NEVER LEAVE YOUR BAR IN A PUDDLE OF WATER!
Keeping your soap bar as DRY as possible is key to getting the longest use of your soap bar. This does not mean you can’t leave your bar of soap in the shower. Just keep it out of water streams as much as possible. Best if the bar is kept on a holder where air can circulate around all sides.
If a “luxurious layer” (never slime) develops around your soap bar, simply take a DRY WASHCLOTH and rub the outside layer to reveal a drier soap bar. Next, wet the washcloth and enjoy the luxurious lather!
