OK.. the question that most I think would like to know. What is the best way to keep your engine bay nice and clean on the 92-96 with the opti? I myself just use compressed air  (NO WATER) and a nice clean cloth but doesn't get the results as some others here. Make no mistake, mines clean just not nice and sparkling clean like I have seen other 92-96 opti cars.
Thanks in advance

  I am going to try that hopefuly this weekend, will repost a response.

I have used S-100 motorcycle wash you have to rinse the thing GOOD  it dose wonders on alum.  & plastic     but you gotta rinse it  then blow it dry

Sounds like you know not to spray water on an LT-1.  I wipe down the engine bay with Armor All, or similar product.

First clean it every time you wash the car, I cover the motor with a canvas cover and wash the rest with degreaser and a garden hose than blow dry with air. Go back and retreat with low gloss tire shine on a sponge. Lastly clean up the motor with damp cloth and wax.
