Do laundry detergent sheets actually clean as well as liquid or pods?

The reviewer consensus is 'good enough for lightly soiled travel laundry, weaker on tough stains.' Consumer Reports' testing of liquidless sheets found they removed dirt acceptably but underperformed on tannin (coffee) and protein (blood) stains versus liquids. For sink-washing worn-once travel clothes, most reviewers say they're fine; for a week of stained gym gear, pack a stain pre-treat.
