I brush mine out, thrown them on the lawn and hose them down with the garden hose. After they dry in the garage I throw them in the washer.
My wife has flower pots she has been using for decades. She clones and doesn’t even know what the hel cloning is. Likewise my outdoor grower friends, their biggest challenge is keeping the deer away from their plants.
I grew up on a hobby farm and worked on a truck farm in the mid sixties. I’m partial to being more of a gardener than chemist/programmer. These are plants that survived tens of thousands of years outdoors.
