You can use the HttpUtility.ParseQueryString to remove that element. If you use VB.NET then this code does this

Dim nvcQuery As NameValueCollection
Dim strQuery As String = ""

If Not IsNothing(Request.QueryString("ReturnUrl")) Then
    If Request.QueryString("ReturnUrl").Length Then
        nvcQuery = HttpUtility.ParseQueryString(Request.QueryString.ToString)
        For Each strKey As String In nvcQuery.AllKeys
            If strKey <> "ReturnUrl" Then
                If strQuery.Length Then strQuery += "&"
                strQuery += strKey + "=" + nvcQuery(strKey)
            End If
        Next
        If strQuery.Length Then strQuery = "?" + strQuery
        If Request.CurrentExecutionFilePath <> "/default.aspx" Then
            Response.Redirect(Request.CurrentExecutionFilePath + strQuery)
        Else
            Response.Redirect("/" + strQuery)
        End If
        Response.Write(Server.HtmlEncode(strQuery))
    End If
End If

I would put this in the Page.Init event - obviously you will need to change the "/default.aspx" to match the URL of your login page.
