The old controllers should be easy to take apart. Clean the plastic with Dawn and warm water, and use some DeOxit for the switch contacts (with Radio Shack basically dead, I have no idea where you'd buy it retail, now). Then, on the PCB part of the switches, some thin dielectric grease should make it feel nice and improve its longevity. If you have none, Super Lube synthetic PTFE (the mineral oil type, not the silicone type), from Harbor Freight, Walmart, or Ace, should do the trick (just a small very thin coating should do, and that tube will likely be a lifetime supply).
That's fine for the few that just need to be cleaned, but many (probably more) need replacement rubber parts too, unfortunately. The carbon deteriorates under the rubber domes and the domes themselves tear with repeated use.
My Super Famicom has two controllers but I don't want to use the brand new one (keep it new). The directional pad on the used/worn SFC controller feels loose and frequently detects down when you press right. The directional pad on an NES I got at the flea market last week is insensitive on the left side. Even decades ago this was so common that they sold controller repair kits with replacement buttons and rubber at major department stores (I got my "Doc's Nintendo Controller Repair Kit" from K-Mart).
