Can You Trust That Used Plastic Container?

Ever tried to buy a sturdy plastic container for your garage, only to hit B2B gatekeepers and pallet minimums? The second-hand market seems like the obvious answer — but it's a minefield of mystery chemicals, vague sellers, and containers with hidden histories. This episode unpacks the materials science of HDPE plastic, explaining why some chemicals penetrate deep into the polymer matrix and how the sniff test can fail you completely. We break down which industries are safe bets for sourcing, how to read UN markings, and why bleach can actually make contamination worse. If you've ever wondered whether that "basically new" tote on Facebook Marketplace is safe for storing clothes or kids' toys, this episode is for you.
