I bought a small 99p UV torch from ebay the other day. I wandered around the kitchen at night and showed the wife all the dirt with it. I then went with my bruised ear down to the garage where the highly polished red 848 was sitting on the bike lift. Without switching the garage lights on I shone the UV torch at the bike and nearly had a heart attack! All of the spots of fly blood and the smear marks from polishing were there shining bright white at me. At least it kept me out of the wifes way while I cleaned the 848 again properly. When the wife calms down I am going to use the torch on her bike while she is watching. I might end up with another sore ear or having to clean hers, I doubt that she is going to thank me for pointing it out. Why don't women like technology.
