Love this stuff, I use it on my motorbike, pinball playfields for a general clean after a good wax has been layed down. It even works great on LCD screens and Laptops, makes a laptop look like new. Seems to last for ages too. A friend gave it to me a few years ago and was reluctant at first but now I swear by it. :)

Spray onto a cloth and not onto the playfield as is froths up and shoots out at a rate of knots and will splatter where you don't want it to go.
