Goo in the core

Tubeless valve cores are clogging up with goo makin it hard to inflate the tire.

Anyone know of a good solvent or some simple way to clear it? preferably without removing the tire, valve blah blah blah........

unscrew the valve core and take it out
when you have it out - take out the little rod that goes thru the core (unscrew the little barrell at the top first) give it a good clean and oil it all up before reassembling to prevent the core getting clogged-up again

Looks like il have to dismanlte the whole lot so.....

Any of the following. May dissolve tyres and/or bicycle and/or your floor and shoes as well.

Toluene
Xylene
Dichloromethane
1,2-dichloroethane
N-methylpyrrolidone

Where's Heald when you want him?

I have xylene, cool....

Is it ortho, meta or para?

Meta. I think!

Why?

Curiosity really. I always think meta-substituted aryl rings are the prettiest - would you not agree?

holy s**t
