This is something we’ve been meaning to do for a long time: power wash the chassis of our Miata. It’s not strictly necessary, but when working underneath the car, it’s more pleasant when we can come out without incredible layers of dirt and grime on our bodies. Both our previous races featured plenty of rain, which means plenty of track grime splashing up onto everything underneath.
Power washing is quick and easy. A jack, a couple of stands, and maybe 10 minutes’ worth of gas in the machine.
We’re doing this and lots of other little bits of maintenance as we prepare for the 24 Hours of LeMons Humidi TT at Sebring International Raceway. This is the first time the event will tackle Sebring, but we’re sure it’ll be just as riotous a time as it is everywhere else they go.

I made myself a little underside powerwashing rig:
Works pretty good. With a non-lowered vehicle, it fits right underneath without the need to jack it up. And since it sprays straight up, it can hit areas that would be tough to hit without putting the car on a lift. Incidentally, I coated the wood with that Rust-O-Leum "Never Wet" stuff. So far, so good.

Sweet! Where can I get the fittings for the pressure washer connections? I have the same ones on Dewalt washer.
Dude that is awesome. More pics of the fittings. I never thought about doing something like this but that's just way cool.

Pressure washers typically use straight-through fittings like the Parker ST series.

Build thread!
I wonder if you could "T" the pipe at the end instead of that fitting and drill a bunch of holes in it if you needed it to be much lower profile for a lowered vehicle.
Nice. I was looking at something like this for several hundred bucks....
But then I found this for around $40.00

Wow! Impressive powerwashing rig you have there!
