So, I have a variety of games bought in the 80's and 90's, not to mention systems and controllers that need to be cleaned up. None of them have ever actually been cleaned. On the contrary, the usual "maintenance" method has been blowing into the cartridges and slots. Needless to say, all this retro stuff needs some loving. The systems, games and controllers are (for): Sega Megadrive, NES, SNES and N64.
What do you recommend? I have been browsing eBay for a kit that includes the keys needed to open the systems and games, swabs, cleaning fluids etc. Is the NES Cleaning Cartridge actually woth something or just another fancy trinket / collector oddity? I don't expect to get the systems clean from dust and oxidation with a simple cleaning cassette, but if it's actually useful in keeping the cassette slot clean to a degree, it might be nice.
But in short: I need a cleaning set for mah retro stuff. Most of my systems and games are PAL. But the keys open any systems and cassette regardless of the region, right?
