There is no rule for the number of times a stain needs to be poultices. Generally if the stain is slowly disappearing I would continue to poultice. The average number of poultice applications will be about five.
TIP If after the first two poultices you see no improvement, you may be using the incorrect chemical. Refer to a stain removal chart and to my book “Stain Removal Guide for Stone”.
