going around the neck. It is maybe 1/2 before you twist it and you can break off what ever length that you need.
As I said Macy has had ear problems as long as we have had her, so i clean them quite often. All of the supplies for cleaning and medicating her ears are kept in a Canvas Tote Bag. Well, all I have to do is pick up the bag and she hides. She is fine once I get her to relax but it is funny to watch her reaction to the bag.
