So, dumb question here... This weekend I moved two tons of pellets into my basement. I only had one bag split on me and it spilled about a quarter of the contents on the basement floor. I swept them off the floor and along with the pellets came the usual basement floor stuff like concrete dust and dead spiders. Can I use these "dirty" pellets in my Quad? I guess the question is, how fussy is a stove about a little sandy dust and bugs?
