It was a 4 million dollar large condo right on the water in WEST VAN that she was renting and spilled WINE ON THE WHITE CARPET. My advice for next time. Right away take damp white cloths and dab the  DAMAGED CARPET. Don’t rub. She tried putting salt on it and rubbbing it out. Didn’t work!    So I came in there and cut out and replaced the damaged area with 3 circle cuts. Circle cuts show up less because the way light refracts , verses a straight line. Even though the area was large at about 18 inches square, most people wouldn’t have noticed the cuts. Another Happy customer.
