I wash my bikes with plain water, spray on 409 type stuff or just soapy water. I sometimes finish up the CF bike with Armoral, 303 or similar type of protectant, or pledge. On the ti bikes, I might use the same things or stainless steel cleaner like Weiman's.
But I rarely clean a bike other than spraying it down in the yard to get off the obvious dirt ;or quickly cleaning it with some 409 type stuff on a rag.
