Ironically, I have a tank that I just vis'd which has some minor rust spots growing at the bottom... the sort of raised, fluffy rust that comes from some water spray, doubtless from crews hooking up for a fill on a boat at some point.
Scratching them clean with my long coat hanger tool thingie would take WAY longer than I'd want to invest, so perhaps it's time for me to look into one of these tank whip tools to clean out the inside, rather than paying for a tumble which may do as much harm as good (per Joel's post).
The DecoStop thread(s) detail how to make the tool, and I'll probably go that route, but I still wouldn't mind seeing some photos of someone else's tank tool, just to make sure I do it correctly. As a band-aid, if anyone local has one I could see in person, that would be helpful as well.
It would be easier for me to just pay for a tumble, but I'd like my tanks to last, so it seems likely this is the more prudent approach, even moreso than trying to set up a way to tumble them myself. (Especially considering my condo leaves me next to nowhere I can really do messy work, and the wife is very intolerant of things that take up more space at home!)
I've seen this sort of thing before, on other tanks, and had it tumbled out quite easily, but since it seems inevitable that this will happen again in the future, having the right tool on hand seems like a great way to go.
One question for those who are well familiar with these tools, too: Does it make more sense to get the stainless wire for a DIY whip, or is the plastic weed-wacker material a safer choice for the inside of the tanks? I know the plastic wears out/down faster and needs replacing, but it just seems safer than metal on metal, at least in my mind.
