The inside of rims. . .

There are parts of a car you seldom see.
Recently, I had my rear tires off the time machine and a friend suggested it was a great chance to scrub them puppies.
What a golden opportunity!
So, with several choice weapons, including a screwdriver for scraping clumps of tar-goo, and brillo pads and rags, etc. I set to a-scrubbin.
I wondered, as I toiled, if perhaps I was the very first person to ever take the time to do such a thing to these nasty bits. It was like an archeological site. A time machine has a way of collecting bits from all our previous journeys, and from the looks of it, several layers more from the future!
I also wondered if professionals have a special tire-rim bathing tub, similar to what pet groomers use, where you don't have to bend down so far. But discomfort was displaced by satisfaction as each pass of the hose revealed a rather pretty inner tire! The photo is a kind of 'before and after', as I complete the right wheel, but not having started on the other.
Note to self: Move face away from objects before spraying with hose. You can see how good it looks *after* the hose is turned off, thus avoiding a face-full of splashback.
