Oxy clean! I have used this on blood and multiple stains. I've even used it on stains that had been through the dryer and it works. Not sure why, but if you have any chance, it's this.
For grease stains on fabric, treat the stain as soon as possible. Pour liquid dish soap generously on the stain, rinse with white vinegar, and wash as usual.
Look for the liquid dish detergent that you normally use to wash dishes.Mix it with some water add it to the grease stain and wipe it,if it does not come off try it without mixing water.
