While camping in remote lands, you need to be a bit creative while washing your outdoor cookware. First, wash your pans and pots with biodegradable soap and water. After a good scrubbing, strain the water and wash off food particles along with it. Then add warm water to sanitize it once more. In case you have forgotten to bring soaps with you, sand or snow scrub will be sufficient as well. But, do not use sand if your cookware is non-stick. In a situation like this, just boiling water will do the sanitization.
