    Presta Plugged with Stan's

    I've been tubeless for a year and I just plugged one of my presta valves. Any pro tips on how to clean it out?

    And, I'm aware replacing it for $.65 is the best route but I need a fix to hold me over until I can get one.

    Thanks.

    Reverse air pressure. If you have a compressor and schrader adapter or presta chuck just dial up the pressure and blow the chunk in. If you have a small hobby torch you could try heating the valve stem too. The metal will expand a bit and it'll blow right in.

    Have you tried removing the core and reaming it?

    Poke it with a stick. It's really that simple.

    It's a plastic body so torch would be bad. I do have a compressor and an adaptor so I can try that.

    I don't think there is a chunk in the body, the valve itself sticks when unscrewed and pushed in and out. And it's almost impossible to pump with a hand pump it's so restricted. So I guess I was more curious about soaking the core in something to remove the latex.

    I'll go give it a shot. Thanks.

    Remove the valve and clean with alcohol. Then take a thin q-tip and clean out the stem.

    I got mine plugged recently so I removed the valve core then reamed it out with the right sized Allen wrench...... BINGO 👌👌👌

    Soaked the core in alcohol for about 30 minutes. Fixed.

    Thanks
