Dish detergent to clean oil sludge out of the cooling system?

Removes stains from clothes in laundry.

Cleans brake dust off your wheels easily.

Repels insects.

Safe to clean tools with.

Can be frozen as a soft ice pack.

Prevents poison ivy from spreading.

Cleans car leaks from the driveway.

Lubricates door hinges.

De-ices sidewalks.

Removes permanent ink.

Grill cleaner.

Safe on laminate floors.

I could go on... BEST THING EVER.

And I have a friend who works in testing at P&G, Dawn Platinum and variations are really the same formula. Buy traditional blue dawn for the best results.

 

And- - - - - - -It tastes really great!
One thing Dawn is NOT good for is dishwashers! I was operating HUA one night and filled the soap dispenser with Dawn rather than Cascade! OMG WHAT A DISASTER!
Note: If any one else here is as senile as I am, and does this, some Downey Fabric Softner in the dishwasher goes a long ways towards getting rid of the suds. After you get everything else cleaned up of course. . .

 

I know a way to remove all traces of the oil, but I can't tell you. It's an ancient Chinese secret
