Its the greatest!

I just got my stem unstuck and removed, and popped a stuck cotter out too

Sure its just another penetrating oil, but I'm a new devotee

Try PBlaster. I think it works even better.

The way some of u advertise your miracle oil/tools/lastest discovery, u'd think it will cure cancer.

Sheldon says ammonia works wonders on stuck aluminum seat posts.

It's still in early trials, but we've got high hopes. If all goes well we could bring a product to market in a decade.


..you don't have to give a sh1t its ok.

I was swapping out some pedals that had never been removed. Apparently the shop that assembled the bike didn't bother to grease the threads. One side was seized. I put a wrench on it, then beat the wrench with a hammer. Tried a long wrench and beat that too. Then I sprayed on a bit of PB blaster, then tapped it lightly and the pedal came right off.

I don't usually need it for a bike components, but I routinely use PB blaster on the nuts or bolts on cars where they might be rusted on.

I discovered it a few years ago doing vintage European off road motorcycle restorations.

Ok, who has the Kool-Aide?

This stuff is suppose to be better than the PB blaster :

From my days of industrial machinery maintenance Kroil (kanolaobs) is the best stuff - really amazing. I don't have a local source for Kroil, so I've found PB Blaster works great too.

PS- ive heard WD-40 cures arthritis








thats a joke, btw. itll only make your elbow smell macho

I'll have to find some of this PBlaster next time i've got stuck parts

I got back from work after letting the liquid wrench work on the left side cotter all last night and today and 2 good shots with the hammer and it fell right out.

I'm psyched, the only things left to remove from the frame are the BB and the Forks and those parts are all loose and ready to come off. I anticipate having the frame at the auto body shop by tomorrow or monday at the latest.

That's what I've read. PB Blaster is readily available, but I think you'd have to order the Kroil stuff.

If you click on the link in my earlier past link, it goes to the maker of Kroil. You can get a free sample of any product they sell and, I believe, order on-line. I've requested a free sample, hope it works on my bike's stem. Got a stuck seat post too, but Sheldon Brown says penetrating lubricants don't work well on aluminum and suggests ammonia. If it words, sure is a cheap solution. Stems, on the other hand, are usually a steel on steel problem so penetrating stuff probably works better.

I'm pretty sure my stem is aluminum for what thats worth.

The stem, most probably, not the wedge. Its the wedge that gets stuck in the head tube, not the stem itself. Penetrating lubricants work on the tube and the wedge.

Another vote for Kroil (Kano Labs).

A co-worker of mine had some and he let me use it for some ultra-stuck bolts. I couldn't find it locally either Tom but had to get some, so I ordered it from Kano.

Yep, PB Blaster is good, but Kroil is superior.

I used some PB Blaster tonight to remove a windshield wiper arm. Worked great.

Ive got a kink in my chain and I've tried wd-40 and white grease but its still stiff at one link. Would it be worth trying liquid wrench or pb blaster?

Have you removed the chain recently with a chain tool. Sometimes the link that you removed and then "put back on" remains a bit stiff. Try bending it side to side to "free" it up. If that doesn't work, try using a small screw driver to pry (very carefully and gingerly" the link a bit free so it can bend smoothly.

kroil > all.


seriously - my coworker works on antique hit and miss engines and tractors and has un-stuck engines that have been sitting outside w/ the head off for years. We also use it at work on rusty exhaust nuts.

The chain has never been off but the bike sat up for several years and one section felt like the original grease had dried up so much that it was hard. I'll try the bending and prying techniques. Thanks

Thanks gr23932.... I bent the chain from side to side and it freed up the trouble spot!

Kroil and PB Blaster user here Haven't had any ugly enough to try the ammonia trick on...yet

Just a word of caution, every time I've used ammonia to try to free up a seized aluminum part it has completely destroyed the finish to a most likely unrepairable state (I haven't tried polishing it out though). So, I wouldn't risk it on parts you plan on reusing.
