Grey Tank Overflow

[boylanag]

Oops!! I usually leave the grey tank valve opened so that we can use our washer/dryer. It drains into our grey tank. The other day, I closed it to collect some water to flush the sewer hose after a black water tank emptying. Well, I forgot to open it again and yesterday we were leaving to go out and Carol was doing wash. We saw water dripping from the hitch pin box, ran back inside and saw that the floor around the washer was soaked. We found water in the basement and it wasn't until finding water in the shower floor that we learned that the grey tank valve was closed. Now that the tank has been drained and apparently no damage to the tank, my question is - how can we make sure that it dries inside the nose and other hidden areas? Should it be OK to just leave it to air-dry by itself? We are in Central Florida where the weather is going back and forth from rainy to super low humidity days and then back again.
