Coolant system flush

[Cya]

I've flushed it three times now and im still getting brown fluid any suggestions?

Oh i've tried the Prestone Cleaner, Prestone Flush and hell and even tried the Simple green.

Did you use Prestone Heavy Duty Cleaner? It's a two part powdered product that includes a neutralizer. If not get some oxalic acid from a chemical supply or ebay, it's the same chemical used in the Prestone. Neutralize with sodium carbonate (soda ash). If this doesn't clean it out, nothing will. Make sure you completely flush it out of the system.

I'll be looking for the Heavy Duty Cleaner tomorrow and I'll let you know the results. Thanks dude.
