A good rinse or wet towel wipe down should do the trick.

+1. Also, if there is coraline left on the glass, then either going at it with a razor will get rid of it quick, or you can spray a vinegar/water solution on it and rub with a paper towel (works well in the corners where the silicone is as well as the overflow box).

Dump some fresh water down the gap in the overflow. I can't remember how wide those gaps are, but maybe a chopstick or a wooden skewer will fit and you can flush fresh water downs and use the chopstock to knock out any calcerous worms and algae.


If it seems really dirty, running the tank for a while with water should flush anything stuck in the overflow gap out.

You can use full strength vinegar or bleach for the really difficult or hard to reach bits.

It's not complicated.
Salt dissolves in freshwater. Lot's of freshwater that's all you'll need. Adding warm freshwater will dissolve the salt faster than cold water.

I don't know the salinity levels of marine tanks available off hand, but the tank itself offers such a small amount of surface area, I'd be willing to bet that just merely filling it with freshwater would effectively dilute any remaining salt to the point where it was unnoticeable.

Anyways, to be safe, a damp cloth wipe-down, or a hose-down and rinse outside.

I wouldn't worry too much about overflows and such, unless they are literally blocked by salt build-up, it likely won't matter when you fill the tank with freshwater.

Odds are, the previous owner of the tank drained it, and then put it into storage/up for sale (and even if they didn't, 98+% of the salt would be on the bottom of the tank).

If you see a whitish residue that you are concerned about, it's most likely carbonate buildup- also referred to as lime, scale, hardwater stains, etc. It may be unpleasant, but it's minor enough to not be concerned with at all. otherwise, the vinegar or razor techniques should work pretty well.
