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. Tiny soft bristle brush included to assist in removing wax from tip/filter area. Gentle strokes across the opening to remove debris. Do not "poke" anything down the tip like a toothpick or wire as it will pop your filter and render your earplug useless.
