Can a bar of soap get dirty?

Technically yes, but it’s not something to lose sleep over. Germs do like to live on bars of soap, but they are typically washed away as you wash your hands. A few studies (which, keep in mind, were funded by soap companies) have been conducted on this matter, and no soap germs lingered on any of their participants’ hands.

To decrease the amount of germs on your soap, make sure it dries out between uses—bacteria like damp, slimy soap best. Also, if you rinse your soap before use, you can send many of the remaining germs down the drain.

Of course it can, but you can just simply wash off the dirt

Because soap molecules have both polar and non-polar properties, they're great emulsifiers, which means they can disperse one liquid into another. ... So, yes, soap does indeed get dirty. That's sort of how it gets your hands clean: by latching onto grease, dirt and oil more strongly than your skin does.

So, yes, soap does indeed get dirty. Dirty soap can't clean itself, though. A contaminated bar of soap gets cleaned via the same mechanical action that helps clean you up when you wash your hands: good ol' fashioned scrubbing.

Yes, especially if one scrubs out his/her caboose thoroughly. I do, then I 'wash' the soap iself before placing it in the soap dish.
