Guy, I think it was me that suggested foamy shaving cream to clean the upholstery, and it does work! I would check a hidden area first to make sure it doesn't change the color.
Another tip: Old mesh onion bags are great at scrubbing away bugs from the front of the car. Dampen it first (you don't want to dry scrub the paint) and scrub (not too hard) the bugs off. Redampen if necessary.
