What minimum pressure rating would you recommend for pressure washing a greasy old truck engine and frame? I would especially like to hear from people who have done this themselves.
The reason I'm asking, is that I tend to go a bit overboard with things like this, haha!
I plan to use a pressure washer to remove years of grease from my engine. I also want to clean the rear axle and frame. I think a garden hose and a stiff brush will not do the job well enough.
Rental units usually have around 2400 psi or higher. Cost ranges from $40 to $60 for 3 or 4 hours. The Walmart and Lowes units do not have good reviews, so I doubt I will purchase a unit.
