I have an Acid problem...

So, as the bike was cartwheeling through the graveltrap, fuel tank torn loose and flapping around, the battery [prior to, and during, it's ultimate ejection from the bike] sprayed a fair bit of acid all over the harness, relays, ecu, etc.
Question: Is there an easy way to neutralize the acid, short of squirting a baking soda solution all over everything, and then hosing it all off? I'm not big on the idea of seriously soaking everything.
Will misting it all with WD-40, and wiping it down, neutralize acid? [it seems to have so many other uses]
Or is there something else out there that will accomplish this?

Thanks in advance for all your tips/advice

I would do the baking soda and rinse with a lot of destilled water. Do it as SOON as you can.

Will do. Thanks.
