Replacing Rusted anode rod?

Originally posted by lostagain Why don't you do your own experiment with various penetrating oils and tell us which is best.  Maybe you could make a video and post it to YouTube.

Unless someone happened to have a bunch of equally exposed heavily corroded bolts laying around it would take too long to replicate a real world test. The Navy has probably done it, they do lots of long term corrosion testing in various climates.

So I understand why he did it the way he did, he's trying to do an accelerated test. The problem is unless there is actual long term data to support the accelerated testing protocol it's just guesswork.

In this case if we were trying to remove slightly corroded bolts with slightly more torque than was used to install them this would probably be a good test. But we're not, if we were doing that we would just take em off right off and not need penetrants, or heat, or impact drivers.


I'll keep using my PB Blaster, it smells worse than the other ones so it has to be better, right?

No matter what penetrating oil one uses, keep in mind that if you drink or wash dishes useing "tank water" you need to be careful not to get oil inside the tank and into the water.  It's not likely that any of it is very good for you to ingest and it probably doesn't taste very good either.  As for the brand, obviously, use what works for you or makes you happy.
