Penetrating oils tested.

Came across this, and even tho my 2 favorites weren't tested, interesting…. (My Favorites are CRC Freeze-off, and PB-Blaster.)

Interesting on how well old brake fluid worked….

 

I use PBBlaster although its very hard to get hold of in the UK.
Works very well and smells oddly nice, far better than plus gas

Where can you get seafoam in the UK?

Not seen the others for sale but not really looked, used WD40 but now changed to Plusgas.

There is good things to be said about ATF Fluid and Acetone mix.  Google it, you will see.
 

I've had good results using PlusGas, but i do like to apply it repeatedly to the offending fastener over a couple of days if I've got the time.

His voice!!

Waka waka! 

I've had good results with Loctite Freeze and Release.
