If you remove mold on the right day, there are a lot of benefits. The smell will disappear faster, the drying phase is shorter and the sogginess will not return. Remove the mold on a waning moon or new moon on an air (Gemini, Libra, Aquarius) or fire day (Aries, Sagittarius, Leo). In general, the waning moon or new moon is recommended, except on Virgo and water days (Cancer, Scorpio, Pisces).
