Spouse and I have a discussion on what to do after you pour a sauce out of a glass bottle. I do nothing but my wife takes her finger and wipes the excess from the bottle before she puts the lid back on. I think touching the food is disgusting and she thinks leaving it there to gum up the lid is disgusting. What do people do?
I clean it off. I feel this helps prevent spoilage as the lid will have a better seal on a clean rim than a dirty one.
