Tufo tubs blocked with sealant

dont know if anyone can offer advice. Had some tufo tubs fitted to my Zipp rims, and the guy suggested adding sealant. This was months ago, and worked well. However, it is now nearly impossible to get air into it. I assume that sealant has got into the valve. Really hope I don't need to replace the tub. Does anyone have any advice, tips? Hope so. Thanks. Graham

    Ive had this before when people have those self sealing innertubes, a big blast from a track pump cleared it each time

    remove the valve core - clean - replace.

    You can get a maggot of sealant build up behind the valve core.
