Grump you are great. I will have to try that one.
I use kerosene (Brit. paraffin) with old tooth brush and paper shop towels, that can be thrown away, to clean the chain. I do this at least every 500 miles. One should never use a power washer on the chain. The chain has factory installed lube and seals in the rollers. The power washer could remove this lube and you will never be able to replace it. To lube the chain I use Bel Ray chain lube. It is white so it's easy to see your coverage.
