I have always wondered - do I keep the soap tub's top open or closed between shaves ? The scent may dissipate when the tub is open all the time by my bar of soap in the shower stays exposed and still works fine. Will my soap evaporate quicker if exposed ? Isn't my shave puck the same as a bar of soap but what about those soft soaps or creams ? What about the water that must be now retained within the soap/puck once it has been used ? I have never known what is the best practice although some soaps make specific claims so any advise for TSC would be appreciated.
