Radiator Over Flow Tank

[LOW AND BLOWN]

Did some searching with little success, what are you guys using to get the dark stains out of the overflow tank?

This is a little thread jack.

I have not done any stain removing, but I did add a hose to the over flow, so when, it does overflow, it does not trash my engine compartment.

I just did a custom aluminum one looks better and no stains

Ok thanks, I finally just used a bristle brush like what you would use to clean baby bottles

The best trick is to toss a half cup of rice in there, a few second of brake cleaner spray to get some fluid in there to swish around, maybe a little concentrated cleaner for fluid aswell. Shake it real good. Will look BRAND NEW, promise I do it quite a bit, gets rid of everything internally
