I'm about to put our Urban Elite on Ebay and want to give it a good clean first. Ds has been sitting in the Kaiser for months and I hadn't realised just how much crap had accumulated under the liner The hood also needs a damn good clean, but doesn't seem to come off the frame. The Elite has the canvas fabric, so do you think it would be OK to go in the machine? Or should I stick to giving it a wipe with soapy water? Any advice appreciated
