Anthony, I'm just using diluted white vinegar..half warm water/half vinegar. It really only takes a tablespoon or so. I wet the cotton ball, wring it out well...then wipe out his ears. I reach as deep into the ear canal as I can...OH the crud in there!!!!! I clean his ears every week. I can't imagine what might be in there if I let it go beyond that! It cleans them so well...wayyyy better than the oto-clens stuff I got from the vet. Since I don't seem to have to wipe so much, it is less irritating.
And yes, Renee......that boy LOVES any and all attention.
