If you buy leafy greens in plastic containers from the store, you will notice condensation always builds up under the lid. All that moisture drips on your greens and soon spoils them.
To help absorb the extra moister, just fold a few non-bleach natural paper towels and lay them on top of the greens and close the lid.
Check the paper towel after a few days. If saturated replace.
If you want to go that extra mile for your greens, empty the container and add paper towels to the bottom of container too. Then add greens back in and lay another set of paper towels on top.
Your greens will thank you by nourishing your baby longer!
