A recent post recommended applying Kroil daily for a week to loosen up
a stuck anode rod in a water heater.

- Is Kroil significantly better than more commonly available brands
such as Liquid wrench?

applications?

After application of the penetrating oil give it a couple of taps with
a hammer. This used to be part of the directions on Liquid Wrench
label. Apparently the vibration helps it to penetrated.Also trying to
tighten it a little more will often help break it free better than
trying to loosen it. If it gives a little on tightening then
alternately loosen and tighten while adding more oil until it frees up

And it helps to use a back up wrench wherever possible so you don't twist
the whole thing off.
