Mildew on Wood Veneer Floor

[Tori]

We live aboard and were gone for five days upon returning home I smelled something odd...all of the clothes stored in the lockers on the port side were damp and mildewed...more searching under the rug on the wood veneer cabin floor wet and mildew.
Apparently the rigid plastic water tank leaked alot while were gone...clothes, lockers,rug easy fix. What to do with the floor it is discolored,kinda squishy in two spots and the laquer is peeling off.
I scrubbed it and dried it and put a fan on it...what else?
