Safe Ear Wax Removal has been a topic of conversation for centuries. The ancient Greek's and Eastern Asian cultures used to use a form of curette or ear pick for removing ear wax. The ancient Egyptians used small thin braided reeds attached to a thin stick as a type of ear pick as well as ear cones to loosen the ear wax. The practice of removing ear wax will always be around as long as there are ears.
One of the reasons you don't hear much about the subject in America is due to the eew factor. Most cultures do not shy away from discussing things that are gross like Americans do. For this reason the tools that are developed in many other countries are usually much more advanced that those found in the US when it comes to disposal of bodily functions such as ear wax, mucus, and other nasty secretions. Thankfully however it is the public that doesn't want to talk about these things but American businesses are not so easily disgusted and still produce quality products.
The process of removing ear wax has not changed much in thousands of years. There really is only so many ways that you can come up with to remove ear wax without damaging the ear drum or irritating the ear canal. For this reason, people tend to use what they found to work and figure that if it isn't broke, don't fix it. The only new invention to be introduced in a long time is the disposable cotton swab. This may even end up disappearing i the next couple hundred years too. Once people get enough data regarding the number of injuries to the ear drums that occur every year from the use of cotton swabs we might see the beginning of the end of this device as a good way to clean ear wax.
The safest method for ear wax removal is still an ear wipe or damp cloth used to wipe the oils and ear wax away from the outer ear. You can't get much safer than that! Ear Candling will probably never disappear as one of the instruments used to aid in ear wax removal due to its ability to soften the ear wax and let the body push it out naturally.
