Clean all the time

Taking showers or baths on a regular basis and keeping yourself clean all the time is a general rule to follow for good grooming. 
Using a cologne afterwards which may be subtle or overpowering for the desired effect is another step in the process. Speaking of natural men's colognes, O'Douds, Herban Cowboy, and Edens Garden are three top brands worth checking out.
And if a natural body wash is more like it, the coconut-based Puracy or Dr. Bronner's Pure-castile liquid soap will do the job well and won't let you down.
