Most things you can wash as you usually would, with hot soapy water and a hot rinse. Things with or that will have alcohol in them are basically getting sterilized.
You don’t throw out your containers, droppers bottles etc.. after you used them. That would be a waste of money. You wash and reuse them again, it’s that simple.
O swish some rubbing alcohol around in my containers, then wave them vigorously in the air until the alcohol is all evaporated. If I had a dishwasher i wouldn’t bother with alcohol.
