Started my clean. Changed playfield lights to #47s as I want to minimise future yellowing due to the heat emitted by the #44s. All the rubbers are changed and the playfield was cleaned with Magic Eraser/Isocol and polished with Mill Wax. All chrome and metal was polised with Nu-Clean.
Fortunately there is minimal wear on this original playfield and all the plastics and gates are in good nick.
