I remember my mom making waffles on a waffle iron that was so freaking old and perfectly seasoned....one day the German woman across the street asked if we had on she could borrow.....next day shr brought it back and she must have worked for hours with steel wool etc to get it looking like new !
My mom was polite and told her that she had removed soooo many years of seasoning but she would just do it again
Never loaned out anything like that again.
