ELT gets to the bottom of a familiar aroma -- thrift store smell. Why do thrift shops all smell the same? Plus, is washing your clothes better than freezing them? ELT investigates listener cleanspiracies with expert cleaner Jolie Kerr. Guest: Jolie Kerr, writer and host of Ask a Clean Person. Thanks to callers Theresa, Rachel, Jeremiah, Nikki, Vicki, Mark, Juliana, Ben and all the listeners who called in with cleanspiracies.
