All you need to do, is get a bike innertube (can be found, or bought new for about $5), and cut about 12" off of it.
To use it, just wrap the innertube around the 4 edges of the square handle on the backside of the cap, then twist it off as you normally would, and voila! Works every time, and is much cheaper and easier than using a rubber strap wrench.
Is it groundbreaking? No, not really. Could somebody find it useful? Yeah, I think so, which is why I figured I'd post it.
Thanks, and happy spudding!
