Though you could technically use any degreaser on your bike's chain, it's advisable to use one specifically designed for bike chains for the best results. Bike-specific degreasers are engineered to efficiently dissolve the grease and grime typically found on bike chains, without causing harm to the metal or the O-rings within the chain links. Contrarily, general or industrial degreasers may be excessively harsh for bike chains, potentially stripping away vital lubricants, damaging the metal, and harming the rubber O-rings. Some degreasers may leave a residue that attracts more dirt and grime, resulting in accelerated wear and tear on your chain. Also, consider the environmental implications. Many bike-specific degreasers are biodegradable and less environmentally damaging than general degreasers.
