How to unclog a grease ZERK that isn't flowing Kubota or Land Pride - zerk fittings are similar

I went to grease the grapple and one of the grease fittings a "ZERK" was leaking grease all over and not going into the place it was needed. Here's what I encountered.

I really like my Lock-N-Lube grease gun fitting and goes well with my DeWalt Grease Gun. I recommend you get the extended Lock-N-Lube, I have both short and long versions.
