Haven't you ever heard/seen that electronics and water are not the best of friends? Such a situation is incomprehensible to me, because I never have any liquids near my computer or any other electronics.
It is security wise. We should stop doing things belong to our childhood or teenager hood.
Eating and drinking when we are working with a computer, a laptop are simply unwise and it's very risky for physical damages on digital devices. Even we turn off our computer or laptop, like you said we should not put any water, liquid around our devices.
I recommend that you seek professional help from people who are engaged in professional data recovery, and considering that you have very sensitive data, you can ask to be present during the procedure (some offer this option). Of course, as some have already mentioned, you should first calculate whether it is worth saving the data considering their value in relation to the cost of the procedure - although I would note that you should also take into account the possible value of those BTC in the future.
OP has no other choice if he can not recover data by himself but using third party data recovery is risky. They can say we fail to recover your data but in fact they got it successfully and stole that wallet file and got access to bitcoin. We can not know what they do after we pass our devices and drives to them for data recovery.
Hopefully OP will recover his wallet successfully and bitcoin in that wallet will be intact. However, this accident reminds OP the importance of wallet backups. If you have a Bitcoin wallet, back it up before you use it for receiving, storing and sending bitcoin.
