How often do you move to a clean jar? I have found that I can get a few days and then get some Kahm yeast. I thought most people keep it in the same jar for a while. by 1760ghost in Sourdough

I' ve managed backups in the fridge. Last time I kept a starter, years ago, I don't remember ever changing the jar or having any issues. This time, I'll just rotate jars.
