I use SwimmersEar. It is alcohol with a small amount of Glycerin. ( Self explanatory)
And most importantly, lubricate the membrane.
Mineral oil is very very good.
Cheers, K.
I would NOT put acetic acid or alcohol in your ears. Although they will kill most bacteria they are also irritating to the very sensitive tissue in your ear. I use hydrogen peroxide which does not irritate the ear but still kills most bacteria.
"Historically hydrogen peroxide was used for disinfecting wounds, partly because of its low cost and prompt availability compared to other antiseptics. It is now thought to slow healing and lead to scarring because it destroys newly formed skin cells.[43] Only a very low concentration of H2O2 can induce healing, and only if not repeatedly applied.[44] ...
It is absorbed by skin upon contact and creates a local capillary embolism that appears as a temporary whitening of the skin.[48]
...
Higher concentrations may be considered hazardous and are typically accompanied by a Material Safety Data Sheet (MSDS). In high concentrations, hydrogen peroxide is an aggressive oxidizer and will corrode many materials, including human skin. In the presence of a reducing agent, high concentrations of H2O2 will react violently.
My 2 cents: Much safer (and better) to go to a GP and get some properly researched, licensed & manufactured medication. For example, although alcohol might help evaporates moisture (and dissolve things), it can have other effects too - such as hardening cell walls]:
Good point, hadn't thought of that.The alcohol was perfect for my condition as I had spent so much time in water the cells in my outer ear canals had mutated and gone all spongy, so recovering cell integrity was part of the healing process, as was correctly drying the ears after diving...
in my case I clean my sinus by physiol liquid then I use xylo comod nasal spray ,but check first with ENT ,it work for me but only one spray each nose one per week before dive only its a strong medicine with side effect .
