How do you do cheap laundry? That is a very good question and I wish that I knew the answer. I try to extend the period of time I can go between doing loads by changing out of clothes right after I wear them. If I have only had my slacks on for a few hours, I hang them back up and put them in the closet again. Now, I never do this with any sort of clothing that is stained or has the appearance that it has been worn before. However, by hanging up clothes again and occasionally spraying Fabreeze into the closet, I can go at least three weeks without having to do laundry. I cut down on the number of loads too, which means that when all is said and done, I save around $12-15 a laundry cycle.
