yah, i'm on the edgy side of thrifty...
Here's the one that I happened across. young feller sprucing up his car.
It doesn't start out with the essentials, but his vid for that can probably be rooted out fairly quickly.
with the chems in solution and a little juice, he seems to be doing the work in minutes! I'm sure there's a bit more to it, but it's basically simple to accomplish.
I'm off on a tangent now, to build a small scrap metal foundry and try a bit of lost wax investment casting... fun stuff!
