I recently bought the NuBall Ball Rejuvinator from Salmon Creek off of Amazon.
I put almost all my stuff in it. New and old. Some with at least 100 games on it. Some I wouldn't be surprised if they had 500+ games on it. If even sanded them down to 500 with my ball spinner first before putting it in.
Bottom line, if it was a solid a ton of oil came out. Hybrid got some oil out of it. If it was a pearl very little oil came out of it.
