I fashioned a cold smoke generator out of a mesh colander after seeing the idea somewhere else on the site. I'd like to test it out but I dont want to waste what little apple dust I have right now, so I thought I could just load it with pine dust from my shop and put it in a cardboard box outside to see if it works properly first. This should be ok right? I cant imagine much creosote or whatnot building up on it, though it is too flimsy to take a wire brush to. What say you all?
