What's the best way to clean this up?

I'm curious, if this was on an old shed, why have a pristine version?

What use is this? I'm just being nosy!

It's from an 8 year old shed that we just spend $1,500 restoring to like new condition. This is a label that is bolted on the inside of the shed and it just looks bad with the water stains and crap on it. Could be my OCD kicking in.

OK, thanks!

I guess if I'd spent that money, I might feel the same.
