I was given several items by a coworker, one of which was a 10g tank that I want to turn into a divided NPT tank for my boy and a new friend. Only issue is that it has definitely not been used in a long time, and there are stickers all over the tank. It looks like someone tried to remove the stickers, but was unsuccessful. Is it safe to use something like goof off if I wash it REALLY well afterwards?
Here are a few pics of the items so you can see what I'm working with.
