Hello fellow skoolies. I'm not sure if this was already brought up in another thread but I have a 2000 flat-nose front engine Bluebird, 5.9 cummings engine and Allison transmission. I have a lot of dirt/grease/general nastiness on my engine and underneath my bus so I was trying to detail my engine and underbody with a degreaser (purple power) and a pressure washer.
Any tips on major do's and don'ts? there weren't a lot of videos online detailing this on a school bus specifically so I wanted to bring it here and hopefully avoid foolish mistakes.
Of course I know to cover electrical with aluminum foil but please let me know of any easily forgettable spots to cover what other steps should I take to ensure a smooth process and properly working bus afterwards.
