Are there any natural cleaning products that REALLY cut grease?
cut Lemons, cut Limes or hot or room temp white vinegar. Depending on what it is, you could heat some white vinegar to very hot (not boiling) , while it is heating you can dampen the area with water, sprinkle liberally with baking soda and then drizzle the hot vinegar onto the area then scrub it with a mildly abrasive 3m scrubber pad such as Dobie or Scotchbrite.
