We have so much dirty laundry; I’m not sure how three people could dirty so much laundry. I average a load of towels a day, and about 9 loads of assorted clothes per week. I can’t keep up with daily laundry, so I’ve been known to do several loads over the course of a few hours and pile them onto my folding table. I normally buy the economy size detergent and watch it quickly disappear. I was happy to discover a new laundry detergent (at least new to me), method laundry detergent doesn’t disappear as quickly as the rest.
