Squeeze out some of the lemon juice as you scrub, and add more salt as it starts to dissolve. The acidity of the juice and the abrasive texture of the salt will work together to remove tough stains. This approach can also work on plastic cutting boards. However, the lemon juice and baking soda process recommended for use on plastic food containers may produce better results.

This method works especially well on tomato-based residue and spice stains.

Once the food residue has loosened up, remove the bowl and wipe down all of the microwave’s inside surfaces, including the door and turntable, with a cleaning cloth or sponge. To dislodge any stuck-on pieces, dip a corner of the cleaning cloth or sponge into the lemon-water and use the damp corner to scrub away the food residue. Be careful when removing the bowl and the turntable as they will be hot! Use oven mitts, a potholder, or a towel to protect your hands. You can use a similar technique to clean your oven. Fill a baking dish with water and lemon juice, then leave it in the oven on 250 °F (121 °C) for 30 minutes so that the steam can loosen up grimy buildup. Wipe the interior of the oven with a damp sponge after it cools. [5] X Research source

This works well for copper pots as well as decorative copper objects. It can also clean stainless steel pots and pans.
