We recommend the use of a ‘Wet Stain Remover’ for liquid stains. But first, the stain must be firmly blotted before applying any stain treatment. If you do not have any Wet Stain Remover, dilute the area with luke warm water (not hot water) and blot again thoroughly using a clean dry towel or paper towel. Make sure you do not rub the stain. You can continue to gently apply water and re-blot. The wool pile will not be damaged by water as long as you do not over-wet the wool. The good news is most oily or greasy stains can be removed, even after a period of time.
