Ipone products are some of the best I've come across for degreasing..etc..all developed for motorbikes. Cheers Grant
Motorcycle chain cleaner is indeed a foolish rip-off. Paraffin or Kerosene as we call it on this side of the pond, is inexpensive and the base ingredient for most chain cleaning products. I still have some in the garage but the problem with it is the smell. Try Simple Green de-greaser. It's not quite as strong but you can use it everywhere such as rims and plastics. It's bio-degradable and wont harm the chain's o-rings. It's also cheap and smells great. I'll never go back to anything else.
Parrafin. Its cheap. And wifeys old suede brush. Well, its old now but it wasnt when I stole it. No, I havent seen it dear. You sure you put it there? Nope, never seen it.
If the bike is stored in a garage mix 2 tablespoons of molten chocolate with 2 tablespoons of animal fat and a tea spoon of cornflour. Stir briskly and apply liberally to the chain. Mice love the mix and will break their teeth down to the gums trying to eat it thereby saving any damage to your bike or household wiring. Leaves a nice finish on the chain.
