Oh, mildew is quite strange, but there are some really good musty smells that exist.

Holy Stank is my favorite recipe.

Normally they require having wonderful sex and then letting a woman's natural self-cleaning nature take over as opposed to soaps or what have you.

Like the next morning, after some pure undiluted watering the night before, by hand or submersion, but not too much, and some rest, let it sweat and breathe....

Usually a fabric barrier may be required at first to mediate the strength of it down to the desired level of stank, which you want to rest your face in, but as it weakens the layers can be removed and the Holy Stank can be inhaled at point blank range.
