Not sure if trap will improve, I'm just worried about shaking while idle...

If it is heat discollored, this method won't help make it clear, but if it is DIRTY on the inside, this worked wonders...

When I got this tank, it looked white, but was dirty on the inside, like it had been on a car that mixed oil and coolant... you know the scum inside the tank...

I wonder if this would work on cleaning out all the crap that gets built up in the brake fluid resevoir over time...

so i wonder why coffee grinds work better than any other abrasive. i'd imagine sand would have done the same thing...

is this like something for a Materials Science engineer to study? hehe

Very cool, I bought a slightly used one and had the same issue, tried most of the things you did and still was disapointed. I will try this next time I have my tank off.

I had similar results using pool sand and either simple green or super clean, I honestly do not recall at this point. The solution removed all of the internal buildup and the tank looked way better than before, but was still yellow.

I tried the coffee grounds. Pretty strenuous effort. Multiple flush and grind and shake and simple green and lots of water and grounds and shaking. Oh - and did I mention that I did a lot of shaking. Little improvement in my case. My car is getting some oil in the water (yeah, I know). The oil floats on the edge of the water level in the overflow. The oil has accumulated making it very hard to see the water level - since it float at the water level - dah. Anyway, the coffee may have done a little. I guess the proof will be when I refill it and try to see the water. But there is still a lot of black accumulation on the water line. I think I cleaned my old tank pretty well with detergent based cleaner and water. But that car was not leaking oil into the water. Guess I need to do the head gasket and look for another tank. Oh, by the way I was using New Orlean Chicory coffee, trying to get rid of it. Maybe it's not any good for cleaning overflow tanks either.

I had pretty good luck with Polident (the denture cleaner and before you ask, no, I don't have dentures!) but the coffee is a new one and it looks like you got better results than I did. Awesome find!
