If your home laundry isn’t quite as clean as you like, the most likely culprit is overloading.  Laundry detergent is formulated to lift dirt and keep it from re-depositing on the clothes.  However, if the machine is over filled, there’s just not enough water to prevent “redep” of soil and dyes.  Take bulky items, like comforters, to a jumbo Laundromat machine (or to us) to make sure they get clean. Don’t ever fill your home washing machine to over 75% capacity — it’s not built to handle it.
