Thanks Frank, I used that mixture once before on something simple and it worked really well.

Yesterday however............ severely rusted uni joints in an old pto shaft and yokes for an old post hole digger.

Circlips mostly gone, couple of the ends of the caps had gone with the needles. Soaked the whole lot in phosphoric for a couple of days so all the surface rust was gone and I could see what I was dealing with. Got one yoke off one end, but nothing else was going to budge with a socket and BFH.

Got out the little bottle of above mixture and gave the problem areas a couple of good squirts and a rest for an hour.

All the cups came out relatively easily after that and I could see that the mix had penetrated around the cups through the film of rust between them and the yokes. Saved major grief!

cheers, DL
