A wetted rag soaked in Hammerite brush cleaner worked wonders on my swingarm yesterday when i had the back wheel off. White spirit is also a good degreaser, also Gunk engine cleaner.Yesterday, took the 9'er to the local jetwash to clean the engine and swinger. Engine looks a bit cleaner but it didn't touch the crap on the swinger. Oiled and adjusted the drivechain and went for a pootle in the lovely sunshine.
If you want to go solvent free then a dishwasher tablet dissolved in a cup or less of hot water and repeated applications is quite good (use rubber gloves)
