Naturally earwax leaves the ear without any efforts and it does not build up inside the ear to cause hearing problem, therefore cleaning of your ear using cotton buds or wax remover liquid is not necessary for most of us.
If you have wax build up in your ear and it is affecting your hearing you need to see a doctor and not doing the cleaning yourself.
It is important to soften the wax before any attempt is made to remove it to avoid causing injury. Wax softeners are known medically as cerumenolytics and there are many types of it in the market.
Olive oil, sodium docusate and hydrogen peroxide are all wax softeners available in liquid.
Ear syringing another practice used for removing earwax by doctors, in ear syringing water or saline is used to soften earwax.
Ear syringing has side effects such as swelling and ear canal infection.
Hydrogen peroxide is widely used to soften and remove earwax, however it is not without side effects, it may affect newly formed skin and damage it.
Temporarily skin whitening might occur.
Hydrogen peroxide should be avoided if there is a hole in eardrum as there is evidence that it damage the hearing. If you are going to use Hydrogen peroxide for the first time you need to make sure that there is no hole in your eardrum and only a physician can tell.
