Isopropyl rubbing alcohol, especially in a concentration of 70%, is known for its rapid evaporation. If it gets on dishes and silverware and dries before being rinsed or washed, it is unlikely to be absorbed into the dishes or pose a significant risk to health.
Isopropyl alcohol evaporates quickly, leaving behind minimal residue. If the alcohol has completely evaporated and the dishes have not been used in the meantime, the potential for any residual alcohol to transfer to food or beverages is extremely low.
However, it is generally recommended to wash dishes and silverware promptly after they come into contact with any substances that are not intended for food contact, including rubbing alcohol. Washing with warm water and dish soap will help remove any potential residue and ensure the dishes are clean and safe to use.
If you're concerned about the safety of your dishes and silverware, you can give them a thorough wash with warm water and dish soap to alleviate any residual concerns. It's always a good practice to wash utensils before using them, especially if they have been in storage for an extended period of time.
