Liquid Wrench

02-23-2005, 06:51 PM

Hello,

I got a stuck seat post in a seat tube. Someone suggested
Liquid Wrench. I found it was just some lubricant. Will
the more readily available WD-40 do the job?

In my experience, not nearly as well.

That probably won't help either because, although you didn't say so, I
suspect you have a steel frame and an aluminum seat post. When these
two corrode together aluminum expands enough to stretch the seat post.
Yours may not yet be at that point but it probably cannot be removed
non-destructively.

The way frame builders remove these is to saw them off, bore them out
to a thin shell and grind away a slot in one side to collapse the
aluminum remains to remove them. Oil bases lubricants will not help.
An acid solvent might work its way in there but I doubt it.

There's Liquid Wrench penetrating oil, and there's
Liquid Wrench lubricant.

Maybe so, maybe no. See: [Only registered and activated users can see links. ]

Ammonia is good for this...I believe it's a base, not an acid.
