It’s a spectacular day in laundry Olympic history.

Samantha from Southie is attempting the impossible: a quadruple-load wash and full tumble dry — all while protecting the universe.

She dumps the first load in. But what’s this? She pulls out a paper sack of laundry powder from Sweet Grass Farm’s new ecofriendly home care line. It’s concentrated, so she needs only 1/8 cup per cycle. She’s saving the environment — and money, too!

She could pull off 105 loads with that one bag. And look! She’s popped a scented muslin sachet into the dryer. That one bag of sweetness is good for five washes and doubles as a drawer liner. Is that fresh white lilac I smell?

Looks like we’ve found our medal winner.

That was one clean finish.
