Clean mass air flow?

[Deadduck]

I have a hotwire mass air flow I have had dirty mud water down intake witch has coated the hot wire block and it is causing a hesitation. This sensor is only 1 year old if that I bought a new genuine one just wondering if i have to spend another $350 on a new one or I can clean it some way.
I have tried crc mass air flow cleaner with no luck multiple times I can un plug sensor and car does not hesitate.
