I have stripped the bike and Iam trying to clean the swingarm (which has clearly never been by the previous scumbag owner!). It has a layer of oil, dirt etc that I cannot shift, all I seem to be doing is spreading it around. I have tried several products and methods but it still feels sticky and looks dirty (er..)

I need a product, method that will shift the gunk? Any ideas?

I considered the dishwasher?
(thats a joke)
