Scanning paper docs. to .pdf often results in random dots and speckles appearing on the pages.  What tool in Acrobat DC do you use to remove or erase those random dots or speckles?

(I just downloaded DC.  I learning how to use it on the job.  The Adobe salesperson who sold me the produce on July 19, 2016 assured me that DC had such a built-in erasure or removal tool for the removal of random dots and speckles.  So, I want to know where that tool is located in DC.)
