Nalgene bottles seem like they'd be pretty dandy for cleaning chains in. Add solvent and chain, shake like hell, empty.

Since I don't have access to the actual journals, all I could read was abstracts and all I could glean from them is the jury is still out.

Kevin (SG's brother) is 3/4 right about not heating stuff in plastic containers. I did a quick scan of the net and found government agencies in the UK, Singapore and the US saying that single-use plastic and polystyrene containers are not suitable for heating/reheating food.

It may be my cantankerous upbringing but I don't trust the media to give me an unbiased view of what is going on. The popular science magazines (Sci Am, New Scientist, Discover, etc.) do a good job because if they don't their readers will pillory them. The rest are just trying to sell advertising by hawking the horror of the day.
