Here’s a frugal way to “pre-soak” your laundry if your washer empties into a sink or utility tub. When washing a load of clothes, place a bucket under the hose that goes into your sink. When it’s full, add the items in need of “pre-soaking” into the bucket and set aside.
There’s no need to add any laundry products because the detergent is already in the water. When it’s time to launder the items, empty the bucket into the washer.
