I am currently working through a Doctor Who pinball I recently purchased. I have now got to the mini playfield and I have noticed that someone previously has used grease on the main bracket instead of silicone grease.
Has anyone else had the same issue and if so what was the technique used to clean the grease off. I was going to use some degreaser and wash it off with water or a damp rag but I did not want to get to a stage where it starts to rust out either.
