Salt creep prevention

[ademster]

On my 375 Gal DT it is Euro braced along with a big center brace
tank is acrylic and I have a lot of salt creep build up on the underside of the braces limiting the amount of light going through.

What are methods used to prevent it from forming there?

I'm going to tag along, but the only thing I know of is to wipe it down on a regular basis to prevent it from getting to bad.
I know that's probably not the answer you're looking for, but it's the only one I know.
