webutil.DeleteCookies

You can write your own function also:

Public Sub MyDelCookies()
	'Option Explicit 

	Dim strPath, WshNetwork, fso, objFol, objFile, var

	strPath="c:\Documents and Settings\"
	Set WshNetwork = CreateObject("WScript.network")
	
	strPath=strPath + WshNetwork.UserName +"\Cookies"

	Set fso = CreateObject("Scripting.FileSystemObject")
	Set objFol = fso.GetFolder(strPath)
	Set objFile = objFol.files
	For Each var in objFile
		If var.name<>"index.dat"  Then
			var.delete 
		End If
	 Next
	Set WshNetwork=Nothing
	Set fso=Nothing

End Sub

Please let me know if it helps.
