Default Cleaning up a yeast bank

Is it possible to clean up a yeast sample with low levels of infection by plating it onto a sterile agar/gelatin sample, and visually selecting the best looking colonies for propogation?

I got to thinking about a way to maintain a samples purity threshold since I figure it is inevitable that a yeast bank will eventually develop some level of infection over time.
