Good old Cascade doest plenty. I wouldn't add anything else. Just make sure the Cascade is fully dissolved before putting it in the system. Then flush flush flush

How is Cascade at getting rust out? I can see it doing a good job at degreasing and possibly de-mineralizing, but I've got an issue with rust in my cooling system.

What's the procedure for using Cascade? I get the predilute part. OK. How long do you run this with the cooling system up to temperature?

I've used Prestone Super Flush as directed. It did nothing to the coating of rust I see in my coolant tank or radiator hoses. I can wipe the rust easily with my finger, but I can't get my finger up 12" of hose, let alone through the entire block. Reminds me of the joke about the Proctologist who rebuilt an engine for a shop class - got extra credit for doing it through the tailpipe.

Thanks,

Also, I have to add, I'm very cautious about the idea of using Cascade on the cooling system. Dishwasher Detergent is very caustic. Aluminum radiators and engines (my 300M has aluminum block and heads) aren't anodized to protect against such harsh chemicals. If the Cascade does to my engine what it does to the aluminum coating on the bottom of my pots and pans, I don't want it anywhere near my cooling system.

To make matters worse, the formulation of Cascade with Dawn was changed for a 1 July 2010 mandate to eliminate phosphates. There have been many complaints about the detergent leaving a white residue and discoloring aluminum cookware. Is the solution worse than the cure? Perhaps so!

Unless Cascade is used in a much milder dilution than used in automatic dishwashers, I'm afraid this is a very bad idea.

Proctor and Gamble's suggestion to consumers is to use Vinegar to clean the black from the aluminum, and if that doesn't work, they have been known to pay damages. I'm sure that wouldn't include a new motor! But perhaps a (white) vinegar solution is an alternative to cleaning and descaling the cooling system. Chemically, this is similar to the other acidic treatments that have been suggested. I just worry that acids also act as electrolytes for galvanic corrosion, and I know the rust in my system is from galvanic corrosion between the aluminum engine and the cast iron water pump impeller and hard coolant lines (such as under the intake manifold, and to/from the heater core).

Timing (long enough to descale and derust, short enough not to promote more galvanic corrosion) must be key to using acids.

Warmest regards,

I recently did the Cascade flush. It left behind no rust at all that was on any metal part, but it could not knock that crud out of my rubber hoses. I have since had the cooling system apart, and saw no sign of any damage to the aluminum pieces.
