There are some very toxic substances on that list, the production of which generated substantial amounts of pollution.
Soaking in toxic chemicals, rinsing, baking, etc. -- wouldn't a small amount of petroleum solvent applied to the chain (a $10 part) on the bike be simpler and cleaner for both the chain and environment?
