Slate’s Green Lantern column (personally, never heard about it until today) answered some reader’s question about washing containers before throwing them in the recycling bin.  I never bothered, but I know my wife has done it on occasion when she feels like it.  Reading the article, Clean Jar, Clean Conscience, it turns out, it is not necessary, which doesn’t change my life at all.  There’s also some interesting tidbits about the recycling process as a whole, so it’s worth a quick read, if you are interested.
