I have a old trusty pump that over the years has the presta head filled with tubeles goo. Noways it pumps the tires very slow. Is there any chemical way to remove it without melting the plastic?

    What kind of pump? If its a floor pump with a hose, you can often replace the whole head and hose as an upgrade.

  • @Criggie yes, floor pump with a hose. I'll consider replacing the head too, thanks.

You should be able to disassemble the pump head and clean out the blockage manually.

I’d try 70% isopropyl alcohol as a solvent to help remove sealant.

  • Thank you, some medical spirits + smal hex key did the job. Hopefully it's work better now, otherwise I'll change whole head/hose as @Criggie adviced
