Hi Teena,
You may need to take off the sealer on the affected Tiles and then re-seal, its the only way you will get a nice finish really, added to that your on a vertical surface so you may be best doing all the Tiles underneath the damaged ones as well at the same time, for more info on cleaning and sealing Travertine Tiles click on the link below.
