Bud, I know that it's hard to believe right now but you are one of the lucky ones.
Although the damage is bad , it's not a total loss.
I'm sorry that this has happened to you.
The water is acidic , you will need to wash and rinse the bikes and any other metals that you want to save. along with everything else
As an added threat that we didn't have up north, you have misquitos and Zeka virus to contend with , get plenty of Off , foggers, and torches.
So sorry.
