Mr Sheen and Nifti were the two products used by operators as far back as I can remember. Mr Sheen for playfields. Not only did it clean, but it polished. I'm not surprised that people still use it - but make sure you spray onto a cloth, not directly on the playfield.

I reckon I’ll give it a go then, good advice spraying onto a cloth first. I can imagine lots of overspray in hard to reach places.
