Sliced Bread - Series 17: Laundry Detergents
Summary
Host Greg Foote and chemistry expert Professor Stephen Abbott investigate laundry detergents to determine if they are the best thing since sliced bread or marketing BS.

The episode compares pods, liquids, and powders, highlighting that proper dosing and rinsing matter more than format, while eco-brands often sacrifice cleaning power.
