For blocked ear,,,or to clean your ears....get some grapefruit seed extract....Put into a cup of warm water about 10 drops...
Get one of those blue "baby" rubber bulbs, and suck up some of the warm water / gse into it.....
Hold your head sideways over the sink and shoot the water into your ear, let drain out in sink.....do several times...sometimes there is just built-up wax in there which will soften and come out.
