This is considering a properly working water injection system, in which the water nozzles are not damaged (and damage is often done by the methanol, not the water) and the spray comes out the way it's meant to, as a pressurized mist, not as big fat water droplets. This mist flashes into vapor very, very quickly when it meets the hot intake charge, and anything that survives in mist form by the time it comes to the (hot) intake manifold and combustion chamber should evaporate when it gets there.

Some of that "mist" sounds a lot like "steam" which is extremely damaging to metal over time. Sounds more like something you'd use on a very temporary basis just to knock the carbon deposits out of your combustion chambers, rather than something safe for long term use.
