To give burned food the brush off, let a mixture of half water and half vinegar soak in the pan overnight. The burned food comes off easily the next day with a light scouring.
For a professional-style hot-oil treatment, run very hot water over two bath towels, then spin them in the washing machine. Saturate hair with olive or corn oil, and cover your head in foil or plastic wrap. Put the towels around this covering, so that they will not get dirty. Wait for 20 minutes before shampooing and rinsing.
