Would this work?

I don't think that one will work. It calls for a 4000 PSI I think. But you can always rent one.
That's a great idea!! I found one on Amazon that uses 1000-2500 psi but it has terrible reviews so I do think I will waste my money on that one! I an gonna do some research and see what the cost of renting one would be. I'm pretty sure my neighbor has one he may let me borrow it.
