Long lasting powdered soap
The use of powdered soap can be considered a privilege, as it runs out quite quickly and that means a waste of money. In addition to this, the soap powder gets hideously soggy. It absorbs the moisture present in the environment and hardens, which is normal, but it still is a pain in the pockets.
The problem is easily solved if you cover the container where you have put the powdered soap with a piece of aluminum foil. Make sure it is completely covered and no air leaks can enter. This way the soap remains intact since it doesn’t absorb anything from the atmosphere.
