I remember when I was a child - School holidays were spent cleaning pinball machines as they were brought in and reconditioned for their next route. This was around 1975-76. NIFTI was sprayed liberally on the cabinet and an old paint brush was used to scrub the dirt and grime. Every time I see NIFTI at Coles, I buy the entire shelf - sometimes 20 bottles. It is the best pinball cleaner out there !
