If you want to maintain your Earasers to the absolute max, use this kit. Each wipe is custom formulated to provide a germicidal wipe, which kills all bacteria that could possibly form on the surface of your Earasers. This will help keep your filters operating at peak condition while making sure that your hearing health is optimized. We suggest one wipe every other week. If you use Earasers daily, and if you have more wax production than average, you may also want to increase the use of wipes to once per week.
