I read a past line of Q's on injecting water for decarbonization. I assume that the antifreze mix that is in the cold start assist system would work as well?
My question is... what if you filled that chamber with windshield washer fluid, wondering if the methanol/water mix would clean better than antifreze.
I just need something to put in there that won't freeze.

Any suggestions for fluids?

methanol is a bit unstable i think....

I doubt the methanol would make any difference. It burns, right?
The water tick is done with the enigne running, and so the carbon is removed from steam. Methanol would make no signifcant difference while running.
Water, mmo, ATF, all things that don't burn so hot are what removes carbon the best. So I doubt adding something that's already present in fuel is gonna make any difference.

It seems you would only want to do this to motors with not many miles on them. I mean H2O doesn't dissolve the carbon flakes so it seems a high mile motor with alot of carbon would only be damaged when the flakes break loose and try to pass thru.

It doesn't blast flakes loose per se... if the carbon was scaly enough to break off in flakes or chunks, it would do that just in the course of driving the car.

The water flashing to steam "eats away" at the carbon. It's more of a dissolving action than a blasting-free action.

well eat away / burn off right? My guess is that the steam produced transfers heat better so it'll heat up surfaces more. So anything that produces a hot vapor from liquid should be fine.
I was just wondering if mathanol/water mix would cause a 'thermal event' to occur for any reason.
