Hello, My wife and I swab our ears and nostrils with 3% hydrogen peroxide any time we feel a cold coming on and she hasnt had a cold since 2014 and I havent had one since 2016 ( I felt it coming on that night and stupidly waited til the next morning to swab, LESSON LEARNED ). Now I always swab right away.
