Answers. Best Answer: It's fine to reuse ear plugs as long as you clean your ears each time before inserting them. You'll need to replace them occasionally, depending on how often they're used. I've found that the yellow cylindrical ones work better and stay clean longer than the standard orange ones.
The ear is actually self-cleaning and for most people ear canals do not need to be cleaned. The best thing you can do for your ears is to not put anything in them that is smaller than your elbow. Wax is not formed in the deep part of the ear canal, but rather the outer part of the canal near the external opening. If left alone, old earwax naturally migrates out of the ear as a result of jaw movement.
