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...

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!
