really, get a flat blade scrapper and get the worst of it. then go to the coin opp car wash. spray the degreaser on, let it sit for a minute, then use the high pressure rinse. bring a floor jack and get it sitting up high in the front. or some ramps. and do under the hood too. itll look way better for a little work and some quarters.
best way to tackle that is go buy some purple power, like 10 bucks a gallon. put it in a spray bottle... spray everything under the truck thats dirty, let it soak. coat it again, rinse and repeat untill clean.. dont even need to scrub really...
yeah. true. but i try to get the worst off so it doesnt fly into my face or all over as much. less to blow away is less that gets everywhere. and the spray places have grease/oil traps to protect the local water system.
