Can soap nuts be used in my high efficiency (HE) washer?
Absolutely. Because soap nuts are low sudsing they work EXCEPTIONALLY well in these washers. You may use the wash bag method (putting it directly in with your laundry) or use soap nuts liquids as directed. Soap nut liquids can be used either by being poured directly in with your laundry or the detergent dispensing compartment may be used as directed with any HE detergent. Frankly, I consider soap nuts to be the best high efficiency detergent available.
