Is there any issue with using a drop or two of PB-Blaster on your spoke nipples?

I just did the wheels on my winter bike, because although I have all SS spokes, a few were sticking and wouldn't let me do a minor adjustment after riding it all winter in snow and deep, salty slush.

It seemed to work well...
-But would the rubber be adversely affected perhaps?

Are you talking about the tires? Just wash the wheel and forget about it.

+1 a drop or two to do the job, then washed off the rubber makes perfect sense and sure beats twisting off spokes because of seized nipples.

Aren`t you sortof asking the question after the fact? I oil my own spokes every year because I drive in the winter too - but have never felt any need to use anything except a light oil. A few people on here apparently use antiseize on their spoke threads which can`t be a bad idea.

But to answer your question - there apparently have been several reports of PB-Blaster eating engine seals in both marine and automotive installations. Don`t know hor similar the chemistry is between engine seals and the butyl rubber in your tubes and tires - but sounds like you may be about to find out.

Miracle products are funny - the promoters never tell the whole truth about what they`re selling. STP Oil Treatments is one of the most infamous for misleading advertising. The most recent seems to be those tire sealants that void your warranty and cause tires to delaminate.

Yes - I was a little concerned about the butyl rubber tubes, and I am asking after the fact, because I hadn't really considered it beforehand. I've used PB-Blaster on other components even adjacent to plastic (freeing sticky calipers and the like) with no ill effects, but thinking about trapped alongside my inner tubes prompted me to ask if anyone had any such experience.
- It sounds like no one is aware of a specific taboo, so I feel a bit more confident about it.

Thank you all, for your replies!

A drop or 2? No, no issues.
