I'm having the same issue. I searched the net and found a trade show video on this https://locknlube.com/collections/g...ts/grease-buster?variant=32921003327572. It seemed to work well during their demonstration, so I pulled the trigger and ordered one. Received it last week. Haven't had a chance to use it yet. Will let y'all know when I do and how it works.
