Garbage in, garbage out. You can avoid data cleanup tasks on the backend by avoiding bad data coming in.  ASP.NET validation controls and third party validation controls help you receive the right data in the right format.  In addition, the AJAX Control Toolkit employs extenders that can prevent invalid data from being entered in the first place.  For instance, the FilteredTextBoxExtender can prevent unwanted characters from being entered into the textbox.  The MaskedEditExtender restricts the format of the input being entered.
