How should I store the bar between uses to make it last as long as possible?

Because the bar relies on sodium palmate for firmness, prolonged contact with water will soften it and shorten its lifespan. Use a soap dish with drainage slots or ridges so water runs off rather than pooling under the bar. Place the dish outside the direct spray of the shower or bath — constant splashing dissolves the surface faster than actual use. After each use, give the bar a quick shake or tap to shed excess water. In a humid bathroom, consider rotating two bars so each has 24 hours to fully harden between uses. If you take the soap to a sauna or steam bath, bring it in a ventilated container and let it air-dry completely before returning it to the dish. Proper storage preserves the dense, creamy lather and the fresh conifer scent for the full 140 g.
