Care Instructions

We recommend soaking your Mint absorbent undies in cold water before washing them. If after a few months, you want to freshen them up, soak them in white vinegar for 10 minutes before the wash. Do not use a dryer, as high temperatures can damage the leakproof layer. Line dry only.
