True copper will change color at times, even when it is not being used. There are many solutions for cleaning copper.
- If there are areas of discoloration (which is common when heat is applied to copper), simply clean them away with a copper cleaner.
- If no cleaner is available, cut a lemon in half, cover it with salt and rub it along the surface. This is an easy way to make a simple, homemade cleaner for copper.
- Another homemade copper cleaner can be made by combining equal parts of salt, white vinegar, and flour.
- After applying any cleaner – commercial or homemade:
- Wash the pot in hot, soapy water.
- Buff with a soft cloth to make it shine.
