Vintage GE Waffle Iron

This is a vintage General Electric model # 119W8 115volt waffle iron. It is in need of a good cleaning, I haven't touched it in years. I did not clean it before selling because I do not know much about it and do not want to clean it with the wrong cleaner. I pluged it in and it did not get hot, I do not know if it is the plug or not. It was my grandmothers. Please e-mail me with any questions. Good Luck.
