In MY opinion, the single bestest evAr "invention" I've ever made
Yes, I am a freak, this is Episode 19865372 of that, you all know the drill by now LOL.
I have wrestled with this issue for awhile. My grandparents first allowed me to borrow for the winter the pressure washer they bought a couple years ago, since they'd have no use for it during winters. This was a great step, now I could wash my car and mom's cars with hot high pressure water. BUT, a straight wand, makes it tough to really be sure you've gotten all of the underside. Especially the fender lips, and on my mom's ExploDer there are stupid plastic covers/trim all over everything, including all of the wheel wells. It is impossible to directly spray them, especially the py spot welded seams all rear fenders have.
SO finally the solution has been found. Pieces of pipe lying around and a hose barb fitting. I crunched the end of the barb in a vise! That's it and BAM a nice fan of water and plenty of pressure, it looks exactly like what you see come up out of the floor nozzles in a touchless carwash. The wand of the washer happens to have a standard NPT I suppose, thread to it, so this piece just fits right on. I can now angle around and get evvvvvverything, as well as just get the floor real easy by sitting it on the ground, sliding it back and forth and moving down the length of the car.
This literally destroys a huge amount of stress from my being during the winter from now forward LOL. All of our vehicles in this household are nice and rust-free, I intend to keep it that way. I will fight the salt forevermore.
