Cleaning Coolant Tank

I'm doing a major cleaning of my car in a couple weekends. Trans fluid, filter, plugs, wires, fuel filter, oil pan and gasket, thermostat, and lastly a coolant flush and switch to Yellow Peak :D BUT, my coolant tank is dirty, like really bad. I cannot scrub the areas affected, so while I am doing the other work, is there anything, any solution, I could have the tank in to eat away at that dexcool gunk?
 


I dumped a bunch if mean green in it and shook it up and let it sit overnight and it helped but didn't clean it totally. Bleach might be the ticket
 
Took my tank off, a water hose flush the inside, soaked it in simple green after a brake cleaner scrub down, lol, looked like NEW.

It looked new that is... until my axle started throwing greased, seems it'll need a new cleaning again soon.

:D
 
Bought a new replacement tank for our '04 GP from the Chevy dealer today for $29. It was cheaper than a used one from one of the local wrecking yards.
 
Some of the junkyards are ridiculously high.
And i tried a hose and purple power. Not a lot better. But that was a while ago.
 


Dawn, very hot water, shake violently... rinse and repeat

I did it in the bathtub though, so the nastiness would go down the drain and not into the ground... call me a tree hugging hippie but I dont want ethylene glycol or Dawn in my area's water supply or my soil.
 
Take tank off, put your favorite cleaning solution in, and then put some small nuts and flat washers in so when you shake the tank around the nuts & washers will scrub away. If you're worred about getting all of them back out, count them before and after.
 


I did brake cleaner and let it soak the flushed with red hot water (boiled on the stove wear gloves so you don't burn your hands) Let dry reapeat.
