okay, so i had the bike serviced yesterday and while the engineer was very pleased with its general grunting, he complained at some length about how utterly filthy it is. generally to clean the bike i would just use wd40 and some hard wiping on all the visible dirty bits. this is time consuming and a pita given that i'm commuting, since it will be dirty again in a couple of days, and i can't be bothered to do this more than once every couple of months. but i'm more concerned at the minute with all the bits i can't easily get to with a rag, since these parts won't have been cleaned for at least 7 years. the engineer said to spray shiteloads of some kind of degreasant all over everything, until the grime starts sliding off by itself in a gooey slime, and then jetwashing. problem with this approach: i haven't got a jetwash and don't know where one is that i could use, and even if i did i know that there are some parts of the bike that you mustn't point the jet at, but don't know exactly which bits these are. so, perhaps the font can offer some useful advice, ridicule, or perhaps even an offer to do it for me for a reasonable sum of money.
