Cleaning your overflow resavoir: a "mak's bored so he did this" 'how to'.
Ok...got bored earlier and started tinkering with my car. I checked my overflow and I realized that I always have to take the cap off to see where the coolant is...that's kinna sad because I thought the plastic was supposed to be clear enough that you could see it from the outside...but who knows?
Anyways...I started with this:
...and...
...and...
Very nasty, needless to say. To start, I filled my sink up with hot water and a couple cups of bleach. I filled the res up and let it soak in the sink for about 20 minutes or so with a rock on it (plastic floats...go figure). Afterwards I drained it and gave it a liberal coating of comet and went at the outside with a wire brush. All I had was a small wire brush..I'd suggest using something a bit more friendly like some fine steel wool. after about 15 minutes I had most of the embedded soot off the outside. Came out fairly decent:
But who cares? It's easy to clean the outside, right? Well, the inside stumped me. I could get a brush to all the surfaces...soaking in various solvents didn't help...the high-pressure hot water sprayer didn't even budge any of it. So finally I got an idea...out in our mill here at work, they drop corn through this metal grate. This grate is made out of old 3.5" drill stem...which is very coroded by the time we get it...however, it's quite polished now. So I tossed a handful of corn in the res and shook it like a polaroid peekshoor. After mediocre results I threw in some rocks and repeated. After about 20 minutes of vigourous shaking it came out like this:
