After making yogurt in your MEC pot, you can let it stay for as long as it’s finished. While cleaning the pot for the next batch you may see some residue that’s not coming off easily. Here is what you can do to clean your pot thoroughly:
Apply some warm water on the spot that’s hard to clean, rub with hands and let it sit for 5 minutes, and scrap off with a metal spoon.
Swooshing just a little water around the pot, pouring it out and then pouring the milk in, will also reduce the sticking.
