If you want to make the exported result tidy, it's best to completely avoid VF constructs and use basic HTML. Here's an outline of an export that I've used in the past:

    <apex:page standardController="Object__c" extensions="anExtension"  showHeader="false" standardStylesheets="false" sidebar="false">
    <head>
        <meta http-equiv="Content-Type" content="text/html;charset=UTF-8" />
    </head>

    <table>
  <tr>
    <apex:repeat value="{!$ObjectType.Object__c.FieldSets.FieldSetName}" var="f">
      <th>{!f.label}</th>
    </apex:repeat>
  </tr>

    <apex:repeat value="{!myList}" var="item">
      <tr>
        <apex:repeat value="{!$ObjectType.Object__c.FieldSets.FieldSetName}" var="f">
          <td>{!item[f]}</td>
        </apex:repeat>
      </tr>
    </apex:repeat>
</table>
</apex:page>

The standardStylesheets="false" solves the bit that you were asking for. You'll probably want the Content-Type tag in case you have any accented characters in your data. And by using raw HTML you don't get odd bits of VF tags hanging around.

I found that the removing <apex:form> and </apex:form> from the visualforce page stopped the extra css data appearing in excel.
