7. Glycerin for Ear Wax Removal
If you read the labels of some of the commercially available ear wax softener drops, you will find glycerin as one of the ingredients in most of these drops. Glycerin is an effective wax softener due to its moisturizing and lubricating properties. It is also considered safe to be used when it comes to ear wax removal at home. Although glycerin can be put into the ears undiluted, its better to dilute it with some water due to its viscosity. Water makes glycerin a little thinner so that it may easily go deep down to soften the wax impacted there under.
