Just finished detailing my 05 with menzerna and a coat of Collinite 845 (I am very impressed with this wax). I was wondering if there is any good OTC soap that will not strip the wax? I know most claim they won't, but it just doesn't seem that way from my personal experience. Also any suggestions for cleaning the engine compartment? I am a little nervous about spraying it down even if i do cover certain components with plastic. Thanks.:-D
