How to rejuvenate a bar of soap
Collect a bar of plain white soap.
It can be the bar you use in your daily shower or a bar under your sink. Try getting one that does not have a strong scent, it may be hard to mask.

Pick from:
+Wash of any dust or dirt off. Just in case there is anything, if you are confident your soap is clean-move on to the next step.
+Plan to place the bar under the sink faucet. Clean the bar of soap with a soft cloth wet the underside with half of the soap.
+If the bar smells so bad that you are tempted to throw it out, wrap it in a napkin to absorb it. Muddle the fruit (and fruit goes in the bar) with your fingers or a spoon.
+Select a sponge that fits under your bar of soap. To start, pick a sponge that you can wear over the bar of soap because some soaps will have a soft face after they've been placed under the bar.
