As always, before following these ideas, be sure to carefully read the labels on clothing, carpets, whatever you are attempting to clean.
Use 1-2 drops of Lemon oil on a stain. Let it sit a few minutes and rub off with a clean cloth or throw into laundry cycle.
Place 1 drop Rosemary oil right on the stain onto the carpet and scrub with a stiff bristle brush or directly on clothing stain and toss in the wash.
Grease Stains: Eucalyptus Oil is the best for cutting grease. Place 1-2 drops onto clean cloth, then work grease out of clothing.
