Undiluted white vinegar can be used to both polish and clean your stainless steel flatware. Heat stains can be removed by gently rubbing them with vinegar. To remove streaks from your flatware, gently rub it with olive oil or club soda. Polish dry with a soft cloth.
Reputation: 3896. It really depends upon the school and the type of class. I was able to transfer English (Freshman Comp) and Psychology credits from 35 years ago. However, as I understand it, any science credits usually won't transfer if they are over 5-7 yrs old as so much changes in these fields so rapidly.
Returning to School. College credits are good indefinitely. It's true that technology changes through time and so do many courses. For example, an astronomy class or biotechnology class taught today would be radically different from the same course taught 50 years ago. Fortunately, those differences don't matter in terms of credits.
