Avoid storing your soap in a place that is constantly in contact with water, like in the direct stream of the shower.
Because of this, the more people who use a bar of soap, the faster it will need to be replaced. More users means less time between showers and more time that the soap will spend wet.
Although some of the more fancy plastic and stainless steel soap dish designs are funky and cute, unless they have drainage, they are liable to make your soap soggy.
Additionally, you can use a loofah to help the soap last longer.
Softer water will also help prolong the life of your soap over hard shower water.
If you like using soap this way, you can put the entire bar inside the bag from the beginning.
When unwrapping the bar of soap from its packaging, make sure to do so carefully in order to avoid scraping off parts of the soap itself. Some handcrafted soaps come pre-cured, so this is not a necessary step if you have purchased this type of soap.
Cut your soap bars into halves, or even thirds, if possible. Only use one small piece at a time until it is gone.
Use a grater to scrape pieces off your bar of soap. Take 1oz. of the grated soap and put it in a jar or other kind of container. Add 1-2 cups of clean, filtered water and let it sit overnight. Stir the mixture well before use.
