I thought my aluminum radiator, (and heads) suffered from deposits, so I started to look for a way to flush the system. I found an article from a MBnz technical reference and did this:
mixed 3 pounds of citric acid in 3 gallons of water to yield an approximate 10% solution, drained and refilled the system and ran the car to warmup. I could tell, from skin contact, that the solutionj was not nasty, but definitely acidic, as felt by my skin.
After a complete rinse, the inside of the radiator looked much better and I will know if my overheat is solved soon. Seems the clowns at Sevens Only racing 'forgot' to reinstall the Robert Shaw 180* thermostat I had installed to solve the prior overheating issue.

Sources for the powdered citric acid I found included a b=Home Beer brewing store and a 'whole foods' type market. I'd heard nothing good about the available flushing products at the auto parts stores, BTW, and feel that citric acid is quite safe to use and for nature.
Interesting, a comment from the 'beer guy' who said he used it for cleaning his tools of rust, etc.
