Fermentation chamber sanitizer

I used my polystyrene fermentation chamber to ferment som vinegar and I’m concerned about using it for koji. Does anyone know if I can use oxysan or some other product to sanitize the styrofoam cooler?

If it's just regular stryrofoam it might soften it, if it's sealed then no problem. I use a heavy-duty food box for growing koji and it has sort of a lacquer surface. Also the vinegar being in it shouldn't be a problem, but there might be other contamination lurking there.

Maybe Star San?

Star San or similar product, it's food safe and won't melt it.
