Unfourtunately, when I started the WH hobby and broke this hobby knife. None of my friends whom I currently play with thought enough to give me any assembly tips, and I'm not likely to go online to figure out how to clean models. So I learned by trial and error.
Eh, people ask all kinds of questions, many a lot sillier than how to clean models. Everything you do you must learn, nothing is natural. Hell you even had to learn how to walk, let alone hold a knife or paint brush. There is no shame in asking simple questions.
Maybe the other pathetic races need to learn to walk, but we lizardmen can from the second we leave the spawning pool... ALL HAIL THE OLD ONES!!!!
