I have been trying several ways to clean my dutch ovens. I want to find the easiest and most effective way to do it. I have read several D.O. cookbooks and spent a lot of time on the Internet. The last few days I have been using a large scrap of burlap to scrape out my ovens. This actually works pretty well. I was surprised. But it has a definite down side--it leaves little burlap hairs in my ovens that are hard to get out. To be honest, it grosses me out a little bit so I will save this method for the really stuck on stuff.
I have also tried boiling out my ovens. This works well too, but I don't like having to take the extra time to heat more coals and I have been to lazy to get my camp stove out every day. I will save this method for the stuck on stuff as well.
Really, the fastest and easiest way I have tried so far is the plastic scraper and the vinegar/water mixture. If I run across other methods I will review them as well.
