Cut a green scrubbie to fit the space you keep your currently squishy and slimy (gross!) bar soap.
You can use anything that doesn’t absorb and hold liquid or rust in place of the green scrubbie. There are cheerfully patterned cotton scrubbies available from Freedom furniture and The Design Store.
Keeping the bar on top of the scrubbie should be enough to lift it out of any sitting water.
It’ll also stop it sticking to the surface it’s sitting on and reduce the unbelievably-difficult-to-clean hard layers of dried soap goo.
Just rinse out the scrubbie in hot water every now and then.
One less thing to do!
