Tip for the exhaust/rims: theres a product called "Autosol", comes in a black tube with gold writing... Pretty sure you'd be able to get it over in UK, as its a German product... Anyway, its a metal polish and cleans up tarnished/aged metal surfaces perfectly... My exhaust was rusted and tarnished more so than yours and I got it back to its shiny chrome finish using this product... I also used it on my sister's car which had lots of brake dust build up that wasnt coming off with anything else... Came up good as new...
Thought you might wana look into that
