The Park Tool Bio ChainBrite CB-4 degreaser is 100% bio-degradable. The Bio Chainbrite CB-4 makes your chain, cassette, and chainrings look like new again in no time at all. Aluminium, plastic, or rubber won't be affected. It can be used purely, so no water dilution required. If needed, use a rag or brush to polish your components.
