Cleaning the gearbox

As I'm removing stuff, I'm trying to clean it up. Hopefully this will make it a bit of a cleaner and easier job when it comes to putting things back together. The gearbox was pretty minging dirty and it took a bit of shifting with a wire-brush so thought I'd try using some Gunk Engine Degreaser. I mixed it 1:1 with paraffin just to make it last a little longer, then used a jet-washer to rinse it all off. The paraffin left a oily residue so used a light brush of neat gunk to clean this and then jet-washed it off. I'm pretty pleased with the result.
