quite fancy not being completely lazy this afternoon, so was planning on cleaning up my mongoose system for my s2

its covered in loads of caked and burnt on old oil from where i had catastrophic sump gasket failure so suffice to say its filthy

whats the best products to use to not only get rid of the oil, but also get it nice and shiny and polished looking again?

i have a mop and the usual g3 and 3m finesse it polishing stuff if thats any good?

any advice would be great, and dnt mean to rush any answers but ASAP!!! LOL
