Even blowing away relevant data like file structures, cookies that would prove your innocence would typically be considered spoliation or destruction of evidence. Even if the evidence is "Joe is innocent". So you could end up creating a felony out of a situation where you would have ended with nothing. If you did nothing, don't touch anything. If you wipe your already clean device, you've now engaged in real criminality, and will end up creating charged out of thin air for yourself.
