Haha...I almost titled this "how do I clean my car". A two part question............Are there any detailers available that do not have silicons in them. In the past, most of the time, I'd just dust my car with a California duster and finish with Meguires detailer. I now know the detailer is leaving a silicon residue so I have stopped using it in light of a possible repaint coming up in the near future. Second part of the question is how to remove that silicon. Wax and grease remover doesn't. I talked to a ppg rep about it once, and he suggested a bucket of hot water with Dawn dishwashing detergent. He said to do a few square feet at a time, scrubbing briskly, and to dry it off with a handful of paper towels. He cautioned about not reusing the towels after the few square feet. Any better ideas out there? BTW, anybody got a link to that thread 3 or 4 years ago where the poor soul asked how to clean his barn find? I need a good laugh.
