Tutorials: Prepping and Cleaning Minis

I'm going to do a series of posts over the next bit asking for or presenting info on various topics on how to do miniatures painting etc. Partly I'm looking for more information because I am looking to improve but also I've found links that I think could be useful. No I'm not going to be giving tutorials, I'm not that good. ;-)

So, if you have an favorite links or articles on the topic of preparing a miniature for painting, let us know. For my part, I actually don't have any links on this topic, and the reason I'm looking for more info is that I know the basics, and am fairly decent at it but I've seen minis that are much better prepared than mine and I'd like to know what tools and tips folks have. My biggest problem is dealing with things like mold lines in tight places and rough surfaces on large expanses (like on cloaks). What tools, tips, tricks, or even special materials do you use?
