Did you just spray diesel fuel on the bottom of the car and let it sit over night? Would you be able to power wash it off without using a scraper ? I was gonna doing the same with my car to get it cleaned up.

Looks great I would clean it and leave it alone. If you get a power washer with hot water those work very well. The plastic scrapers is great to use for the larger undercoating and to get the rest I would use the something like a DX 330

No, you need a scrapper. It is gooy and easy to get off in some places but in others it is baked on and needs to be softened with the de-greaser and then scrapped off. Power washer would be very very messy and may mess up the paint on the outside of the car.

I used diesel the first go around but GUNK Heavy Duty Engine Degreaser works the best.
